実施の形態１．
本発明の実施の形態１による３相２重化モータを示す図１〜図３において、電磁鋼板を積層して形成されたステータ（固定子）鉄心１にはティース２が１２個設けられており、図示しない樹脂製のインシュレータを介して巻線３は、Ｕ相、Ｖ相、Ｗ相から成る３相巻線を１群として２群分（Ｕ１、Ｕ２；Ｖ１、Ｖ２；Ｗ１、Ｗ２）備えることにより、Δ結線の３相２重化モータを構成している。各群の各相の巻線は、隣り合う２つのティース２を１組として連続して巻回され、Ｕ１相は、巻線Ｕ１＋とＵ１−、Ｖ１相は巻線Ｖ１＋とＶ１−、Ｗ１相は巻線Ｗ１＋とＷ１−、Ｕ２相は巻線Ｕ２＋とＵ２−、Ｖ２相は巻線Ｖ２＋とＶ２−、そして、Ｗ２相は巻線Ｗ２＋とＷ２−を備えている。 Embodiment 1 FIG.
1 to 3 showing a three-phase duplex motor according to Embodiment 1 of the present invention, 12 teeth 2 are provided on a stator (stator) core 1 formed by laminating electromagnetic steel plates. The winding 3 is provided with two groups (U1, U2; V1, V2; W1, W2) of three-phase windings composed of a U phase, a V phase, and a W phase through a resin insulator (not shown). Thus, a three-phase duplex motor with Δ connection is configured. The windings of each phase of each group are wound continuously with two adjacent teeth 2 as one set. The U1 phase is windings U1 + and U1-, the V1 phase is windings V1 + and V1-, and the W1 phase. Includes windings W1 + and W1-, the U2 phase includes windings U2 + and U2-, the V2 phase includes windings V2 + and V2-, and the W2 phase includes windings W2 + and W2-.

すなわち、各組の巻線同士は、直列に接続されており、巻線の巻回方向は互いに逆方向になっていて、巻線の配置は、図１の右側から、Ｕ１＋、Ｕ１−、Ｖ１−、Ｖ１＋、Ｗ１＋、Ｗ１−、Ｕ２−、Ｕ２＋、Ｖ２＋、Ｖ２−、Ｗ２−、Ｗ２＋の順になっており、Ｕ１＋とＵ１−、Ｖ１−とＶ１＋、Ｗ１＋とＷ１−、Ｕ２−とＵ２＋、Ｖ２＋とＶ２−、Ｗ２−とＷ２＋はそれぞれ互いに逆方向に巻回され、且つ直列に接続されている。なお、このＵ＋、Ｕ−、Ｖ−、Ｖ＋、Ｗ＋、Ｗ−、Ｕ−、Ｕ＋、Ｖ＋、Ｖ−、Ｗ−、Ｗ＋の巻線配置は、１０極１２スロット方式用のものである。   That is, the windings of each set are connected in series, and the winding directions of the windings are opposite to each other. The windings are arranged from the right side of FIG. 1 from U1 +, U1-, V1. -, V1 +, W1 +, W1-, U2-, U2 +, V2 +, V2-, W2-, W2 + in this order, U1 + and U1-, V1- and V1 +, W1 + and W1-, U2- and U2 +, V2 + And V2-, W2- and W2 + are wound in opposite directions and connected in series. The U +, U−, V−, V +, W +, W−, U−, U +, V +, V−, W−, and W + winding arrangements are for the 10-pole 12-slot system.

そして、各組の巻線の巻回方向は、図１に示すように、右巻き→左巻きの順になっており、全ての組で同一となっている。巻線工程は、ステータ鉄心１が、図１に示すように直線状に開いた状態で行われ、巻線工程完了後にステータ鉄心１は円形に成形され、図２に示すようになる。   As shown in FIG. 1, the winding direction of each set of windings is in the order of right winding → left winding, and is the same in all sets. The winding process is performed in a state where the stator core 1 is linearly opened as shown in FIG. 1, and after the winding process is completed, the stator core 1 is formed into a circular shape as shown in FIG.

巻線は、Ｕ１＋、Ｕ１−、Ｖ１−、Ｖ１＋、Ｗ１＋、Ｗ１−を第１群３相巻線４としてΔ結線されており、各相間を結線する結線部１１（Ｕ１＋〜Ｖ１−；Ｕ１−〜Ｗ１＋；Ｖ１＋〜Ｗ１−）からそれぞれ接続端子１３（Ｖ１相）、１２（Ｕ１相）、及び１４（Ｗ１相）が延出され、マイクロコンピュータ６およびＦＥＴ駆動回路７により制御される第１のインバータ９に接続されている。   The windings are Δ-connected with U1 +, U1-, V1-, V1 +, W1 +, W1- as the first group three-phase winding 4, and a connection portion 11 (U1 + to V1-; U1- To W1 +; V1 + to W1-), the connection terminals 13 (V1 phase), 12 (U1 phase), and 14 (W1 phase) are respectively extended and controlled by the microcomputer 6 and the FET drive circuit 7. It is connected to the inverter 9.

同様に、Ｕ２−、Ｕ２＋、Ｖ２＋、Ｖ２−、Ｗ２−、Ｗ２＋の巻線が第２群３相巻線５としてΔ結線されており、各相間の結線部１１（Ｕ２−〜Ｖ２＋；Ｕ２＋〜Ｗ２−；Ｖ２−＋〜Ｗ２＋）からそれぞれ接続端子１６（Ｖ２相）、１５（Ｕ２相）、及び１７（Ｗ２相）が延出され、マイクロコンピュータ６およびＦＥＴ駆動回路８により制御される第２のインバータ１０に接続されている。   Similarly, U2-, U2 +, V2 +, V2-, W2-, W2 + windings are Δ-connected as a second group three-phase winding 5, and a connection portion 11 between each phase (U2- ~ V2 +; U2 + ~ Connection terminals 16 (V2 phase), 15 (U2 phase), and 17 (W2 phase) are respectively extended from W2-; V2-++ to W2 +) and are controlled by the microcomputer 6 and the FET drive circuit 8. The inverter 10 is connected.

各巻線に付した符号はトルクを発生するのに必要な同じ相内での巻線の起磁力の方向を示しており、＋と−では電気角でπ（１８０度）位相が異なる、つまり逆相になっていることを示す。
ここで、図１の結線において、第１群３相巻線４と第２群３相巻線５との間に位相差のない同相の電流を通電したとすると、起磁力が符号通りにならず、トルクが発生しない。 The sign attached to each winding indicates the direction of the magnetomotive force of the winding within the same phase necessary for generating torque, and the phase of π (180 degrees) differs between + and-, that is, the reverse Indicates that it is in phase.
Here, in the connection shown in FIG. 1, if a current of the same phase with no phase difference is passed between the first group three-phase winding 4 and the second group three-phase winding 5, the magnetomotive force is as indicated by the sign. Torque is not generated.

このため、第１群３相巻線４と第２群３相巻線５には、それぞれ、ＦＥＴ駆動回路７及び８、並びに第１及び第２のインバータ９及び１０により、互いにπの位相差を有する電流を通電し、符号通りの起磁力が発生するように巻線されている。各相間の結線部１１は、第１群３相巻線４及び第２群３相巻線５ともに、結線部１１の重なりは最大２つ、すなわち２層で構成されている。   Therefore, the first group three-phase winding 4 and the second group three-phase winding 5 are respectively connected to the phase difference of π by the FET drive circuits 7 and 8 and the first and second inverters 9 and 10. Is wound so that a magnetomotive force is generated as indicated by the sign. In the connection part 11 between the phases, both the first group three-phase winding 4 and the second group three-phase winding 5 have a maximum of two overlapping connection parts 11, that is, two layers.

ステータ鉄心１の内側には、図２に示す如く、外周部に永久磁石１８が配設されたロータ（回転子）１９が設けられており、本実施の形態では１０個の永久磁石が、Ｎ極、Ｓ極交互に配置され、１０極１２スロット方式の永久磁石同期モータを形成している。第１群３相巻線４（Ｕ１＋、Ｕ１−；Ｖ１−、Ｖ１＋；Ｗ１＋、Ｗ１−）と第２群３相巻線５（Ｕ２−、Ｕ２＋；Ｖ２＋、Ｖ２−；Ｗ２−、Ｗ２＋）とは、それぞれ回転軸２０を挟んで、すなわちモータの中心に対して対称に配置されており、各群の各相結線部１１（図示せず）が干渉しないようになっている。   As shown in FIG. 2, a rotor (rotor) 19 having a permanent magnet 18 disposed on the outer peripheral portion is provided inside the stator core 1. In the present embodiment, ten permanent magnets are N A 10-pole, 12-slot permanent magnet synchronous motor is formed by alternately arranging poles and S-poles. First group three-phase winding 4 (U1 +, U1-; V1-, V1 +; W1 +, W1-) and second group three-phase winding 5 (U2-, U2 +; V2 +, V2-; W2-, W2 +) Are arranged symmetrically with respect to the center of the motor, that is, with respect to the center of the motor, so that each phase connection portion 11 (not shown) of each group does not interfere.

この場合、図示のように、回転軸２０を挟んで対向する巻線の配置は、Ｕ１＋とＵ２−、Ｕ１−とＵ２＋、Ｖ１−とＶ２＋、Ｖ１＋とＶ２−、Ｗ１＋とＷ２−、Ｗ１−とＷ２＋となる。
さらに、各群の巻線が分離して配置されていることにより、各群間の相互インダクタンスが小さく、制御性に影響を与えないようになっている。 In this case, as shown in the figure, the winding arrangements facing each other across the rotating shaft 20 are U1 + and U2-, U1- and U2 +, V1- and V2 +, V1 + and V2-, W1 + and W2-, and W1-. W2 +.
Furthermore, since the windings of each group are arranged separately, the mutual inductance between the groups is small, and the controllability is not affected.

ここで、上記の特許文献１について再度考えてみると、この特許文献１では、第１群３相巻線と第２群３相巻線の位相差が電気角でπとなるように巻回方向を逆にしている、つまり、第１群３相巻線を右巻き→左巻きの順で巻線し、第２群３相巻線を左巻き→右巻きの順で巻線し、第１群３相巻線と第２群３相巻線には、位相差のない電流を通電するようにしている。   Here, considering the above Patent Document 1 again, in Patent Document 1, the winding is performed so that the phase difference between the first group three-phase winding and the second group three-phase winding is π in electrical angle. The direction is reversed, that is, the first group three-phase winding is wound in the order of right winding → left winding, the second group three phase winding is wound in the order of left winding → right winding, and the first group A current having no phase difference is applied to the three-phase winding and the second group three-phase winding.

しかしながら、この場合、第１群３相巻線４と第２群の３相巻線５の巻線工程を同時に行うことができなくなり、巻線の工数が増大してしまう。
これに対し本実施の形態によるモータでは、直列接続されているコイルを１組として、直線状のステータ鉄心１に６組のコイルを同時に巻線することができ、巻線工程の工数を減らすことができる。 However, in this case, the winding process of the first group three-phase winding 4 and the second group three-phase winding 5 cannot be performed at the same time, which increases the number of winding steps.
On the other hand, in the motor according to the present embodiment, a set of coils connected in series can be used as a set, and six sets of coils can be wound around the linear stator core 1 at the same time, thereby reducing the number of steps in the winding process. Can do.

このように構成された３相２重化モータにおいては、集中巻ステータの巻線は隣り合う２つのティースを１組として互いに逆方向に連続して巻回され、第１のインバータによって駆動される第１群３相巻線と第２のインバータによって駆動される第２群３相巻線はモータの回転軸に対して対向した位置に配置され、前記第１群３相巻線と前記第２群３相巻線の巻線方向が同一で、第１のインバータの駆動電流と第２のインバータの駆動電流とが、互いにπの位相差を有している構成としたので、巻線の工数が低減し、製造が容易で安価な３相２重化モータが得られるという効果がある。   In the three-phase duplex motor configured as described above, the windings of the concentrated winding stator are wound continuously in opposite directions with two adjacent teeth as one set, and are driven by the first inverter. The second group three-phase winding driven by the first group three-phase winding and the second inverter is disposed at a position facing the rotation shaft of the motor, and the first group three-phase winding and the second group The winding direction of the group three-phase windings is the same, and the driving current of the first inverter and the driving current of the second inverter have a phase difference of π from each other. There is an effect that a three-phase duplex motor that is easy to manufacture and inexpensive can be obtained.

実施の形態２．
本発明の実施の形態２による３相２重化モータを示す図４〜図６において、電磁鋼板を積層して形成されたステータ鉄心１にはティース２が１２個設けられており、上記の実施の形態１と同様に、図示しない樹脂製のインシュレータを介して巻線３が３相を１群として２群巻回され、それぞれの群でΔ結線されている。巻線３は、隣り合う２つのティースを１組として連続して巻回され、直列に接続されている。巻線の巻回方向は、直列に接続された２つのティース間で互いに逆方向になっている。 Embodiment 2. FIG.
4 to 6 showing a three-phase duplex motor according to Embodiment 2 of the present invention, twelve teeth 2 are provided on a stator core 1 formed by laminating electromagnetic steel plates, and the above-described implementation is performed. As in the first embodiment, the winding 3 is wound in two groups with a three-phase group as a group via a resin insulator (not shown), and is Δ-connected in each group. The winding 3 is continuously wound as a set of two adjacent teeth, and is connected in series. The winding directions of the windings are opposite to each other between the two teeth connected in series.

ただし、本実施の形態２の場合には上記の実施の形態１とは異なり、巻線の配置は、図４に示すように、図面の右側から、Ｕ１＋、Ｕ１−、Ｗ１−、Ｗ１＋、Ｖ１＋、Ｖ１−、Ｕ２−、Ｕ２＋、Ｗ２＋、Ｗ２−、Ｖ２−、Ｖ２＋の順になっており、Ｕ１＋とＵ１−、Ｗ１−とＷ１＋、Ｖ１＋とＶ１−、Ｕ２−とＵ２＋、Ｗ２＋とＷ２−、Ｖ２−とＶ２＋が、それぞれ直列接続されている。なお、このＵ＋、Ｕ−、Ｗ−、Ｗ＋、Ｖ＋、Ｖ−、Ｕ−、Ｕ＋、Ｗ＋、Ｗ−、Ｖ−、Ｖ＋の巻線配置は、１４極１２スロット方式用のものである。   However, in the case of the second embodiment, unlike the first embodiment, the winding arrangement is as shown in FIG. 4 from the right side of the drawing, U1 +, U1-, W1-, W1 +, V1 +. , V1-, U2-, U2 +, W2 +, W2-, V2-, V2 + in this order, U1 + and U1-, W1- and W1 +, V1 + and V1-, U2- and U2 +, W2 + and W2-, V2. − And V2 + are respectively connected in series. The U +, U−, W−, W +, V +, V−, U−, U +, W +, W−, V−, and V + winding arrangements are for the 14-pole 12-slot system.

図１との違いは、図６からも分かるように、各相の１組の巻線の符号（＋、−）を入れ替えたものである。
巻線の巻回方向は、右巻き→左巻きの順で、全ての組で同一となっている。巻線工程は、ステータ鉄心１が図４に示すように直線状に開いた状態で行われ、巻線完了後にステータ鉄心１は円形に成形され、図５に示すようになる。 The difference from FIG. 1 is that the signs (+, −) of one set of windings of each phase are exchanged, as can be seen from FIG. 6.
The winding direction of the winding is the same in all sets in the order of right-handed winding → left-handed winding. The winding process is performed in a state where the stator iron core 1 is linearly opened as shown in FIG. 4, and after completion of the winding, the stator iron core 1 is formed into a circular shape as shown in FIG.

巻線は、Ｕ１＋、Ｕ１−、Ｗ１−、Ｗ１＋、Ｖ１＋、Ｖ１−を第１群３相巻線４としてΔ結線されており、各相間を結線する結線部１１（Ｕ１＋〜Ｗ１−；Ｕ１−〜Ｖ１＋；Ｗ１＋〜Ｖ１−）からそれぞれ接続端子１２（Ｕ１相）、１３（Ｖ１相）、及び１４（Ｗ１相）が延出され、マイクロコンピュータ６およびＦＥＴ駆動回路７により制御される第１のインバータ９に接続されている。   The windings are Δ-connected with U1 +, U1-, W1-, W1 +, V1 +, V1- as the first group three-phase winding 4, and a connection part 11 (U1 + to W1-; U1- To V1 +; W1 + to V1-), connecting terminals 12 (U1 phase), 13 (V1 phase), and 14 (W1 phase) are respectively extended and controlled by the microcomputer 6 and the FET drive circuit 7 It is connected to the inverter 9.

同様に、Ｕ２−、Ｕ２＋、Ｗ２＋、Ｗ２−、Ｖ２−、Ｖ２＋の巻線が第２群３相巻線５としてΔ結線されており、各相間の結線部１１（Ｕ２−〜Ｗ２＋；Ｕ２＋〜Ｖ２−；Ｗ２−＋〜Ｖ２＋）からそれぞれ接続端子１５（Ｕ２相）、１６（Ｖ２相）、及び１７（Ｗ２相）が延出され、マイクロコンピュータ６およびＦＥＴ駆動回路８により制御される第２のインバータ１０に接続されている。   Similarly, U2-, U2 +, W2 +, W2-, V2-, V2 + windings are Δ-connected as a second group three-phase winding 5, and a connection portion 11 between each phase (U2- to W2 +; U2 + to Connection terminals 15 (U2 phase), 16 (V2 phase), and 17 (W2 phase) are respectively extended from V2-; W2-++ to V2 +) and controlled by the microcomputer 6 and the FET drive circuit 8. The inverter 10 is connected.

各巻線の符号は同じ相内での巻線の起磁力の方向を示しており、＋と−では電気角でπだけ位相が異なる、つまり逆相になっていることを示す。ここで図４の結線において、第１群３相巻線４と第２群３相巻線５に位相差の無い同相の電流を通電すると、上述の如く、符号通りの起磁力が発生しないことが分かる。   The sign of each winding indicates the direction of the magnetomotive force of the winding within the same phase, and + and − indicate that the electrical angle is different in phase by π, that is, is opposite in phase. Here, in the connection shown in FIG. 4, when a current of the same phase having no phase difference is applied to the first group three-phase winding 4 and the second group three-phase winding 5, no magnetomotive force is generated as described above. I understand.

このため、第１群３相巻線４と第２群３相巻線５には、互いにπの位相差を有する電流を通電し、符号通りの起磁力が発生するように、マイクロコンピュータ６がＦＥＴ駆動回路７及び８を介してそれぞれ第１及び第２のインバータ９及び１０を制御するように構成されている。各相間の結線部１１は、第１群３相巻線４及び第２群３相巻線５ともに、結線部１１の重なりは最大２つ、すなわち２層で構成されている。   For this reason, the microcomputer 6 is connected to the first group three-phase winding 4 and the second group three-phase winding 5 so that currents having a phase difference of .pi. The first and second inverters 9 and 10 are controlled via the FET drive circuits 7 and 8, respectively. In the connection part 11 between the phases, both the first group three-phase winding 4 and the second group three-phase winding 5 have a maximum of two overlapping connection parts 11, that is, two layers.

ステータ鉄心１の内側には外周部に永久磁石１８が配されたロータ１９が設けられており、本実施の形態では、１４個の永久磁石１８が、Ｎ極、Ｓ極交互に配置され、１４極１２スロット方式の永久磁石同期モータを形成している。第１群３相巻線Ｕ１＋、Ｕ１−、Ｗ１−、Ｗ１＋、Ｖ１＋、Ｖ１−と、第２群３相巻線Ｕ２−、Ｕ２＋、Ｗ２＋、Ｗ２−、Ｖ２−、Ｖ２＋とは、それぞれ回転軸２０を挟んで、すなわちモータの中心に対して対称に配置されており、各群の各相結線部が干渉しないようになっている。   A rotor 19 having permanent magnets 18 arranged on the outer peripheral portion is provided inside the stator core 1. In the present embodiment, 14 permanent magnets 18 are alternately arranged in N and S poles. A pole 12 slot type permanent magnet synchronous motor is formed. The first group three-phase windings U1 +, U1-, W1-, W1 +, V1 +, V1- and the second group three-phase windings U2-, U2 +, W2 +, W2-, V2-, V2 + are respectively rotating shafts. 20 are arranged symmetrically with respect to the center of the motor, so that each phase connection portion of each group does not interfere.

この場合も、上記の実施の形態１と同様に、回転軸２０を挟んで対向する巻線の配置は、Ｕ１＋とＵ２−、Ｕ１−とＵ２＋、Ｖ１−とＶ２＋、Ｖ１＋とＶ２−、Ｗ１＋とＷ２−、Ｗ１−とＷ２＋となる。
さらに、各群の巻線が分離して配置されていることにより、各群間の相互インダクタンスが小さく、制御性に影響を与えないようになっている。 Also in this case, as in the first embodiment, the winding arrangements facing each other across the rotating shaft 20 are U1 + and U2-, U1- and U2 +, V1- and V2 +, V1 + and V2-, and W1 +. W2-, W1- and W2 +.
Furthermore, since the windings of each group are arranged separately, the mutual inductance between the groups is small, and the controllability is not affected.

このように構成された３相２重化モータにおいては、集中巻ステータの巻線は隣り合う２つのティースを１組として互いに逆方向に連続して巻回され、第１のインバータによって駆動される第１群３相巻線と第２のインバータによって駆動される第２群３相巻線はモータの回転軸に対して対向した位置に配置され、第１群３相巻線と第２群３相巻線の巻線方向は同一で、第１のインバータの駆動電流と第２のインバータの駆動電流とは、互いにπの位相差を有しているので、巻線の工数が低減し、製造が容易で安価な３相２重化モータが得られるという効果がある。   In the three-phase duplex motor configured as described above, the windings of the concentrated winding stator are wound continuously in opposite directions with two adjacent teeth as one set, and are driven by the first inverter. The first group three-phase winding and the second group three-phase winding driven by the second inverter are arranged at positions facing the rotation shaft of the motor, and the first group three-phase winding and the second group 3 The winding direction of the phase winding is the same, and the driving current of the first inverter and the driving current of the second inverter have a phase difference of π, so the number of winding steps is reduced and the manufacturing This is advantageous in that an inexpensive and inexpensive three-phase duplex motor can be obtained.
