Description

  The present invention relates to a stator of a rotating electrical machine, particularly a 10-pole 12-slot rotating electrical machine, a method for manufacturing the stator, and a winding device for the stator.

  Many stator cores of rotating electrical machines are manufactured by stamping and laminating thin plates with a press. The stator cores are divided into separate core structures, and coils are wound around each of the split cores. Are integrated by caulking or welding to form a stator, so that the density of the coil can be increased and the productivity of the winding process can be improved.

  In addition, a technique has been proposed in which the number of parts such as terminals and connection work are reduced by continuously winding the divided iron core without cutting the crossover. For example, when configuring a stator of a rotating electric machine, an iron core divided in units of one tooth is wound around each tooth in a state of being arranged in a ring shape larger than the outer diameter of the armature and spaced apart in the circumferential direction. In addition, a method for manufacturing an armature has been proposed in which a connecting wire guide portion is provided on one end side in the axial direction of the insulating bobbin, and the connecting wire is disposed on the upper portion of the coil, thereby preventing contact between the connecting wire and the coil (for example, Patent Document 1).

  The divided laminated iron cores 1a and 1b include laminated back yoke portions 11a and 11b and laminated tooth portions 12a and 12b protruding inward from the laminated back yoke portions 11a and 11b, respectively. The pitch interval between the two divided laminated cores 1a and 1b is P. The divided laminated iron cores 1a and 1b are thinly connected so that the end portions 11at and 11bt in the circumferential direction of the laminated back yoke portions 11a and 11b can be bent with the axis Q shown in FIG.

  Here, in order to make the structure foldable, the connecting portions 11 of the laminated back yoke portions 11a and 11b are thin-walled. However, the present invention is not limited to this, and for example, lamination using caulking unevenness provided in the laminating direction is used. The back yoke portions 11a and 11b may be configured to be rotatable as hinges.

  Dovetail grooves 11a1 and 11b1 for attaching the divided laminated iron cores 1a and 1b to a chuck mechanism, which will be described later, are provided at the center portions on the outer peripheral side of the laminated back yoke portions 11a and 11b. The dovetail grooves 11a1 and 11b1 extend in the axial direction from the upper end portion to the lower end portion of the laminated back yoke portions 11a and 11b.

  FIG. 6 is a view showing a state where the insulating bobbins 3a (first insulating bobbins) and 3b (second insulating bobbins) are mounted on the divided laminated cores 1a and 1b of the pair of divided laminated cores 1 shown in FIG. For convenience of the following description, FIG. 6 is drawn with the top and bottom reversed compared to the state of FIG. As shown in FIG. 6, the divided laminated iron cores 1a and 1b are equipped with an insulating bobbin 3a and an insulating bobbin 3b which are divided into two perpendicular to the axial direction.

  For example, in the case of the U phase, a pair of divided laminated iron cores 1 (divided laminated iron cores 1a and 1b) are used as two sets of one set of U-phase winding part groups 1U by a winding process described later. A coil 8 is continuously wound around 1a and 1b to form a U-phase divided stator group 10U for one phase.

The stators 100 of the 10-pole 12-tooth three-phase DC brushless motor are configured by integrating the parts by welding or adhesion.

Next, the configuration of the insulating bobbins 3a and 3b will be described with reference to FIGS.
7A to 7C are perspective views of the insulating bobbin 3a viewed from three different directions.
FIGS. 8A to 8C are perspective views of the insulating bobbin 3b viewed from three different directions.
An insulating bobbin 3a and an insulating bobbin 3b are mounted on the divided laminated iron cores 1a and 1b from above and below in order to ensure insulation between the divided cores 1a and 1b.

  The insulating bobbin 3a is similar in shape to the coil insulating portion 36a having a shape covering the laminated tooth portions 12a and 12b and the inner peripheral surface of the laminated tooth portions 12a and 12b extending in the axial direction as it is, and the upper end surface 35au is in the axial direction. It consists of an inner wall 35a that is vertical and an outer wall 34a (first outer wall) that stands up in the axial direction from the inner peripheral edge of the laminated back yoke portions 11a and 11b.

  Inner end wire guides 35a1 and 35a2 rising in the axial direction from the upper end surface 35au are provided at both circumferential ends of the upper end surface 35au of the inner wall 35a of the insulating bobbin 3a. The inner end wire guides 35a1 and 35a2 have a hook shape protruding to the inner peripheral side. Between the two inner end wire guides 35a1 and 35a2, an inner central wire guide 35a3 that rises in the axial direction to approximately the same height as the inner end wire guides 35a1 and 35a2 and extends in the circumferential direction is provided. And, between the inner end wire guide 35a1 and the inner central wire guide 35a3, and between the inner end wire guide 35a2 and the inner central wire guide 35a3, wire paths Ma1 and Ma2 that pass through the upper end surface 35au in the radial direction are formed. Is done.

  The bottom surfaces of the wire paths Ma1 and Ma2, that is, the positions of the upper end surfaces 35au are located on the inner wall side when the coil 8 is wound around the divided laminated cores 1a and 1b via the insulating bobbins 3a and 3b as shown in FIG. The position is higher than the end position. Of the connecting wires between the coils 8 and 8, the separating connecting wire 41 that connects the coils 8 that are not adjacent to each other passes through the bottom surfaces of the wire paths Ma1 and Ma2, and the roots of the inner end wire guides 35a1, 35a2, and 35a3. Along the upper end surface 35au.

  On the other hand, as shown in FIG. 7, the outer wall 34a of the insulating bobbin 3a extends in the axial direction from a position that is substantially the same as or lower than the height of the axial end of the coil insulating portion 36a, and comes out in the radial direction. Slit-like wire paths Ma3 and Ma4 are provided. In addition, on the outer wall 34a of the insulating bobbin 3a, three spaced-apart-line support protrusions 31a1 to 31a3 are provided for preventing contact between the spaced-across lines 41. Among them, the separation crossover support protrusions 31a1 and 31a3 provided at both ends in the circumferential direction are hook-like separation crossover support protrusions that are open in the axial direction. The separation connecting wire support protrusions 31a1 and 31a3 serve as products to prevent the separation connecting wires 41 of other phases from coming into contact with each other. It also plays the role of Further, the separation connecting wire 41 is prevented from separating radially outward from the outer peripheral surface of the stator 100. The spacing crossover support protrusions 31 a 1 and 31 a 3 are not limited to the hook shape, but can be hooked to the spacing crossover 41 in the axial direction, and can be regulated out of the plane so that the spacing crossover 41 does not leave the outer peripheral surface of the stator 100. I just need it. Furthermore, a stage portion 37a extending in the circumferential direction is provided at the root of the outer wall 34a, that is, outside the bottom of the wire paths Ma3 and Ma4 so as to cover the outer peripheral edge of the laminated back yoke portions 11a and 11b. The contact between the divided laminated iron cores 1a and 1b and the separation connecting wire 41U can be avoided by drawing the separation connecting wire 41U along the upper surface of the stage portion 37a (first stage portion).

  The insulating bobbin 3b includes a coil insulating portion 36b having a shape covering the laminated tooth portions 12a and 12b, an inner wall 35b similar to a shape obtained by extending the inner peripheral surfaces of the laminated tooth portions 12a and 12b in the axial direction, and a laminated back yoke portion. It is comprised from the outer wall 34b (2nd outer wall) standing in the axial direction from 11a, 11b. The major difference between the insulating bobbin 3a and the insulating bobbin 3b is that the insulating bobbin 3a has an upper end surface 35au and includes inner end wire guides 35a1 and 35a2 and an inner central wire guide 35a3, whereas the insulating bobbin 3b. The upper end in the axial direction has a narrow radial width and does not include a wire guide.

  Further, the outer peripheral surface of the outer wall 34b of the insulating bobbin 3b is not provided with projections such as the separation jumper support projections 31a1 to 31a3 of the insulating bobbin 3a. The outer wall 34b of the insulating bobbin 3b is provided with slit-like wire paths Mb3 and Mb4 in the radial direction, and the bottom surfaces of the wire paths Mb3 and Mb4 are equal to or lower than the upper end surface of the coil insulating portion 36b. ing. Similar to the insulating bobbin 3a, this is intended to prevent the first turn coil 8 from interfering with the coil 8 wound later.

  Further, at the lower end of the outer wall 34b of the insulating bobbin 3b, similarly to the insulating bobbin 3a, a stage portion 37b (second stage portion) extending in the circumferential direction so as to cover the outer peripheral edge of the laminated back yoke portions 11a and 11b. ) Is provided, and contact between the adjacent crossover wire 43 and the divided laminated cores 1a and 1b can be avoided.

FIG. 11 is a perspective view showing a state immediately after the winding of the one-phase divided stator group 10X. Since the difference between the U, V, and W phase divided stator groups in the state where the winding is finished is the length of the separation jumper wire and the winding direction of each coil 8, FIG. 9 to FIG. It is a common drawing of a phase.

  As described above, after the U-phase split stator group 10U, the V-phase split stator group 10V, and the W-phase split stator group 10W are integrated, the separation crossover 41U of the U-phase split stator group 10U is Between the stage portion 37a provided on the outer wall 34a of the insulating bobbin 3a and the separation wire support protrusions 31a1 to 31a3 (the stage portion 37a). Place it on top). Next, the separation wire 41V of the V-phase divided stator group 10V is wound around the laminated back yoke portions 11a and 11b of the other-phase divided stator group sandwiched therebetween, and provided on the outer wall 34a of the insulating bobbin 3a. It arrange | positions on the separation crossover support protrusion 31a1-31a3.

  Finally, the separation connecting wire 41W of the W-phase split stator group 10W is wound around the inner periphery of the stator 100.

It passes along the inner end wire guides 35a1 and 35a2 and the inner center wire guide 35a3 on the upper end surface 35au from the teeth U3 to the teeth V4 through the path Ma1. Thereafter, the wire passes from the wire path Ma2 of the tooth V4 to the inner peripheral side of the stator 100, and is connected from the wire path Ma1 of the adjacent tooth W3 to the coil 8b.

  In the above description, the separation connecting wire 41W passes over the upper end surface 35au from the teeth U3 to the teeth V4. However, the separation connecting wire 41W is arranged on the inner peripheral side from the coil side end surface of the inner wall 35a of the insulating bobbin 3a.

As long as it is not in contact with the other spaced-apart connecting wires 41U and 41V.

  In the present embodiment, the arrangement of the separation jumpers 41U to 41W has been described so as to correspond to FIG. 3, but the invention is realized even if the U phase, the V phase, and the W phase are switched for convenience of control of the rotating electrical machine. Needless to say. Further, with respect to the connecting wire that turns the laminated back yoke portions 11a and 11b, the separating connecting wire 41U that is the lower side of the separating connecting wire support protrusions 31a1 to 31a3 in the above description is located above the separating connecting wire support protrusions 31a1 to 31a3.

  The index table 53 includes a chuck mechanism 51a provided with a drive mechanism 52a and a chuck mechanism 51b provided with a drive mechanism 52b, in parallel with the rotational drive shaft C1 of the drive mechanism 52a and the rotational drive shaft C2 of the drive mechanism 52b, respectively. The table is mounted so as to be rotatable around a rotation axis T existing between the rotation drive axis C1 and the rotation drive axis C2. The clamp mechanism 54 clamps the winding start wires 40U to 40W of the coil 8 with power such as fluid pressure. The clamp mechanism 54 is provided so as to exist above the rotation drive shafts C1 and C2 and on an extension line when the coil 8 is wound.

  Further, the winding device 50 is opposed to the respective winding portions UK1 to UK4 in order from the outer peripheral side, and while supplying the conducting wire 6, the winding portions UK1 to UK4 around the axis R (the central axis of the winding portion). Is provided with a flyer mechanism 58 that winds the coil 8 around each of the winding portions UK1 to UK4.

  The flyer mechanism 58 slides in the direction of the arrow X in FIG. 12 in synchronism with the turning motion for the purpose of improving the alignment of the coils 8. The two chuck mechanisms 51a and 51b are arranged at point-symmetrical positions around the rotation axis T. In the chuck mechanism on the side where the flyer mechanism 58 is not opposed (chuck mechanism 51a in FIG. 12), The winding group can be attached and detached. As a result, it is possible to simultaneously load a work during the winding of the coil, and the productivity of the stator 100 can be improved.

  The chuck mechanisms 51a and 51b have a claw mechanism 520 including four sets of fixed claws 521 and movable claws 522 that can be opened and closed around the rotation drive shafts C1 and C2, and the movable claws 522 are opposite to the fixed claws 521. The fixed claw 521 and the movable claw 522 are engaged with the dovetail grooves 11a1 and 11b1 provided on the outer peripheral surfaces of the divided laminated cores 1a and 1b. Further, the four movable claws 522 are all integrated, and the four movable claws 522 are set to open and close by the same amount at the same time. Further, a binding pin 56 is provided on the upper end surfaces of the chuck mechanisms 51a and 51b.

  As shown in FIG. 13, the chuck mechanisms 51 a and 51 b include a straight line B1 that connects the axes of the laminated tooth portions 12 a of the two divided laminated iron cores 1 a and the axis of the laminated tooth portions 12 b of the two divided laminated iron cores 1 b. The winding portions UK1 to UK4 are positioned so that all of the straight lines B2 connecting the hearts pass through the rotation drive shafts C1 and C2. Thereby, each winding part UK1-UK4 can be moved to the same position with respect to the flyer mechanism 58 only by rotating the rotational drive shaft C1, C2, and the adjustment time of the winding operation of the winding device 50 can be shortened. It has a configuration.

  Further, the chuck mechanisms 51a and 51b are arranged so that the separation connecting wires 41U to 41W are arranged between the second winding portion (UK2 in the drawing) and the third winding portion (UK3 in the drawing) as the winding order of the coil 8. An adjustment hook 55 used for hooking is provided. The adjustment hook 55 extends stepwise in the axial direction, and has three grooves 55U, 55V, and 55W for each phase of UVW. Since the lengths of the separation connecting wires 41U to 41W differ depending on the routing route, the grooves 55U to 55W of the adjustment hooks 55 for each phase are used to adjust the respective lengths. If the allowable value of the length of the separation wire 41 is relatively wide, for example, the U-phase groove 55U and the V-phase groove 55V that are wound around the outer periphery of the stator 100 are shared. It is good also as two grooves. Furthermore, by providing the adjustment hook 55 with a function of moving in the axial direction, a plurality of types of stators can be handled.

Next, the winding process of winding the coil 8 around the U-phase winding part group (set of UK1 to UK4) for the U-phase will be described.
As shown in FIG. 14, the winding portions UK1 to UK4 in which the insulating bobbins 3a and 3b are assembled are attached to the chuck mechanism 51a of the winding device 50 (assuming the use starts from the chuck mechanism 51a). It is thrown so that the other side becomes the upper side. When the movable claw 522 provided in the chuck mechanism 51a is opened to the opposite side to the fixed claw 521, all the dovetail grooves 11a1 and 11b1 are simultaneously grasped and fixed to the chuck mechanism 51a.

  Next, the winding part UK1 around which the coil 8a is wound first is made to face the axis R of the flyer mechanism 58. The conducting wire 6 is supplied from the nozzle 58 a of the flyer mechanism 58, and the terminal portion of the conducting wire 6 is clamped by the clamping mechanism 54 as the winding start wire 40. Next, after passing the winding start wire 40U through the wire path Mb3 of the insulating bobbin 3b of the winding portion UK1 facing the flyer mechanism 58, the coil 8a is wound by the turning operation of the flyer mechanism 58.

  Next, as shown in FIG. 15, the winding end line of this coil 8a is connected to the wire path Mb4 of the insulating bobbin 3b assembled to the winding part UK1 by the operations of the flyer mechanism 58 and the chuck mechanism 51a, and the adjacent winding part. An adjacent connecting wire 43 is formed through the wire path Mb3 of the insulating bobbin 3b assembled to the UK2. In order to shorten the work time, the winding portion UK2 is made to face the flyer mechanism 58 in the operation of forming the adjacent crossover wire 43. Next, the flyer mechanism 58 is turned in the opposite direction to that when it is wound around the winding part UK1, and the coil 8b is wound around the winding part UK2.

  Thus, the winding to the winding parts UK1 and UK2 including the first divided laminated cores 1a and 1b is completed. Subsequently, the winding end line of the coil 8b wound around the winding part UK2 is passed through the wire path Ma4 of the insulating bobbin 3a below the winding part UK2 by the operations of the flyer mechanism 58 and the chuck mechanism 51a (see FIG. 2). Subsequently, it is hooked in a U-phase groove 55U provided in the adjustment hook 55, and is passed through a wire path Ma3 provided in an insulating bobbin 3a on the lower side of the winding part UK3, which becomes a separation connecting wire 41U. In order to shorten the work time, the winding portion UK3 is made to face the flyer mechanism 58 in the operation of forming the separation connecting wire 41U.

  Next, the flyer mechanism 58 is turned in the same direction as when wound around the winding part UK2, and the coil 8b is wound around the winding part UK3. The winding end line of the coil 8b is operated by the flyer mechanism 58 and the chuck mechanism 51a, so that the wire path Mb4 of the insulating bobbin 3b assembled to the winding unit UK3 and the wire of the insulating bobbin 3b assembled to the adjacent winding unit UK4. It passes through the route Mb3 and is defined as an adjacent crossover line 43. In order to shorten the work time, the winding part UK4 is opposed to the flyer mechanism 58 in the operation of forming the adjacent crossover wire 43.

  Next, the flyer mechanism 58 is turned in the same direction as when the winding part UK1 is wound, and the coil 8a is wound around the winding part UK4. The winding end wire 45U of the coil 8a passes through the wire path Mb4 of the insulating bobbin 3b assembled to the winding portion UK4, and is hooked on the binding pin 56 to ensure its length and cut.

  As described above, the winding process to the U-phase winding part group 1U is completed to obtain the U-phase split stator group 10U. The U-phase split stator group 10U that has completed the winding fixed to the chuck mechanism 51a is conveyed to the opposite side as the index table 53 rotates 180 °. Here, the movable claw 522 of the chuck mechanism 51a is closed to the fixed claw 521 side. At this time, each winding part of the V-phase winding part group 1V, which has been put in the chuck mechanism 51b in advance during the winding to the U-phase winding part group 1U, is transported to the flyer mechanism 58 side for the next V-phase. The coil 8 winding process is performed.

  The winding process for winding the coil 8 around the U-phase winding unit group 1U has been described above, but the same applies to the winding of the coil 8 around the W-phase winding unit group 1W. It is only necessary to change to the W-phase groove 55W. For the winding part of the V-phase winding part group 1V, the operation hooked on the adjustment hook 55 is a V-phase groove 55V, and the winding direction of the coil 8 is opposite to the U-phase as shown in FIG. Just good.

  According to the stator, the stator manufacturing method, and the stator winding device according to the first embodiment of the present invention, the separated connecting wires 41U to 41W of different phases without increasing the size of the insulating bobbins 3a and 3b. Interference between adjacent crossover wires 43 can be prevented, and a stator 100 of a rotating electrical machine having high dielectric strength can be manufactured.

  Also, dovetail grooves 11a1 and 11b1 extending in the stacking direction of the split laminated iron cores 1a and 1b are provided in the respective laminated back yoke portions 11a and 11b, and the fixed claws 521 and the movable claws 522 of the chuck mechanisms 51a and 51b of the winding device 50 are provided. The dovetail grooves 11a1 and 11b1 can be positioned and fixed simultaneously using the claw mechanism 520 constituted by As a result, highly reproducible windings and connecting wires can be arranged, high-density coils 8a and 8b are wound at high speed, and the lengths of the separating connecting wires 41U to 41W and the adjacent connecting wires 43 can be finely adjusted. It is possible to manufacture the stator 100 of the rotating electric machine having high dielectric strength.

  In addition, since the adjustment hook 55 has the plurality of grooves 55U to 55W, there is no fear that the separating and connecting wires 41U to 41W are loosened and the insulating coating is damaged in the coil winding process. Further, since the lengths of the separation connecting wires 41U to 41W can be finely adjusted for each phase, the stator 100 having a high dielectric strength is manufactured without interference of the separation connecting wires of different phases even if it is a product. be able to.

Further, the chuck mechanisms 51a and 51b have a straight line B1 connecting the axes of the laminated tooth portions 12a of the two divided laminated iron cores 1a to be assembled and a straight line B2 connecting the axes of the laminated tooth portions 12b of the two divided laminated iron cores 1b. Since the winding portions UK1 to UK4 and the like are positioned so that both pass through the rotation drive shafts C1 and C2, the winding portions are made to face the flyer mechanism 58 at the same position only by rotating the rotation drive shafts C1 and C2. The coil 8 can be wound on all winding parts under the same conditions. Thereby, the adjustment time of the winding apparatus 50 can be shortened.
Further, the length of the winding end line can be finely adjusted by providing the binding pin 56 for securing the length of the winding start line 40U to 40W or the winding end line 45U to 45W of the coil 8 to the chuck mechanisms 51a and 51b. Thus, the stator 100 having high dielectric strength can be manufactured with high productivity without interfering with all the crossover wires.

  The chuck mechanisms 51a and 51b have movable claws 522 that can be opened and closed as many as the number of dovetail grooves 11a1 and 11b1 provided in the split laminated iron cores 1a and 1b, and the fixed claws 521 and the movable claws 522 are connected to the dovetail grooves 11a1, 11b1 is engaged and each winding part is gripped, and the four movable claws 522 are all integrated and can be opened and closed by the same amount at the same time, so that each winding part can be positioned and fixed simultaneously, The winding of the coil 8 with high reproducibility and the arrangement of all the crossovers are possible.

  In addition, the winding device 50 is provided with a clamp mechanism 54 that grips the winding start lines 40U to 40W, and the clamp mechanism 54 is disposed above the rotational drive shafts C1 and C2 of the chuck mechanisms 51a and 51b, so that the coil When the chuck mechanisms 51a and 51b are rotated in order to change the respective winding portions that wind the winding 8, the distance between the clamping mechanism 54 and the winding start portion of the coil 8 does not change. It is possible to prevent deterioration of the insulating film of the conductive wire 6 used in the process.

  The winding device 50 has a horizontal and rotatable index table 53. A plurality of chuck mechanisms 51a and 51b are arranged on the index table 53, and the rotation drive shafts C1 and C2 of the chuck mechanisms 51a and 51b are arranged. Since all the distances from the rotation axis T of the index table 53 are made equal, the divided stator group that has finished the winding of the coil 8 is removed from the winding of the coil 8, and then the coil 8 is wound. The winding unit group to be wound can be put into the winding device 50. Thereby, the winding process can be parallelized, and the productivity of the stator 100 is improved.

  In addition, since the high-density coil 8 can be wound at a high speed by reducing the number of parts, the stator 100 having high dielectric strength can be produced without causing interference between the separate connecting wires 41U to 41W and the adjacent connecting wires 43 of different phases. can do.

  In this embodiment, an example of a stator 100 (armature) of a 10-pole 12-slot three-phase DC brushless motor has been described. However, for example, a 3-phase DC brushless motor having a 20-pole 24 slot, a 30-pole 36 slot, or the like. The same can be applied to the case.

In the present embodiment, the winding start lines 40U to 40W are described as the input terminal side and the winding end lines 45U to 45W are defined as the neutral point side for convenience of description. Even if it is reversed, it is established. By using such an electrical wiring, the number of connection points of the conductive wire 6 is small, and the number of places where there is a risk of contact between the spaced-apart connecting wires 41U to 41W and the adjacent connecting wires 43 can be reduced to the limit, and the shape of the insulating bobbin is complicated Increase in size and size, and in turn, increase in size of the stator 100 can be suppressed.
Note that the winding device and the stator winding method used in the present embodiment can also be applied to an integrated split core that is not a split laminated core.
