Description

  The present invention relates to an armature for a rotating electrical machine and a method for manufacturing the same.

In order to reduce the size and increase the output of a motor as a rotating electric machine, it is effective to improve the winding space factor and increase the number of poles in the armature. On the other hand, for example, in a motor having a large number of slots, the winding is generally wound by a lap winding method, and the winding feed pitch in winding processing is generally one slot (for example, Patent Document 1).
JP 2000-6050 A

  By the way, when the winding feed pitch in the lap winding method is 1 slot, the lower layer coil (winding portion) wound around one teeth group is replaced by the upper layer coil wound around another teeth group. In order to close the end face of the slot to be accommodated, the fit of the coil into the slot (coil overlap) is deteriorated, the dead space is increased, and the space factor is inevitably reduced.

  In addition, since it is necessary to connect the coil so that it covers all segments of the commutator, the number of connections to the commutator increases with the increase in the number of poles of the motor, the number of crossover wires increases, and the fit also deteriorates. . In particular, when adopting the short α connection method, the dead space becomes larger and the space factor is reduced as the connecting wire is separated from the rotation axis, while when using the long α connection method, As the wire is wound around the rotating shaft, the connecting wire becomes longer. Furthermore, the winding processing time is increased by the amount of the connection operation to the commutator, and as a result, the production cost must be increased. Furthermore, the number of brushes increases.

  In addition, the "internally connected commutator" that has a circuit that short-circuits between specific segments of the commutator inside the commutator, and the "short-circuited winding" that short-circuits specific segments of the commutator by windings are known. Yes. The purpose of these “internally connected commutator” and “short-circuited winding” is to energize each slidable segment of a pair of brushes of the same polarity and the coil connected to that segment among multiple brushes in a multi-pole motor. The timing is synchronized to prevent such a slight shift in energization timing. This synchronization of energization timing improves brush life reduction due to commutation variation, improves rotation unevenness due to excitation deviation, reduces the number of brushes in a multipolar motor, or uses concentrated winding distributed excitation. It has been proposed to use it.

However, these conventional configurations have not been studied at all for the reduction of the winding space factor and the reduction of the number of connections to the commutator in the winding process.

The core 112 has 24 teeth 112a having a substantially T shape that are arranged at equiangular intervals and extend radially, and a slot 112b is formed in a space between adjacent teeth 112a.

  Furthermore, the armature 103 has a cylindrical commutator 113 fixed to the rotating shaft 111 in a manner aligned with the core 112 in the axial direction. As shown in FIG. 3, the commutator 113 includes a commutator body 141 and a short-circuit member 151. The main body insulating material 142 constituting the commutator main body 141 has a substantially cylindrical shape, and 24 segments 1 to 24 having a substantially rectangular plate shape are arranged at equal angular intervals on the outer peripheral surface thereof. A peripheral wall portion 144 that protrudes in the axial direction along the inner peripheral surface is formed on the end surface on the one side in the axial direction of the main body insulating material 142 (the lower side surface in FIG. 3 and the end surface on the core 112 side). ing. The main body insulating material 142 is formed with an annular short-circuit member accommodating recess 145 that continues from the peripheral wall portion 144 to the outer peripheral surface.

  The segments 1 to 24 have a length equivalent to the axial length of the outer peripheral surface of the main body insulating material 142, and are fixed to the outer peripheral surface of the main body insulating material 142 so as to form a substantially cylindrical shape as a whole. Yes. Each segment 1-24 is arrange | positioned so that the end surface of the axial direction one side may become flush with the bottom face of the said short circuit member accommodating recessed part 145. FIG. These segments 1 to 24 are brought into sliding contact (pressing contact) with the anode and cathode side power supply brushes 107 and 108 from the outside in the radial direction (see FIG. 2). The eight segments 2, 5, 8, 11, 14, 17, 20, and 23 of all the segments 1 to 24 protrude radially outward at the end on one axial side (core 112 side). A connection claw 30 is formed (see FIG. 1). That is, every two segments having the connecting claws 30 are arranged at equal angular intervals.

  As shown in FIG. 4, the short-circuit member 151 is interposed between two short-circuit component groups 31a and 31b having basically the same shape except that they are symmetrical, and both short-circuit component groups 31a and 31b. And an insulating material 32. Each short circuit component group 31a, 31b includes a plurality of outer peripheral terminals 33a, 33b arranged in the circumferential direction, a plurality of inner peripheral terminals 34a, 34b arranged in the circumferential direction inside the outer terminals 33a, 33b, A plurality of connecting portions 35a and 35b for connecting the outer peripheral side terminals 33a and 33b and the inner peripheral side terminals 34a and 34b with a predetermined angle shift in the circumferential direction are formed in the same plane. In the present embodiment, 24 outer peripheral terminals 33a and 33b, inner peripheral terminals 34a and 34b, and connecting portions 35a and 35b are formed for each of the short circuit component groups 31a and 31b. The outer peripheral side terminals 33a and 33b, the inner peripheral side terminals 34a and 34b, and the connecting portions 35a and 35b constitute a conductive plate.

  Each outer peripheral side terminal 33a, 33b has an outer diameter equivalent to the outer diameter of the segments 1-24 and a circumferential width smaller than the segments 1-24, and the segments 1-24 and the outer peripheral side terminals 33a , 33b (short-circuit component group 31a, 31b) are joined together by spot welding, for example, in a state of being overlapped in the axial direction. In other words, the segments 1 to 24 and the short circuit component groups 31a and 31b are electrically connected by joining the outer peripheral terminals 33a and 33b together with the segments 1 to 24.

  On the other hand, each inner peripheral side terminal 34 a, 34 b has an inner diameter equivalent to the outer diameter of the peripheral wall portion 144. These inner peripheral side terminals 34a and 34b are joined together by spot welding, for example, in a state where they are overlapped in the axial direction. That is, the short circuit component groups 31a and 31b are electrically connected by joining the inner peripheral terminals 34a and 34b.

  Each of the connecting portions 35a and 35b connects the outer peripheral side terminals 33a and 33b and the inner peripheral side terminals 34a and 34b with a predetermined angle (60 degrees) shifted in the circumferential direction (with four terminals shifted). As a result, the outer peripheral terminals 33a and 33b that are shifted by a predetermined angle (120 degrees) in the circumferential direction (shifted by four terminals) are connected. Each connecting portion 35a, 35b is formed along an involute curve. These connecting portions 35a and 35b are overlapped (stacked) in the same direction so as to be shifted in opposite directions as viewed from the axial direction.

  The insulating material 32 is made of an insulating resin material, and is formed in an annular shape having an inner diameter and an outer diameter equivalent to the distance in the radial direction to the base end portion and the distal end portion of the connecting portions 35a and 35b. The insulating material 32 integrally connects the short-circuit constituting member groups 31a and 31b with the connecting portions 35a and 35b being in non-contact with each other. That is, the short circuit component groups 31 a and 31 b are overlapped (stacked) in the axial direction so that the connecting portions 35 a and 35 b are not in contact with each other via the insulating material 32. The short-circuit constituting member groups 31a and 31b having a structure divided into a plurality in the circumferential direction are integrated by interposing the insulating material 32 and are insulated from each other at the connecting portions 35a and 35b.

  The short-circuit member 151 having such a structure is accommodated in the short-circuit member accommodating recess 145 in such a manner that the inner peripheral terminals 34a and 34b are inserted in the axial direction into the peripheral wall portion 144 of the commutator body 141. The thickness of the short-circuit member 151 is set so as not to protrude in the axial direction from the peripheral wall portion 144 in the accommodated state in the short-circuit member accommodating recess 145. The short-circuit member 151 (short-circuit component group 31a, 31b) is electrically connected to the segments 1 to 24 and is fixed to the commutator body 141. Needless to say, eight of the outer peripheral terminals 33 a are connected to the segments 2, 5, 8, 11, 14, 17, 20, 23 having the connection claws 30. Accordingly, the segments 2, 5, 8, 11, 14, 17, 20, and 23 having the connection claws 30 are shifted by a predetermined angle (120 degrees) in the circumferential direction via the short-circuit member 151 (eight segments are divided). It is short-circuited so that it has the same potential as the other two segments. For example, the segment 8 is short-circuited to the two segments 16 and 24 without the connection claw 30 via the short-circuit member 151.

  As shown in FIG. 1, the core 112 has a plurality of (eight) main winding portions 114 (in FIG. 1, the main winding portion 114 of the first layer that is the start of winding is shown schematically). ) Is wound, and a commutator 113 is electrically connected to the main winding portion 114.

  Here, the main winding portion 114 and the like will be further described with reference to FIG. 5A is a schematic diagram showing the positional relationship between the teeth 112a and the slots 112b of the core 112 and the segments 1 to 24 of the commutator 113 in the armature 103, and FIG. It is explanatory drawing which expands and shows 103 to planar shape. In the present embodiment, the radial straight line passing between the adjacent segments 1 to 24 coincides with the circumferential center line of the tooth 112a, and each segment 1 to 24 is disposed to face the slot 112b in the radial direction. ing. In FIG. 5, slot numbers “1” to “24” are assigned to the slots 112b arranged to face the segments 1 to 24, respectively.

  As shown in FIG. 5, the main winding portion 114 includes three winding portions 41, 42, and 43, each of which is wound a predetermined number of times on three tooth groups including four adjacent teeth 112 a, and two of them. The connecting wires 44 and 45 extending from the winding portions 41 and 43 and connected to two predetermined segments having the connecting claws 30, and between the winding portions 41 and 42 and between the winding portions 42 and 43 are connected. Intermediate crossover lines 46 and 47 are continuously provided. The connecting wire 44 connected to one segment is connected to the winding portion 41 that is stored in the slot 112b having a number obtained by subtracting “2” from the number corresponding to the code of the segment, and connected to the other segment. The connected crossover wire 45 is connected to a winding part 43 that is accommodated in a slot 112b having a number obtained by adding “1” to a number corresponding to the code of the segment. In addition, the winding portions 41 to 43 are arranged so as to straddle the four teeth 112a between the adjacent winding portions 41 to 43, and the respective portions are connected by intermediate crossover wires 46 and 47. Yes.

  Specifically, for example, in the main winding portion 114 starting from the segment 8 having the connection claws 30, the other end of the crossover wire 44 having one end connected to the segment 8 is guided to the slot 112 b having the number “6”. The winding portion 41 that is continuous with the connecting wire 44 is wound a predetermined number of times in a normal winding around the teeth group between the winding portions 41 in a manner of being accommodated in the slots 112b of the numbers “6” and “2”. Yes. The intermediate connecting wire 46 having one end connected to the winding portion 41 from the slot 112 b with the number “2” is led to the slot 112 b having the other end with the number “14” and is connected to the intermediate connecting wire 46. The winding portion 42 is wound a predetermined number of times in a normal winding around the teeth group between the winding portions 42 in such a manner that the winding portion 42 is housed in the slots 112b of the numbers “14” and “10”. Further, the intermediate connecting wire 47 having one end continuous with the winding portion 42 from the slot 112 b with the number “10” is led to the slot 112 b with the other end at the number “22”, and is continuous with the intermediate connecting wire 47. The winding portion 43 is wound a predetermined number of times in a normal winding around a group of teeth between the slots 112b having the numbers “22” and “18”. The other end of the connecting wire 45 having one end connected to the winding portion 43 from the slot 112 b of the number “18” is connected to the segment 17. That is, the main winding portion 114 has a triple coil structure in which three winding portions 41 to 43 that are overlapped are connected.

  The intermediate crossover wires 46 and 47 are to be connected between the winding portions 41 and 42 and between the winding portions 42 and 43 when the corresponding winding portions 41 to 43 are individually connected to segments. Connected to the segment without connecting. In other words, the energization to the winding portions 41 to 43 that are not connected to the segment is caused by the slidable segment of the anode-side power supply brush 107 or the cathode-side power supply brush 108 that is short-circuited via the short-circuit member 151 and the crossover. This is done via connected segments of lines 44 and 45. Specifically, for example, one of the anode-side power supply brush 107 and the cathode-side power supply brush 108 is slidably contacted with any one of the segments 8, 16, and 24 that are short-circuited via the short-circuit member 151. The other of the anode-side power supply brush 107 and the cathode-side power supply brush 108 is brought into sliding contact with any one of the segments 1, 9, 17 short-circuited via the crossover wires 44, 45 and the intermediate crossover wires 46, All winding portions 41 to 43 are energized through 47.

The main winding portion 114 starting from the other segments 2, 5, 11, 14, 17, 20, 23 having the connection claws 30 also has a similar structure.
In the motor 101 having such a structure, when power is supplied from the outside to the anode-side power supply brush 107 and the cathode-side power supply brush 108, the main winding portion 114 (winding) of the armature 103 is connected via the commutator 113. The line portions 41 to 43) are energized, and the armature 103 (rotating shaft 111) rotates.

  Next, a method for manufacturing the armature 103 will be described. The armature 103 is manufactured by sequentially performing a winding process and a connecting process after the core 112 and the commutator 113 are mounted on the rotating shaft 111.

  Here, the winding of the main winding portion 114 around the core 112 in the winding step is performed by a known winding winding device 50 as shown in FIG. That is, the winding winding device 50 spans the winding 51 by supplying the winding 51 while rotating the core 112 or the like mounted on the rotating shaft 111. In addition, the winding winding device 50 winds the winding 51 around a predetermined group of teeth 112 a by supplying the winding 51 while rotating the flyer 52. That is, the side former 53 of the winding device 50 is arranged around the core 112 and covers a predetermined portion thereof, so that the winding 51 is guided in a gap formed by being covered with the side former 53. Thus, the winding 51 is wound. By using the winding winding device 50 having such a structure, the winding 51 is wound around a predetermined group of teeth and is connected to the commutator 113 at the connection claw 30 to be connected to the main winding portion 114. Is formed.

  Specifically, as shown by a solid line in FIG. 5 (b), the winding winding device 50 connects the winding to the segment 8 having the connection claw 30 to start the segment 8 (winding start), A winding wire is extended from the segment 8 to the slot 112b of the number “6” to form the crossover wire 44. Further, the winding winding device 50 continuously winds the winding a predetermined number of times around the group of teeth between the slots 112b of the numbers “6” and “2” in succession to the connecting wire 44, and the winding portion 41 is formed. Further, the winding winding device 50 extends the winding from the slot 112 b with the number “2” to the slot 112 b with the number “14” continuously with the winding portion 41 to form the intermediate crossover wire 46. Further, the winding winding device 50 continuously winds the winding a predetermined number of times around the teeth group between the slots 112b of the numbers “14” and “10” continuously with the intermediate crossover wire 46, and the winding Part 42 is formed. Further, the winding winding device 50 extends the winding from the slot 112 b with the number “10” to the slot 112 b with the number “22” continuously with the winding part 42, thereby forming the intermediate crossover wire 47. Further, the winding winding device 50 continues the intermediate jumper wire 47, winds the winding a predetermined number of times around the teeth group between the slots 112b of the numbers “22” and “18”, and winds the winding. A line portion 43 is formed. The winding winding device 50 extends the winding from the finally formed winding portion 43 to the segment 17 having the connection claw 30 to form the crossover wire 45 and connects the winding to the segment 17. To do. As described above, the winding device 50 forms the main winding portion 114 as the first layer.

  Subsequently, as shown by a broken line in FIG. 5 (b), the winding winding device 50 starts from the segment 17 to which the winding is connected in the above-described manner, and the main winding portion 114 as the first layer In the same manner, the main winding portion 114 as the second layer is formed. As is apparent from the figure, the slot number of the slot 112b in which the second-layer winding portions 41 to 43 are accommodated is the slot number of the slot 112b in which the first-layer winding portions 41 to 43 are accommodated. One by one. That is, the lap winding in this embodiment is a so-called lead angle lap.

  Thereafter, the main winding part 114 is sequentially formed by the winding winding device 50 until the eighth layer is reached, whereby the winding process is completed. Therefore, the winding process of this embodiment is a so-called single winding using one winding winding device 50.

  When the winding process is completed, the windings (crossover wires 44, 45) connected to the segments 2, 5, 8, 11, 14, 17, 20, 23 are joined by fusing or the like in the subsequent connection process. The Thereby, the commutator 113 and the main winding portion 114 are electrically connected, and the manufacture of the armature 103 is completed.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the winding portions 41 and 42 and the winding portions 42 and 43 are connected to the segments to be connected when the winding portions 41 to 43 are individually connected to the segments. Without being connected, they are directly connected via the intermediate crossover lines 46 and 47. The segments to which the winding portions 41 to 43 are to be connected are connected to the same potential as the predetermined segments to which the connecting wires 44 and 45 are connected by the short-circuit member 151. That is, the winding portions 41 to 43 are supplied with power through the short-circuit member 151 and the crossover wires 44 and 45. Accordingly, the number of connecting wires can be reduced and the number of connecting wires can be reduced and the connecting portion can be processed in a compact manner because the connection to the segments of the winding portions 41 to 43 can be partially omitted. Can be improved. Specifically, the 48 crossover lines that are originally required in the case of 24 slots can be completed with a total of 16 crossover lines 44 and 45, which are two in each main winding portion 114.

  Further, in the winding process (winding step), the number of connections to the commutator 113 (segments 1 to 24) can be reduced by the amount that the connection to the segments of the winding portions 41 to 43 can be omitted.
