Description

モータ駆動装置の取付板材及び取付構造Mounting plate material and mounting structure for motor drive device
　本開示は、モータ駆動装置の取付板材及び取付構造に関する。 This disclosure relates to a mounting plate material and mounting structure for a motor drive device.
　一般的に、制御盤の内部には、モータ駆動装置が実装されている。モータ駆動装置は、制御盤の支持部に着脱可能に固定されている。モータ駆動装置が支持部に固定された状態において、モータ駆動装置の放熱部分は、支持部に形成された開口部に通されている。 Typically, a motor drive unit is mounted inside the control panel. The motor drive unit is removably fixed to the support part of the control panel. When the motor drive unit is fixed to the support part, the heat dissipation part of the motor drive unit passes through an opening formed in the support part.
　従来、制御盤の支持部は、制御盤の内部を２つの空間に区画している。モータ駆動装置の放熱部分は、支持部の開口部に通されているので、２つの空間のうちの一方の空間に配置されている。モータ駆動装置が支持部に固定された状態において、支持部の開口部は、モータ駆動装置によって閉じられている。このような構成であるので、２つの空間のうちの他方の空間は、一方の空間と連通されていない。一方の空間は、外気と連通可能とされている。 Conventionally, the support part of the control panel divides the inside of the control panel into two spaces. The heat dissipation part of the motor drive unit is passed through an opening in the support part and is therefore located in one of the two spaces. When the motor drive unit is fixed to the support part, the opening in the support part is closed by the motor drive unit. With this configuration, the other of the two spaces is not connected to one of the spaces. One of the spaces can be connected to the outside air.

　モータ駆動装置を小型化した場合、モータ駆動装置を制御盤の支持部に取り付けると、支持部の開口部がモータ駆動装置によって閉じられない。すなわち、一方の空間と他方の空間とは、互いに連通可能とされている。一方の空間と他方の空間とが連通可能とされている場合、外気と連通可能とされている一方の空間内の汚れた空気が他方の空間内に流れ込んでしまう。他方の空間内に汚れた空気が流れ込むと、制御盤が故障するおそれがある。そのため、モータ駆動装置は、安易に小型化することができない。 If the motor drive device is made smaller, when the motor drive device is attached to the support part of the control panel, the opening of the support part is not closed by the motor drive device. In other words, one space and the other space are capable of communicating with each other. When one space and the other space are capable of communicating with each other, dirty air in one space that is capable of communicating with the outside air will flow into the other space. If dirty air flows into the other space, there is a risk of the control panel breaking down. For this reason, the motor drive device cannot be made smaller easily.
　モータ駆動装置を交換する際、モータ駆動装置は、旧機種から新機種に置き換えられることがある。新機種のモータ駆動装置は、旧機種のモータ駆動装置と比較して、小型化されている場合がある。小型化された新機種のモータ駆動装置を制御盤の支持部に取り付けようとすると、上述したように、制御盤の故障という問題が生じる。そのため、旧機種のモータ駆動装置から小型化された新機種のモータ駆動装置に交換する際には、元の制御盤を装置から取り外した後、新機種が適用可能な支持部を有する制御盤を装置に取り付ける必要がある。 When replacing a motor drive device, the motor drive device may be replaced with a new model from an old model. The new model of motor drive device may be smaller than the old model of motor drive device. When attempting to attach the new model of smaller motor drive device to the support part of the control panel, as mentioned above, the problem of control panel failure occurs. Therefore, when replacing an old model of motor drive device with a new model of smaller motor drive device, it is necessary to remove the original control panel from the device and then attach a control panel having a support part to which the new model can be applied to the device.
　そこで、上述した問題を解消するために、制御盤の支持部の構成はそのままで、制御盤の支持部に小型化されたモータ駆動装置を容易に取り付けることができる取付板材、及びその取付板材を備える取付構造が望まれている。 In order to solve the above problems, there is a need for a mounting plate that allows a miniaturized motor drive unit to be easily attached to the support part of the control panel while keeping the configuration of the support part of the control panel unchanged, and a mounting structure that includes this mounting plate.
　本開示の取付板材は、制御盤の支持部にモータ駆動装置を取り付ける取付板材であって、前記支持部に前記取付板材を固定する板固定部が配置される配置部と、前記取付板材に前記モータ駆動装置を固定する装置固定部が固定される被固定部と、を備え、前記支持部の開口部の少なくとも一部を塞ぐように設けられる。 The mounting plate of the present disclosure is a mounting plate for mounting a motor drive unit to a support part of a control panel, and includes a placement section in which a plate fixing section for fixing the mounting plate to the support part is disposed, and a fixed section in which a device fixing section for fixing the motor drive unit to the mounting plate is fixed, and is arranged to cover at least a portion of the opening of the support part.

　以下、本開示の一態様に係るモータ駆動装置の取付板材について、図面を参照して説明する。図１から図４を参照して、第１実施形態に係るモータ駆動装置の取付板材１について説明する。取付板材１は、制御盤２の支持部３にモータ駆動装置４を取り付ける。制御盤２は、中空状の筐体５を有している。筐体５は、モータ駆動装置４が収容される本体６と、本体６の開口部を開閉する扉７とを有している。本体６は、略矩形の箱状で、中空部を有している。本体６は、前方（図１における左方向）に開口した開口部を有している。本体６の開口部は、扉７によって開閉可能とされる。扉７は、図示しないヒンジによって、本体６の前部に設けられる。 Below, a mounting plate for a motor drive device according to one embodiment of the present disclosure will be described with reference to the drawings. A mounting plate 1 for a motor drive device according to a first embodiment will be described with reference to Figs. 1 to 4. The mounting plate 1 mounts a motor drive device 4 to a support portion 3 of a control panel 2. The control panel 2 has a hollow housing 5. The housing 5 has a main body 6 in which the motor drive device 4 is housed, and a door 7 for opening and closing an opening of the main body 6. The main body 6 is substantially rectangular box-shaped and has a hollow portion. The main body 6 has an opening that opens to the front (left direction in Fig. 1). The opening of the main body 6 can be opened and closed by the door 7. The door 7 is attached to the front of the main body 6 by a hinge (not shown).
　本体６の内部には、モータ駆動装置４を支持する支持部３が設けられる。支持部３は、正面視において略矩形の板状である。支持部３は、板面を前後方向（図１における左右方向）に向けた状態で、本体６の内部に設けられる。図３に示すように、支持部３は、支持部３の厚さ方向（図１における左右方向）に貫通する開口部８を複数有している。複数の開口部８は、左右方向（図３における左上と右下とを結ぶ方向）に並んで配置されている。支持部３の開口部８は、正面視において略四角形状である。図示例では、支持部３の開口部８の数は、３つであるが、これに限定されるものではなく、２つであってもよいし、４つ以上であってもよい。支持部３の開口部８の数は、複数に限定されるものではなく、１つであってもよい。 A support section 3 that supports the motor drive device 4 is provided inside the main body 6. The support section 3 is a plate-like shape that is approximately rectangular when viewed from the front. The support section 3 is provided inside the main body 6 with the plate surface facing the front-rear direction (left-right direction in FIG. 1). As shown in FIG. 3, the support section 3 has a plurality of openings 8 that penetrate in the thickness direction of the support section 3 (left-right direction in FIG. 1). The plurality of openings 8 are arranged side by side in the left-right direction (direction connecting the upper left and lower right in FIG. 3). The openings 8 of the support section 3 are approximately rectangular when viewed from the front. In the illustrated example, the number of openings 8 of the support section 3 is three, but this is not limited to this and may be two, or may be four or more. The number of openings 8 of the support section 3 is not limited to multiple, and may be one.
　支持部３は、筐体５の内部を前後方向に区画する。具体的には、筐体５の内部は、支持部３によって、前側に位置する第１空間９と、後側に位置する第２空間１０とに区画される。第１空間９は、本体６の開口部を扉７で閉じることで形成される。第２空間１０は、外気と連通可能とされる。図示例では、筐体５は、後壁１１の上部に位置する複数の上側貫通孔１２と、後壁１１の下部に位置する複数の下側貫通孔１３を有している。複数の上側貫通孔１２は、後壁１１の上部において、左右方向に並んで配置される。複数の下側貫通孔１３は、後壁１１の下部において、左右方向に並んで配置される。これにより、第２空間１０は、複数の上側貫通孔１２及び複数の下側貫通孔１３を介して、外部と連通される。 The support 3 divides the interior of the housing 5 in the front-rear direction. Specifically, the interior of the housing 5 is divided by the support 3 into a first space 9 located on the front side and a second space 10 located on the rear side. The first space 9 is formed by closing the opening of the main body 6 with the door 7. The second space 10 is capable of communicating with the outside air. In the illustrated example, the housing 5 has a plurality of upper through holes 12 located on the upper part of the rear wall 11 and a plurality of lower through holes 13 located on the lower part of the rear wall 11. The plurality of upper through holes 12 are arranged side by side in the left-right direction on the upper part of the rear wall 11. The plurality of lower through holes 13 are arranged side by side in the left-right direction on the lower part of the rear wall 11. As a result, the second space 10 is connected to the outside via the plurality of upper through holes 12 and the plurality of lower through holes 13.
　図１に示すように、制御盤２の内部には、複数のモータ駆動装置４が実装される。各モータ駆動装置４は、制御部１４、フランジ１５及び放熱部１６を有している。 As shown in FIG. 1, multiple motor drive units 4 are mounted inside the control panel 2. Each motor drive unit 4 has a control unit 14, a flange 15, and a heat dissipation unit 16.
　制御部１４は、前側に位置している。フランジ１５は、略四角形の外形を有する板状である。フランジ１５の上下長さは、制御部１４の上下長さよりも長い。フランジ１５は、板面を前後方向に向けた状態で、制御部１４の後面に設けられる。フランジ１５が制御部１４に設けられた状態において、フランジ１５の上端部１７は、制御部１４よりも上方に延出しており、フランジ１５の下端部１８は、制御部１４よりも下方に延出している。フランジ１５は、フランジ１５の厚さ方向に貫通する貫通孔１９を複数有している。具体的には、フランジ１５の上端部１７及びフランジ１５の下端部１８は、フランジ１５の厚さ方向に貫通する貫通孔１９を複数有している。図示例では、フランジ１５の上端部１７に２つの貫通孔１９，１９が配置されているとともに、フランジ１５の下端部１８に２つの貫通孔１９，１９が配置されている。フランジ１５の上端部１７に配置される２つの貫通孔１９，１９は、左右方向に離隔しており、フランジ１５の下端部１８に配置される２つの貫通孔１９，１９は、左右方向に離隔している。放熱部１６は、後側に位置している。放熱部１６は、制御部１４の後面に設けられる。放熱部１６は、制御部１４で発生した熱を放熱する機能を有している。典型的には、放熱部１６は、ファン及びヒートシンクを有している。なお、制御盤２の内部に実装されるモータ駆動装置４は、１つであってもよい。 The control unit 14 is located at the front side. The flange 15 is plate-shaped with an approximately rectangular outer shape. The vertical length of the flange 15 is longer than the vertical length of the control unit 14. The flange 15 is provided on the rear surface of the control unit 14 with the plate surface facing the front-rear direction. When the flange 15 is provided on the control unit 14, the upper end 17 of the flange 15 extends upward beyond the control unit 14, and the lower end 18 of the flange 15 extends downward beyond the control unit 14. The flange 15 has a plurality of through holes 19 penetrating in the thickness direction of the flange 15. Specifically, the upper end 17 of the flange 15 and the lower end 18 of the flange 15 have a plurality of through holes 19 penetrating in the thickness direction of the flange 15. In the illustrated example, two through holes 19, 19 are arranged at the upper end 17 of the flange 15, and two through holes 19, 19 are arranged at the lower end 18 of the flange 15. The two through holes 19, 19 arranged at the upper end 17 of the flange 15 are spaced apart in the left-right direction, and the two through holes 19, 19 arranged at the lower end 18 of the flange 15 are spaced apart in the left-right direction. The heat dissipation section 16 is located on the rear side. The heat dissipation section 16 is provided on the rear surface of the control section 14. The heat dissipation section 16 has a function of dissipating heat generated by the control section 14. Typically, the heat dissipation section 16 has a fan and a heat sink. Note that the number of motor drive units 4 mounted inside the control panel 2 may be one.
　複数のモータ駆動装置４はそれぞれ、１枚の取付板材１を介して、制御盤２の支持部３に取り付けられる。すなわち、第１実施形態では、複数の取付板材１が用いられている。制御盤２の内部に実装されるモータ駆動装置４が１つの場合には、使用される取付板材１は、１枚である。なお、図示例では、用いられるモータ駆動装置４の数は、３つであるが、２つであってもよいし、４つ以上であってもよい。 Each of the multiple motor drive units 4 is attached to the support portion 3 of the control panel 2 via one mounting plate 1. That is, in the first embodiment, multiple mounting plates 1 are used. When one motor drive unit 4 is mounted inside the control panel 2, one mounting plate 1 is used. In the illustrated example, three motor drive units 4 are used, but the number may be two or four or more.
　第１実施形態の取付板材１は、鉄などの金属製で、正面視において略四角形の外形を有する板状である。取付板材１の大きさは、支持部３の開口部８の大きさよりも大きい。具体的には、取付板材１の上下長さは、支持部３の開口部８の上下長さよりも大きく、取付板材１の左右長さは、支持部３の開口部８の左右長さよりも大きい。取付板材１は、支持部３に取付板材１を固定する板固定部２０が配置される配置部２１と、取付板材１にモータ駆動装置４を固定する装置固定部２２が固定される被固定部２３と、モータ駆動装置４の一部が通される装置開口部２４とを備える。 The mounting plate 1 of the first embodiment is made of a metal such as iron, and is plate-shaped with a generally rectangular outer shape when viewed from the front. The size of the mounting plate 1 is larger than the size of the opening 8 of the support portion 3. Specifically, the vertical length of the mounting plate 1 is larger than the vertical length of the opening 8 of the support portion 3, and the left-right length of the mounting plate 1 is larger than the left-right length of the opening 8 of the support portion 3. The mounting plate 1 includes a placement portion 21 in which a plate fixing portion 20 that fixes the mounting plate 1 to the support portion 3 is placed, a fixed portion 23 to which a device fixing portion 22 that fixes the motor drive device 4 to the mounting plate 1 is fixed, and a device opening 24 through which a part of the motor drive device 4 passes.
　第１実施形態では、板固定部２０は、ねじ（雄ねじ）である。そのため、支持部３は、板固定部２０がねじ込まれるねじ孔２５を有している。板固定部２０がねじであるので、配置部２１は、板固定部２０が貫通する貫通孔である。このような構成であるので、取付板材１は、板固定部２０によって支持部３の前面に着脱可能に固定することができる。具体的には、板固定部２０が取付板材１の配置部２１を介してねじ孔２５にねじ込まれることで、支持部３に取付板材１が取り付けられる。 In the first embodiment, the plate fixing portion 20 is a screw (male screw). Therefore, the support portion 3 has a screw hole 25 into which the plate fixing portion 20 is screwed. Because the plate fixing portion 20 is a screw, the arrangement portion 21 is a through hole through which the plate fixing portion 20 passes. With this configuration, the mounting plate 1 can be detachably fixed to the front surface of the support portion 3 by the plate fixing portion 20. Specifically, the mounting plate 1 is attached to the support portion 3 by screwing the plate fixing portion 20 into the screw hole 25 via the arrangement portion 21 of the mounting plate 1.
　取付板材１を支持部３に固定する際、４つの板固定部２０が用いられる。そのため、配置部２１の数及びねじ孔２５の数は、４つである。４つの配置部２１は、取付板材１の四隅に位置している。４つのねじ孔２５のうち、２つのねじ孔２５，２５は、開口部８よりも上側に位置している。この２つのねじ孔２５，２５は、左右に離隔している。４つのねじ孔２５のうち、残りの２つのねじ孔２５，２５は、開口部８よりも下側に位置している。この２つのねじ孔２５，２５は、左右に離隔している。なお、板固定部２０の数、配置部２１の数及びねじ孔２５の数は、４つに限定されるものではなく、複数であればよい。 When fixing the mounting plate 1 to the support 3, four plate fixing parts 20 are used. Therefore, the number of arrangement parts 21 and the number of screw holes 25 are four. The four arrangement parts 21 are located at the four corners of the mounting plate 1. Of the four screw holes 25, two screw holes 25, 25 are located above the opening 8. These two screw holes 25, 25 are spaced apart to the left and right. Of the four screw holes 25, the remaining two screw holes 25, 25 are located below the opening 8. These two screw holes 25, 25 are spaced apart to the left and right. Note that the number of plate fixing parts 20, the number of arrangement parts 21 and the number of screw holes 25 are not limited to four, and may be any number as long as they are multiple.
　第１実施形態では、装置固定部２２は、ねじ（雄ねじ）である。そのため、被固定部２３は、装置固定部２２がねじ込まれるねじ孔である。被固定部２３は、取付板材１の厚さ方向に貫通している。装置固定部２２がねじであるので、モータ駆動装置４は、前述した貫通孔１９を有している。このような構成であるので、モータ駆動装置４は、装置固定部２２によって取付板材１の前面に着脱可能に固定することができる。具体的には、装置固定部２２がモータ駆動装置４の貫通孔１９を介して被固定部２３にねじ込まれることで、取付板材１にモータ駆動装置４が取り付けられる。取付板材１にモータ駆動装置４が取り付けられた状態において、モータ駆動装置４の放熱部１６は、取付板材１の装置開口部２４に通されている。 In the first embodiment, the device fixing portion 22 is a screw (male screw). Therefore, the fixed portion 23 is a screw hole into which the device fixing portion 22 is screwed. The fixed portion 23 penetrates the mounting plate 1 in the thickness direction. Since the device fixing portion 22 is a screw, the motor drive device 4 has the above-mentioned through hole 19. With this configuration, the motor drive device 4 can be detachably fixed to the front surface of the mounting plate 1 by the device fixing portion 22. Specifically, the device fixing portion 22 is screwed into the fixed portion 23 through the through hole 19 of the motor drive device 4, thereby attaching the motor drive device 4 to the mounting plate 1. With the motor drive device 4 attached to the mounting plate 1, the heat dissipation portion 16 of the motor drive device 4 passes through the device opening 24 of the mounting plate 1.
　装置開口部２４は、正面視において略四角形状である。装置開口部２４の大きさは、支持部３の開口部８の大きさよりも小さい。具体的には、装置開口部２４の上下長さは、支持部３の開口部８の上下長さよりも小さく、装置開口部２４の左右長さは、支持部３の開口部８の左右長さよりも小さい。装置開口部２４の大きさは、モータ駆動装置４のフランジ１５の大きさよりも小さい。具体的には、装置開口部２４の上下長さは、フランジ１５の上下長さよりも小さく、装置開口部２４の左右長さは、フランジ１５の左右長さよりも小さい。 The device opening 24 is substantially rectangular in front view. The size of the device opening 24 is smaller than the size of the opening 8 of the support part 3. Specifically, the vertical length of the device opening 24 is smaller than the vertical length of the opening 8 of the support part 3, and the left-right length of the device opening 24 is smaller than the left-right length of the opening 8 of the support part 3. The size of the device opening 24 is smaller than the size of the flange 15 of the motor drive unit 4. Specifically, the vertical length of the device opening 24 is smaller than the vertical length of the flange 15, and the left-right length of the device opening 24 is smaller than the left-right length of the flange 15.
　モータ駆動装置４を取付板材１に固定する際、４つの装置固定部２２が用いられる。そのため、被固定部２３の数及び貫通孔１９の数は、４つである。４つの被固定部２３のうち、２つの被固定部２３，２３は、装置開口部２４よりも上側に位置している。この２つの被固定部２３，２３は、左右に離隔している。４つの被固定部２３，２３のうち、残りの２つの被固定部２３，２３は、装置開口部２４よりも下側に位置している。この２つの被固定部２３，２３は、左右に離隔している。４つの貫通孔１９は、前述したようにフランジ１５に配置されている。なお、装置固定部２２の数、被固定部２３の数及び貫通孔１９の数は、４つに限定されるものではなく、複数であればよい。 When fixing the motor drive unit 4 to the mounting plate 1, four device fixing parts 22 are used. Therefore, the number of fixed parts 23 and the number of through holes 19 are four. Of the four fixed parts 23, two fixed parts 23, 23 are located above the device opening 24. These two fixed parts 23, 23 are spaced apart to the left and right. Of the four fixed parts 23, 23, the remaining two fixed parts 23, 23 are located below the device opening 24. These two fixed parts 23, 23 are spaced apart to the left and right. The four through holes 19 are arranged in the flange 15 as described above. Note that the number of device fixing parts 22, the number of fixed parts 23, and the number of through holes 19 are not limited to four, and may be any number as long as they are multiple.
　取付板材１が板固定部２０によって支持部３に固定されるとともに、モータ駆動装置４が装置固定部２２によって取付板材１に固定されることで、モータ駆動装置４は、支持部３に着脱可能に取り付けられる。取付板材１が支持部３に固定された状態において、取付板材１の装置開口部２４と支持部３の開口部８とは、互いに対応している。すなわち、取付板材１の装置開口部２４は、支持部３の開口部８の前側に位置している。前述したように、装置開口部２４の大きさは、開口部８の大きさよりも小さい。従って、取付板材１は、支持部３の開口部８の一部を塞ぐように、支持部３に設けられる。モータ駆動装置４が取付板材１に固定された状態において、装置開口部２４は、装置開口部２４の大きさがフランジ１５の大きさよりも小さいので、フランジ１５によって塞がれる。モータ駆動装置４が支持部３に取り付けられた状態において、モータ駆動装置４の放熱部１６は、取付板材１の装置開口部２４及び支持部３の開口部８に通されている。従って、モータ駆動装置４の放熱部１６は、第２空間１０内に配置される。 The mounting plate 1 is fixed to the support 3 by the plate fixing portion 20, and the motor drive unit 4 is fixed to the mounting plate 1 by the device fixing portion 22, so that the motor drive unit 4 is detachably attached to the support 3. When the mounting plate 1 is fixed to the support 3, the device opening 24 of the mounting plate 1 and the opening 8 of the support 3 correspond to each other. That is, the device opening 24 of the mounting plate 1 is located in front of the opening 8 of the support 3. As described above, the size of the device opening 24 is smaller than the size of the opening 8. Therefore, the mounting plate 1 is provided on the support 3 so as to block a part of the opening 8 of the support 3. When the motor drive unit 4 is fixed to the mounting plate 1, the device opening 24 is blocked by the flange 15 because the size of the device opening 24 is smaller than the size of the flange 15. When the motor drive unit 4 is attached to the support unit 3, the heat dissipation unit 16 of the motor drive unit 4 passes through the device opening 24 of the mounting plate 1 and the opening 8 of the support unit 3. Therefore, the heat dissipation unit 16 of the motor drive unit 4 is disposed in the second space 10.
　第１実施形態の取付板材１の場合、取付板材１は、配置部２１を介して支持部３のねじ孔２５に板固定部２０がねじ込まれることで、支持部３に固定される。支持部３のねじ孔２５は、取付板材１を介して支持部３に固定されるモータ駆動装置４よりもサイズの大きいモータ駆動装置４を支持部３に取り付ける際に用いられていた。サイズの大きいモータ駆動装置４は、フランジ１５の貫通孔１９を介して支持部３のねじ孔２５に板固定部２０がねじ込まれることで、支持部３に直接に固定される。第１実施形態の取付板材１によれば、取付板材１を支持部３に固定する際に、モータ駆動装置４を支持部３に直接に取り付ける際に用いられていたねじ孔２５を利用している。 In the case of the mounting plate 1 of the first embodiment, the mounting plate 1 is fixed to the support 3 by screwing the plate fixing portion 20 into the screw hole 25 of the support 3 via the arrangement portion 21. The screw hole 25 of the support 3 was used when attaching a motor drive device 4 larger in size to the support 3 than the motor drive device 4 fixed to the support 3 via the mounting plate 1. The larger motor drive device 4 is fixed directly to the support 3 by screwing the plate fixing portion 20 into the screw hole 25 of the support 3 via the through hole 19 of the flange 15. According to the mounting plate 1 of the first embodiment, the screw hole 25 used when directly attaching the motor drive device 4 to the support 3 is used when fixing the mounting plate 1 to the support 3.
　第１実施形態の取付板材１の場合、装置開口部２４の大きさは、支持部３の開口部８の大きさ及びフランジ１５の大きさよりも小さい。従って、モータ駆動装置４が支持部３に固定された際、第１空間９と第２空間１０とは、連通されない。第１空間９と第２空間１０とが連通されないので、外部と連通する第２空間１０内の汚れた空気は、第１空間９内に流れ込まない。これにより、制御部１４が配置される第１空間９内を清浄に保つことができる。 In the case of the mounting plate 1 of the first embodiment, the size of the device opening 24 is smaller than the size of the opening 8 of the support portion 3 and the size of the flange 15. Therefore, when the motor drive device 4 is fixed to the support portion 3, the first space 9 and the second space 10 are not connected to each other. Since the first space 9 and the second space 10 are not connected to each other, dirty air in the second space 10, which is connected to the outside, does not flow into the first space 9. This makes it possible to keep the first space 9, in which the control portion 14 is located, clean.
　第１実施形態の取付板材１の場合、取付板材１は、銅製又はアルミ製であってもよい。この場合、制御部１４で生じた熱は、第２空間１０に逃げ易い。 In the case of the mounting plate 1 of the first embodiment, the mounting plate 1 may be made of copper or aluminum. In this case, the heat generated in the control unit 14 is likely to escape to the second space 10.
　次に、図５から図７を用いて、本発明の第２実施形態に係る取付板材について説明する。なお、第１実施形態で付した符号と同じ符号を有する構成部品は、その作用を同じにするので以下、説明を省略することがある。第２実施形態の取付板材１ａは、被固定部２３の構成が第１実施形態と異なる。 Next, a mounting plate according to a second embodiment of the present invention will be described with reference to Figures 5 to 7. Note that components having the same reference numerals as those in the first embodiment have the same functions, and therefore their description may be omitted below. The mounting plate 1a of the second embodiment differs from the first embodiment in the configuration of the fixed portion 23.
　第２実施形態の取付板材１ａには、第１実施形態の場合と同様にして、モータ駆動装置４が固定される。具体的には、装置固定部２２がモータ駆動装置４の貫通孔１９を介して被固定部２３にねじ込まれることで、取付板材１ａにモータ駆動装置４が取り付けられる。従って、モータ駆動装置４は、取付板材１ａの前面に取り付けられる。すなわち、取付板材１ａは、モータ駆動装置４が取り付けられる取付面２６を有している。 In the second embodiment, the motor drive unit 4 is fixed to the mounting plate 1a in the same manner as in the first embodiment. Specifically, the device fixing portion 22 is screwed into the fixed portion 23 through the through hole 19 of the motor drive unit 4, thereby mounting the motor drive unit 4 to the mounting plate 1a. Therefore, the motor drive unit 4 is mounted to the front surface of the mounting plate 1a. In other words, the mounting plate 1a has a mounting surface 26 to which the motor drive unit 4 is attached.
　取付板材１ａの被固定部２３は、取付面２６に開口した凹形状（有底の雌ねじ）である。被固定部２３は、取付板材１ａを貫通していない。そのため、取付板材１ａは、被固定部２３が貫通しない程度の厚さを有している。典型的には、取付板材１ａの厚さは、第１実施形態の取付板材１の厚さよりも大きい。 The fixed portion 23 of the mounting plate 1a is a concave shape (bottomed female thread) that opens to the mounting surface 26. The fixed portion 23 does not penetrate the mounting plate 1a. Therefore, the mounting plate 1a has a thickness that does not allow the fixed portion 23 to penetrate. Typically, the thickness of the mounting plate 1a is greater than the thickness of the mounting plate 1 of the first embodiment.
　４つの被固定部２３のうち、装置開口部２４の上側に位置する２つの被固定部２３，２３は、取付板材１ａの上部に位置する２つの配置部２１，２１と横方向に並んで配置される。装置開口部２４の上側に位置する２つの被固定部２３，２３は、取付板材１ａの上部に位置する２つの配置部２１，２１の内側に配置される。４つの被固定部２３のうち、装置開口部２４の下側に位置する２つの被固定部２３，２３は、取付板材１ａの下部に位置する２つの配置部２１，２１と横方向に並んで配置される。装置開口部２４の下側に位置する２つの被固定部２３，２３は、取付板材１ａの下部に位置する２つの配置部２１，２１の内側に配置される。 Of the four fixed parts 23, the two fixed parts 23, 23 located above the device opening 24 are arranged side by side with the two placement parts 21, 21 located at the top of the mounting plate 1a. The two fixed parts 23, 23 located above the device opening 24 are arranged inside the two placement parts 21, 21 located at the top of the mounting plate 1a. Of the four fixed parts 23, the two fixed parts 23, 23 located below the device opening 24 are arranged side by side with the two placement parts 21, 21 located at the bottom of the mounting plate 1a. The two fixed parts 23, 23 located below the device opening 24 are arranged inside the two placement parts 21, 21 located at the bottom of the mounting plate 1a.
　取付板材１ａの装置開口部２４の大きさは、支持部３の開口部８の大きさよりも小さい。具体的には、装置開口部２４の上下長さは、支持部３の開口部８の上下長さとほぼ同じ大きさであり、装置開口部２４の左右長さは、支持部３の開口部８の左右長さよりも小さい。装置開口部２４の大きさは、モータ駆動装置４のフランジ１５の大きさよりも小さい。具体的には、装置開口部２４の上下長さは、フランジ１５の上下長さよりも小さく、装置開口部２４の左右長さは、フランジ１５の左右長さよりも小さい。 The size of the device opening 24 in the mounting plate 1a is smaller than the size of the opening 8 in the support section 3. Specifically, the vertical length of the device opening 24 is approximately the same as the vertical length of the opening 8 in the support section 3, and the left-right length of the device opening 24 is smaller than the left-right length of the opening 8 in the support section 3. The size of the device opening 24 is smaller than the size of the flange 15 of the motor drive device 4. Specifically, the vertical length of the device opening 24 is smaller than the vertical length of the flange 15, and the left-right length of the device opening 24 is smaller than the left-right length of the flange 15.
　このような構成の取付板材１ａは、第１実施形態の取付板材１と同様にして、支持部３に固定される。具体的には、板固定部２０が取付板材１ａの配置部２１を介してねじ孔２５にねじ込まれることで、支持部３に取付板材１ａが取り付けられる。取付板材１ａが支持部３に固定された状態において、取付板材１ａの装置開口部２４と支持部３の開口部８とは、互いに対応している。すなわち、取付板材１ａの装置開口部２４は、支持部３の開口部８の前側に位置している。前述したように、装置開口部２４の上下長さは、支持部３の開口部８の上下長さとほぼ同じ大きさであり、装置開口部２４の左右長さは、支持部３の開口部８の左右長さよりも小さい。従って、取付板材１ａは、支持部３の開口部８の左右両端部を塞ぐように、支持部３に設けられる。このように、取付板材１ａは、支持部３の開口部８の一部を塞ぐように、支持部３に設けられる。 The mounting plate 1a having such a configuration is fixed to the support 3 in the same manner as the mounting plate 1 of the first embodiment. Specifically, the plate fixing portion 20 is screwed into the screw hole 25 via the arrangement portion 21 of the mounting plate 1a, thereby mounting the mounting plate 1a to the support 3. When the mounting plate 1a is fixed to the support 3, the device opening 24 of the mounting plate 1a and the opening 8 of the support 3 correspond to each other. That is, the device opening 24 of the mounting plate 1a is located in front of the opening 8 of the support 3. As described above, the vertical length of the device opening 24 is approximately the same as the vertical length of the opening 8 of the support 3, and the left-right length of the device opening 24 is smaller than the left-right length of the opening 8 of the support 3. Therefore, the mounting plate 1a is provided on the support 3 so as to block both the left and right ends of the opening 8 of the support 3. In this way, the mounting plate 1a is provided on the support 3 so as to block a part of the opening 8 of the support 3.
　第２実施形態の取付板材１ａの場合、４つの被固定部２３のうち、装置開口部２４の上側に位置する２つの被固定部２３，２３は、取付板材１ａの上部に位置する２つの配置部２１，２１と横方向に並んで配置される。４つの被固定部２３のうち、装置開口部２４の下側に位置する２つの被固定部２３，２３は、取付板材１ａの下部に位置する２つの配置部２１，２１と横方向に並んで配置される。従って、取付板材１ａが支持部３に固定された状態において、被固定部２３は、支持部３の前面の前側に配置される。この場合、被固定部が取付板材を貫通していると、被固定部にねじ込まれた装置固定部２２は、支持部３の前面に接触するおそれがある。装置固定部２２が支持部３の前面に接触した場合、装置固定部２２は、モータ駆動装置４を取付板材に固定できるまでねじ込むことができないおそれがある。 In the case of the mounting plate 1a of the second embodiment, of the four fixed parts 23, the two fixed parts 23, 23 located above the device opening 24 are arranged side by side with the two arrangement parts 21, 21 located at the top of the mounting plate 1a. Of the four fixed parts 23, the two fixed parts 23, 23 located below the device opening 24 are arranged side by side with the two arrangement parts 21, 21 located at the bottom of the mounting plate 1a. Therefore, when the mounting plate 1a is fixed to the support 3, the fixed parts 23 are arranged in front of the front surface of the support 3. In this case, if the fixed parts penetrate the mounting plate, the device fixing part 22 screwed into the fixed parts may come into contact with the front surface of the support 3. If the device fixing part 22 comes into contact with the front surface of the support 3, the device fixing part 22 may not be screwed in enough to fix the motor drive unit 4 to the mounting plate.
　これに対し、第２実施形態の取付板材１ａでは、被固定部２３は、取付板材１ａを貫通していない。従って、第２実施形態の取付板材１ａによれば、上述した問題が生じないので、装置固定部２２は、モータ駆動装置４を取付板材１ａに固定できるまでねじ込むことができる。 In contrast, in the mounting plate 1a of the second embodiment, the fixed portion 23 does not penetrate the mounting plate 1a. Therefore, with the mounting plate 1a of the second embodiment, the above-mentioned problem does not occur, and the device fixing portion 22 can be screwed in until the motor drive device 4 can be fixed to the mounting plate 1a.
　次に、図８から図１０を用いて、本発明の第３実施形態に係る取付板材について説明する。なお、第１実施形態で付した符号と同じ符号を有する構成部品は、その作用を同じにするので以下、説明を省略することがある。第３実施形態の取付板材１ｂは、被固定部２３の構成が第１実施形態と異なる。 Next, a mounting plate according to a third embodiment of the present invention will be described with reference to Figures 8 to 10. Note that components having the same reference numerals as those in the first embodiment have the same functions, and therefore their description may be omitted below. The mounting plate 1b of the third embodiment differs from the first embodiment in the configuration of the fixed portion 23.
　第３実施形態の取付板材１ｂの被固定部２３は、外周面にねじ２７が形成されたねじ棒である。被固定部２３は、取付板材１ｂから前方に突出している。被固定部２３がねじ棒であるので、装置固定部２２は、被固定部２３にねじ込まれるナットである。 The fixed part 23 of the mounting plate 1b in the third embodiment is a threaded rod with threads 27 formed on the outer circumferential surface. The fixed part 23 protrudes forward from the mounting plate 1b. Because the fixed part 23 is a threaded rod, the device fixing part 22 is a nut that is screwed into the fixed part 23.
　４つの被固定部２３のうち、装置開口部２４の上側に位置する２つの被固定部２３，２３は、取付板材１ｂの上部に位置する２つの配置部２１，２１と横方向（左右方向）に並んで配置される。装置開口部２４の上側に位置する２つの被固定部２３，２３は、取付板材１ｂの上部に位置する２つの配置部２１，２１の内側に配置される。４つの被固定部２３のうち、装置開口部２４の下側に位置する２つの被固定部２３，２３は、取付板材１ｂの下部に位置する２つの配置部２１，２１と横方向に並んで配置される。装置開口部２４の下側に位置する２つの被固定部２３，２３は、取付板材１ｂの下部に位置する２つの配置部２１，２１の内側に配置される。 Of the four fixed parts 23, the two fixed parts 23, 23 located above the device opening 24 are arranged side by side (left and right) with the two placement parts 21, 21 located at the top of the mounting plate 1b. The two fixed parts 23, 23 located above the device opening 24 are arranged inside the two placement parts 21, 21 located at the top of the mounting plate 1b. Of the four fixed parts 23, the two fixed parts 23, 23 located below the device opening 24 are arranged side by side with the two placement parts 21, 21 located at the bottom of the mounting plate 1b. The two fixed parts 23, 23 located below the device opening 24 are arranged inside the two placement parts 21, 21 located at the bottom of the mounting plate 1b.
　取付板材１ｂの装置開口部２４の大きさは、支持部３の開口部８の大きさよりも小さい。具体的には、装置開口部２４の上下長さは、支持部３の開口部８の上下長さとほぼ同じ大きさであり、装置開口部２４の左右長さは、支持部３の開口部８の左右長さよりも小さい。装置開口部２４の大きさは、モータ駆動装置４のフランジ１５の大きさよりも小さい。具体的には、装置開口部２４の上下長さは、フランジ１５の上下長さよりも小さく、装置開口部２４の左右長さは、フランジ１５の左右長さよりも小さい。 The size of the device opening 24 in the mounting plate 1b is smaller than the size of the opening 8 in the support section 3. Specifically, the vertical length of the device opening 24 is approximately the same as the vertical length of the opening 8 in the support section 3, and the left-right length of the device opening 24 is smaller than the left-right length of the opening 8 in the support section 3. The size of the device opening 24 is smaller than the size of the flange 15 of the motor drive device 4. Specifically, the vertical length of the device opening 24 is smaller than the vertical length of the flange 15, and the left-right length of the device opening 24 is smaller than the left-right length of the flange 15.
　取付板材１ｂにモータ駆動装置４を固定するには、フランジ１５の貫通孔１９に被固定部２３が通された状態で、被固定部２３に装置固定部２２をねじ込めばよい。これにより、モータ駆動装置４は、取付板材１ｂに着脱可能に固定される。 To fix the motor drive unit 4 to the mounting plate 1b, the device fixing part 22 is screwed into the fixed part 23 with the fixed part 23 passing through the through hole 19 of the flange 15. This allows the motor drive unit 4 to be removably fixed to the mounting plate 1b.
　第３実施形態では、板固定部２０は、ねじであり、配置部２１は、板固定部２０が貫通する貫通孔である。このような構成であるので、取付板材１ｂは、第１実施形態の取付板材１と同様にして、支持部３に固定される。具体的には、板固定部２０が取付板材１ｂの配置部２１を介してねじ孔２５にねじ込まれることで、支持部３に取付板材１ｂが取り付けられる。取付板材１ｂが支持部３に固定された状態において、取付板材１ｂの装置開口部２４と支持部３の開口部８とは、互いに対応している。すなわち、取付板材１ｂの装置開口部２４は、支持部３の開口部８の前側に位置している。前述したように、装置開口部２４の上下長さは、支持部３の開口部８の上下長さとほぼ同じ大きさであり、装置開口部２４の左右長さは、支持部３の開口部８の左右長さよりも小さい。従って、取付板材１ｂは、支持部３の開口部８の左右両端部を塞ぐように、支持部３に設けられる。このように、取付板材１ｂは、支持部３の開口部８の一部を塞ぐように、支持部３に設けられる。 In the third embodiment, the plate fixing portion 20 is a screw, and the arrangement portion 21 is a through hole through which the plate fixing portion 20 passes. With this configuration, the mounting plate 1b is fixed to the support portion 3 in the same manner as the mounting plate 1 of the first embodiment. Specifically, the plate fixing portion 20 is screwed into the screw hole 25 via the arrangement portion 21 of the mounting plate 1b, thereby attaching the mounting plate 1b to the support portion 3. When the mounting plate 1b is fixed to the support portion 3, the device opening 24 of the mounting plate 1b and the opening 8 of the support portion 3 correspond to each other. That is, the device opening 24 of the mounting plate 1b is located in front of the opening 8 of the support portion 3. As described above, the vertical length of the device opening 24 is approximately the same as the vertical length of the opening 8 of the support portion 3, and the left-right length of the device opening 24 is smaller than the left-right length of the opening 8 of the support portion 3. Therefore, the mounting plate material 1b is provided on the support part 3 so as to cover both the left and right ends of the opening 8 of the support part 3. In this way, the mounting plate material 1b is provided on the support part 3 so as to cover a portion of the opening 8 of the support part 3.
　第３実施形態の取付板材１ｂの場合、被固定部２３は、外周面にねじが形成されたねじ棒である。従って、第３実施形態の取付板材１ｂによれば、被固定部２３がフランジ１５に通されるので、モータ駆動装置４を取付板材１ｂに固定する際に、モータ駆動装置４を取付板材１ｂに対して位置決めできる。 In the case of the mounting plate 1b of the third embodiment, the fixed portion 23 is a threaded rod with a screw formed on the outer circumferential surface. Therefore, according to the mounting plate 1b of the third embodiment, the fixed portion 23 is passed through the flange 15, so that when the motor drive unit 4 is fixed to the mounting plate 1b, the motor drive unit 4 can be positioned relative to the mounting plate 1b.
　次に、図１１から図１３を用いて、本発明の第４実施形態に係る取付板材について説明する。なお、第１実施形態で付した符号と同じ符号を有する構成部品は、その作用を同じにするので以下、説明を省略することがある。第４実施形態の取付板材１ｃは、装置開口部２４を備えない点が第１実施形態と異なる。具体的には、取付板材１ｃは、支持部３に取付板材１ｃを固定する板固定部２０が配置される配置部２１と、取付板材１ｃにモータ駆動装置４を固定する装置固定部２２が固定される被固定部２３とを備える。一方、取付板材１ｃは、モータ駆動装置４の一部が通される装置開口部２４を備えない。 Next, a mounting plate according to a fourth embodiment of the present invention will be described with reference to Figures 11 to 13. Note that components having the same reference numerals as those in the first embodiment have the same functions, and therefore their description may be omitted below. The mounting plate 1c of the fourth embodiment differs from the first embodiment in that it does not have an apparatus opening 24. Specifically, the mounting plate 1c has a placement section 21 in which a plate fixing section 20 that fixes the mounting plate 1c to the support section 3 is placed, and a fixed section 23 to which a device fixing section 22 that fixes the motor drive device 4 to the mounting plate 1c is fixed. On the other hand, the mounting plate 1c does not have an apparatus opening 24 through which part of the motor drive device 4 passes.
　板固定部２０は、ねじ（雄ねじ）であり、配置部２１は、板固定部２０が貫通する貫通孔である。このような構成であるので、取付板材１ｃは、第１実施形態の取付板材１と同様にして、支持部３に固定される。具体的には、板固定部２０が取付板材１ｃの配置部２１を介してねじ孔２５にねじ込まれることで、支持部３に取付板材１ｃが取り付けられる。支持部３に取付板材１ｃが固定された状態において、取付板材１ｃは、装置開口部２４を備えないので、支持部３の開口部８の全体を塞ぐ。 The plate fixing portion 20 is a screw (male screw), and the arrangement portion 21 is a through hole through which the plate fixing portion 20 passes. With this configuration, the mounting plate 1c is fixed to the support portion 3 in the same manner as the mounting plate 1 of the first embodiment. Specifically, the plate fixing portion 20 is screwed into the screw hole 25 via the arrangement portion 21 of the mounting plate 1c, thereby attaching the mounting plate 1c to the support portion 3. When the mounting plate 1c is fixed to the support portion 3, the mounting plate 1c does not have an apparatus opening 24, and therefore completely blocks the opening 8 of the support portion 3.
　取付板材１ｃに固定されるモータ駆動装置４は、第１実施形態で用いられるモータ駆動装置４と構成が異なる。具体的には、モータ駆動装置４は、放熱部１６を有していない。モータ駆動装置４は、装置固定部２２によって取付板材１ｃの前面に着脱可能に固定される。装置固定部２２は、ねじであり、被固定部２３は、装置固定部２２がねじ込まれるねじ孔である。このような構成であるので、装置固定部２２がフランジ１５の貫通孔１９を介して被固定部２３にねじ込まれることで、取付板材１ｃにモータ駆動装置４が取り付けられる。 The motor drive device 4 fixed to the mounting plate 1c has a different configuration from the motor drive device 4 used in the first embodiment. Specifically, the motor drive device 4 does not have a heat dissipation section 16. The motor drive device 4 is removably fixed to the front surface of the mounting plate 1c by a device fixing section 22. The device fixing section 22 is a screw, and the fixed section 23 is a screw hole into which the device fixing section 22 is screwed. With this configuration, the motor drive device 4 is attached to the mounting plate 1c by screwing the device fixing section 22 into the fixed section 23 through the through hole 19 of the flange 15.
　第４実施形態の取付板材１ｃの場合、取付板材１ｃは、装置開口部２４を有していない。従って、第４実施形態の取付板材１ｃによれば、放熱部１６を有していないモータ駆動装置４が固定される取付板材１ｃを容易に製造することができる。 In the case of the mounting plate 1c of the fourth embodiment, the mounting plate 1c does not have a device opening 24. Therefore, according to the mounting plate 1c of the fourth embodiment, it is possible to easily manufacture a mounting plate 1c to which a motor drive device 4 that does not have a heat dissipation section 16 is fixed.
　次に、図１４から図１６を用いて、本発明の第５実施形態に係る取付板材について説明する。なお、第１実施形態で付した符号と同じ符号を有する構成部品は、その作用を同じにするので以下、説明を省略することがある。第５実施形態の取付板材１ｄは、取付板材１ｄを補強する構成を有する点が第１実施形態と異なる。 Next, a mounting plate according to a fifth embodiment of the present invention will be described with reference to Figures 14 to 16. Note that components having the same reference numerals as those in the first embodiment have the same functions, and therefore their description may be omitted below. The mounting plate 1d of the fifth embodiment differs from the first embodiment in that it has a structure that reinforces the mounting plate 1d.
　第５実施形態の取付板材１ｄは、取付板材１ｄを補強するリブ２９を備える。図示例では、リブ２９は、正面から見た場合、略四角形の枠状である。具体的には、リブ２９は、取付板材１ｄの上端部から前方に突出する上枠部３０と、取付板材１ｄの下端部から前方に突出する下枠部３１と、取付板材１ｄの左端部から前方に突出する左枠部３２と、取付板材１ｄの右端部から前方に突出する右枠部３３とを有している。すなわち、取付板材１ｄは、前方に開口する箱状である。なお、リブ２９は、曲げ加工、溶接又は絞り加工などによって形成される。 The mounting plate 1d of the fifth embodiment includes a rib 29 that reinforces the mounting plate 1d. In the illustrated example, the rib 29 is in the shape of a substantially rectangular frame when viewed from the front. Specifically, the rib 29 has an upper frame portion 30 that protrudes forward from the upper end of the mounting plate 1d, a lower frame portion 31 that protrudes forward from the lower end of the mounting plate 1d, a left frame portion 32 that protrudes forward from the left end of the mounting plate 1d, and a right frame portion 33 that protrudes forward from the right end of the mounting plate 1d. In other words, the mounting plate 1d is box-shaped and opens forward. The rib 29 is formed by bending, welding, drawing, or the like.
　取付板材１ｄは、第１実施形態の取付板材１と同様にして、支持部３に固定される。具体的には、板固定部２０が取付板材１ｄの配置部２１を介してねじ孔２５にねじ込まれることで、支持部３に取付板材１ｄが取り付けられる。取付板材１ｄには、第１実施形態の取付板材１と同様にして、モータ駆動装置４が固定される。具体的には、装置固定部２２がモータ駆動装置４の貫通孔１９を介して被固定部２３にねじ込まれることで、取付板材１ｄにモータ駆動装置４が取り付けられる。 The mounting plate 1d is fixed to the support 3 in the same manner as the mounting plate 1 of the first embodiment. Specifically, the plate fixing portion 20 is screwed into the screw hole 25 via the arrangement portion 21 of the mounting plate 1d, thereby attaching the mounting plate 1d to the support 3. The motor drive device 4 is fixed to the mounting plate 1d in the same manner as the mounting plate 1 of the first embodiment. Specifically, the device fixing portion 22 is screwed into the fixed portion 23 via the through hole 19 of the motor drive device 4, thereby attaching the motor drive device 4 to the mounting plate 1d.
　第５実施形態の取付板材１ｄの場合、取付板材１ｄは、枠状のリブ２９を備える。従って、第５実施形態の取付板材１ｄによれば、取付板材１ｄの強度を補強することができる。 In the case of the mounting plate 1d of the fifth embodiment, the mounting plate 1d has a frame-shaped rib 29. Therefore, according to the mounting plate 1d of the fifth embodiment, the strength of the mounting plate 1d can be reinforced.
　次に、図１７から図１９を用いて、本発明の第６実施形態に係る取付板材について説明する。なお、第１実施形態で付した符号と同じ符号を有する構成部品は、その作用を同じにするので以下、説明を省略することがある。第６実施形態の取付板材１ｅは、複数のモータ駆動装置４が固定される点が第１実施形態と異なる。 Next, a mounting plate according to a sixth embodiment of the present invention will be described with reference to Figures 17 to 19. Note that components having the same reference numerals as those in the first embodiment have the same functions, and therefore their description may be omitted below. The mounting plate 1e of the sixth embodiment differs from the first embodiment in that multiple motor drive devices 4 are fixed to it.
　第６実施形態の取付板材１ｅは、１つの取付板材１ｅにつき、複数の装置開口部２４を備える。複数の装置開口部２４は、横方向（左右方向）に並んで配置される。図示例では、取付板材１ｅの装置開口部２４の数は、３つとされるが、これに限定されるものではなく、２つであってもよいし、４つ以上であってもよい。 The mounting plate 1e of the sixth embodiment has multiple device openings 24 per mounting plate 1e. The multiple device openings 24 are arranged side by side in the horizontal direction (left-right direction). In the illustrated example, the number of device openings 24 on the mounting plate 1e is three, but this is not limited to this and may be two, or four or more.
　取付板材１ｅは、複数の配置部２１を備える。複数の配置部２１は、支持部３のねじ孔２５と対応する位置に配置される。なお、配置部２１は、取付板材１ｅの四隅にのみ配置してもよい。取付板材１ｅは、板固定部２０が取付板材１ｅの配置部２１を介してねじ孔２５にねじ込まれることで、支持部３に取り付けられる。従って、取付板材１ｅは、板固定部２０によって支持部３の前面に着脱可能に固定される。 The mounting plate 1e has a plurality of positioning portions 21. The plurality of positioning portions 21 are arranged at positions corresponding to the screw holes 25 of the support portion 3. The positioning portions 21 may be arranged only at the four corners of the mounting plate 1e. The mounting plate 1e is attached to the support portion 3 by screwing the plate fixing portions 20 into the screw holes 25 via the positioning portions 21 of the mounting plate 1e. Therefore, the mounting plate 1e is removably fixed to the front surface of the support portion 3 by the plate fixing portions 20.
　取付板材１ｅには、複数の装置開口部２４それぞれを閉じるようにして、複数のモータ駆動装置４が固定される。各モータ駆動装置４は、装置固定部２２がモータ駆動装置４の貫通孔１９を介して被固定部２３にねじ込まれることで、取付板材１ｅに取り付けられる。従って、モータ駆動装置４は、装置固定部２２によって取付板材１ｅの前面に着脱可能に固定される。 A number of motor drive units 4 are fixed to the mounting plate 1e so as to close each of the multiple device openings 24. Each motor drive unit 4 is attached to the mounting plate 1e by screwing the device fixing portion 22 into the fixed portion 23 through the through hole 19 of the motor drive unit 4. Thus, the motor drive units 4 are removably fixed to the front surface of the mounting plate 1e by the device fixing portion 22.
　第６実施形態の取付板材１ｅの場合、取付板材１ｅは、１つの取付板材１ｅにつき、複数の装置開口部２４を有している。従って、第６実施形態の取付板材１ｅによれば、取付板材１ｅに複数のモータ駆動装置４を容易に固定することができる。 In the case of the mounting plate 1e of the sixth embodiment, each mounting plate 1e has multiple device openings 24. Therefore, according to the mounting plate 1e of the sixth embodiment, multiple motor drive devices 4 can be easily fixed to the mounting plate 1e.
　複数のモータ駆動装置４が横方向に並んでいる場合、隣接するモータ駆動装置４，４同士は、ケーブルなどで接続される。従って、第６実施形態の取付板材１ｅは、複数のモータ駆動装置４を支持部３に実装する際に好適に用いられる。 When multiple motor drive units 4 are arranged side by side, adjacent motor drive units 4, 4 are connected to each other by cables or the like. Therefore, the mounting plate material 1e of the sixth embodiment is preferably used when mounting multiple motor drive units 4 to the support portion 3.
　次に、図２０及び図２１を用いて、本発明の一実施形態に係るモータ駆動装置の取付構造について説明する。なお、第１実施形態で付した符号と同じ符号を有する構成部品は、その作用を同じにするので以下、説明を省略することがある。 Next, the mounting structure of a motor drive device according to one embodiment of the present invention will be described with reference to Figures 20 and 21. Note that components having the same reference numerals as those in the first embodiment have the same functions, and therefore their description may be omitted below.
　モータ駆動装置４の取付構造は、取付板材１と、取付板材１と支持部３との間の隙間、及びモータ駆動装置４と取付板材１との間の隙間を封止する封止材３４とを備える。モータ駆動装置４の取付構造に適用される取付板材１は、第１実施形態の取付板材１と同様の構成である。取付板材１が固定される支持部３の構成、及び取付板材１に固定されるモータ駆動装置４の構成は、第１実施形態の場合と同様である。従って、取付板材１は、第１実施形態の取付板材１と同様にして、支持部３に固定される。具体的には、板固定部２０が取付板材１の配置部２１を介してねじ孔２５にねじ込まれることで、支持部３に取付板材１が取り付けられる。取付板材１には、第１実施形態の取付板材１と同様にして、モータ駆動装置４が固定される。具体的には、装置固定部２２がモータ駆動装置４の貫通孔１９を介して被固定部２３にねじ込まれることで、取付板材１にモータ駆動装置４が取り付けられる。 The mounting structure of the motor drive device 4 includes a mounting plate 1 and a sealant 34 that seals the gap between the mounting plate 1 and the support 3, and the gap between the motor drive device 4 and the mounting plate 1. The mounting plate 1 applied to the mounting structure of the motor drive device 4 has the same configuration as the mounting plate 1 of the first embodiment. The configuration of the support 3 to which the mounting plate 1 is fixed, and the configuration of the motor drive device 4 fixed to the mounting plate 1 are the same as those of the first embodiment. Therefore, the mounting plate 1 is fixed to the support 3 in the same manner as the mounting plate 1 of the first embodiment. Specifically, the plate fixing portion 20 is screwed into the screw hole 25 through the arrangement portion 21 of the mounting plate 1, thereby attaching the mounting plate 1 to the support 3. The motor drive device 4 is fixed to the mounting plate 1 in the same manner as the mounting plate 1 of the first embodiment. Specifically, the device fixing portion 22 is screwed into the fixed portion 23 through the through hole 19 of the motor drive device 4, thereby attaching the motor drive device 4 to the mounting plate 1.
　モータ駆動装置４が収容される筐体５の構成は、第１実施形態の場合と同様である。従って、モータ駆動装置４が支持部３に固定された状態において、モータ駆動装置４の制御部１４は、第１空間９内に配置され、モータ駆動装置４の放熱部１６は、第２空間１０内に配置される。 The configuration of the housing 5 in which the motor drive device 4 is housed is the same as in the first embodiment. Therefore, when the motor drive device 4 is fixed to the support part 3, the control part 14 of the motor drive device 4 is disposed in the first space 9, and the heat dissipation part 16 of the motor drive device 4 is disposed in the second space 10.
　封止材３４，３４は、正面から見た場合、略四角形の枠状である。封止材３４は、モータ駆動装置４が支持部３に固定された状態において、取付板材１と支持部３との間の隙間を封止する。具体的には、封止材３４は、取付板材１と支持部３との間で支持部３の開口部８を取り囲んで、取付板材１と支持部３との間の隙間を封止する。封止材３４は、モータ駆動装置４が支持部３に固定された状態において、モータ駆動装置４と取付板材１との間を封止する。具体的には、封止材３４は、モータ駆動装置４のフランジ１５と取付板材１との間で取付板材１の装置開口部２４を取り囲んで、モータ駆動装置４のフランジ１５と取付板材１との間の隙間を封止する。 When viewed from the front, the sealing materials 34, 34 are in the shape of a substantially rectangular frame. The sealing material 34 seals the gap between the mounting plate 1 and the support 3 when the motor drive unit 4 is fixed to the support 3. Specifically, the sealing material 34 surrounds the opening 8 of the support 3 between the mounting plate 1 and the support 3, sealing the gap between the mounting plate 1 and the support 3. When the motor drive unit 4 is fixed to the support 3, the sealing material 34 seals the gap between the motor drive unit 4 and the mounting plate 1. Specifically, the sealing material 34 surrounds the device opening 24 of the mounting plate 1 between the flange 15 of the motor drive unit 4 and the mounting plate 1, sealing the gap between the flange 15 of the motor drive unit 4 and the mounting plate 1.
　なお、図示例では、取付板材１と支持部３との間の隙間、及びモータ駆動装置４と取付板材１との間の隙間が封止材３４によって封止されたが、これに限定されるものではない。具体的には、取付板材１と支持部３との間の隙間、及びモータ駆動装置４と取付板材１との間の隙間のうち、一方の隙間が封止材３４によって封止され、他方の隙間が封止材３４によって封止されていなくてもよい。すなわち、封止材３４は、取付板材１と支持部３との間の隙間、又はモータ駆動装置４と取付板材１との間の隙間の少なくとも一方を封止すればよい。 In the illustrated example, the gap between the mounting plate 1 and the support 3, and the gap between the motor drive unit 4 and the mounting plate 1 are sealed with the sealant 34, but this is not limited to the above. Specifically, it is acceptable for one of the gaps between the mounting plate 1 and the support 3 and the gap between the motor drive unit 4 and the mounting plate 1 to be sealed with the sealant 34, and for the other gap not to be sealed with the sealant 34. In other words, it is sufficient for the sealant 34 to seal at least one of the gaps between the mounting plate 1 and the support 3, and the gap between the motor drive unit 4 and the mounting plate 1.
　本実施形態の取付構造の場合、封止材３４は、取付板材１と支持部３との間の隙間、及びモータ駆動装置４と取付板材１との間の隙間を封止する。従って、本実施形態の取付構造によれば、第２空間１０内の汚れた空気が第１空間９内に流れ込むのをより確実に防止することができる。 In the mounting structure of this embodiment, the sealant 34 seals the gap between the mounting plate 1 and the support 3, and the gap between the motor drive unit 4 and the mounting plate 1. Therefore, the mounting structure of this embodiment can more reliably prevent dirty air in the second space 10 from flowing into the first space 9.
　以上説明した少なくとも一つの実施形態によれば、モータ駆動装置４は、前述した構成の取付板材１を介して、制御盤２の支持部３に固定される。従って、制御盤２の支持部３の構成はそのままで、制御盤２の支持部３に小型化されたモータ駆動装置４を容易に取り付けることができる取付板材１、及びその取付板材１を備える取付構造を提供することができる。 According to at least one of the embodiments described above, the motor drive unit 4 is fixed to the support portion 3 of the control panel 2 via the mounting plate 1 having the above-described configuration. Therefore, it is possible to provide a mounting plate 1 that can easily mount a miniaturized motor drive unit 4 to the support portion 3 of the control panel 2 while leaving the configuration of the support portion 3 of the control panel 2 unchanged, and a mounting structure that includes the mounting plate 1.
　本開示について詳述したが、本開示は上述した個々の実施形態に限定されるものではない。これらの実施形態は、本開示の要旨を逸脱しない範囲で、または、特許請求の範囲に記載された内容とその均等物から導き出される本開示の趣旨を逸脱しない範囲で、種々の追加、置き換え、変更、部分的削除等が可能である。また、これらの実施形態は、組み合わせて実施することもできる。例えば、上述した実施形態において、各動作の順序や各処理の順序は、一例として示したものであり、これらに限定されるものではない。また、上述した実施形態の説明に数値又は数式が用いられている場合も同様である。 Although the present disclosure has been described in detail, the present disclosure is not limited to the individual embodiments described above.

For example, in the above-mentioned embodiments, the order of each operation and the order of each process are shown as examples, and are not limited to these. The same applies when numerical values or formulas are used to explain the above-mentioned embodiments.
　例えば、第２実施形態の取付板材１ａ、第３実施形態の取付板材１ｂ、第４実施形態の取付板材１ｃ、及び第６実施形態の取付板材１ｅは、取付板材を補強するリブを備えていてもよい。例えば、第２実施形態の取付板材１ａ、第３実施形態の取付板材１ｂ、第４実施形態の取付板材１ｃ、及び第５実施形態の取付板材１ｄは、１つの取付板材につき、複数のモータ駆動装置４が固定されてもよい。この場合は、取付板材は、複数の装置開口部を有している。例えば、第２実施形態の取付板材１ａが適用される取付構造、第３実施形態の取付板材１ｂが適用される取付構造、第５実施形態の取付板材１ｄが適用される取付構造、及び第６実施形態の取付板材１ｅが適用される取付構造において、封止材が用いられてもよい。 For example, the mounting plate 1a of the second embodiment, the mounting plate 1b of the third embodiment, the mounting plate 1c of the fourth embodiment, and the mounting plate 1e of the sixth embodiment may have ribs that reinforce the mounting plate. For example, the mounting plate 1a of the second embodiment, the mounting plate 1b of the third embodiment, the mounting plate 1c of the fourth embodiment, and the mounting plate 1d of the fifth embodiment may have multiple motor drive devices 4 fixed to each mounting plate. In this case, the mounting plate has multiple device openings. For example, a sealing material may be used in the mounting structure to which the mounting plate 1a of the second embodiment is applied, the mounting structure to which the mounting plate 1b of the third embodiment is applied, the mounting structure to which the mounting plate 1d of the fifth embodiment is applied, and the mounting structure to which the mounting plate 1e of the sixth embodiment is applied.
