The part is integrally formed. The winding position regulating protrusion is configured to regulate the winding position of the winding so that the winding portion does not come into contact with the pair of extended portions of the magnetic pole portion covered by the slot insulating member.

入する作業が容易になる。When the winding position regulating protrusion is provided at a position adjacent to the tip of each salient pole in this way, the winding is not formed in the vicinity of the pair of extended portions of the magnetic pole or the slot insulating member is used. Since the winding portion can be formed so that the winding portion does not contact the pair of extended portions of the covered magnetic pole portion, it is possible to prevent the winding portion from being formed on the magnetic pole side of the salient pole with respect to the position regulating protrusion. As a result, a space for arranging the wedge can be formed between the two extending portions of the two adjacent salient poles facing each other in the circumferential direction and the winding portions respectively wound on the two adjacent salient poles. In the present invention, since the wedge is arranged in this space, that is, both ends of the wedge located in the circumferential direction are fitted in this space, the work of inserting the wedge into the opening of the slot becomes easy.

材の形状・構造が複雑になることがない。Further, in particular, when the winding position restricting protrusion is integrally formed with the slot insulating member, the slot insulating member and the winding position restricting protrusion can be molded together, so that the cost can be reduced and the parts management is troublesome. It doesn't take. At both ends of the slot insulating member in the stacking direction, the slot insulating member is located on the base side of the plurality of protrusions and protrudes in one direction of the stacking direction away from the laminated iron core and surrounds the bases of the plurality of protrusions. If there is an annular collar portion formed on the magnetic pole portion and an arc-shaped collar portion that is located on the magnetic pole portion and projects away from the laminated iron core in one direction of the lamination direction, the winding position regulation It is preferable that the protrusion is provided so as to be continuous with the arc-shaped collar. With this configuration, the shape and structure of the slot insulating member will not be complicated even if the winding position regulating protrusion is integrally formed with the slot insulating member.

In such a case, the windings are projected close to the pair of extended portions of the magnetic pole portion at the portions covering both end faces of the slot insulating member that are located in the laminating direction of the steel plates of the salient poles and are located in the laminating direction. A winding position regulation member having a winding position regulation protrusion that regulates the winding position of the winding so as not to form a portion is arranged. More specifically, the winding position regulating projections are provided at the portions covering both end faces of the slot insulating member that are located in the laminating direction of the steel plates of the plurality of salient poles, and projecting on both sides in the laminating direction. Place the members. Then, the winding position regulating member may be configured to regulate the winding position of the winding so that the winding portion does not come into contact with the pair of extended portions of the magnetic pole portion covered by the slot insulating member. When the winding position regulating member formed separately from the slot insulating member is used, the existing slot insulating member and the winding position regulating protrusion can be used in combination.

The two slot insulators 4A and 4B are fitted into the laminated iron core 2 from both sides in the laminating direction of the laminated iron core 2. In particular, in the slot insulating member 4 of the present example, the winding position regulating protrusion 7 is formed on the outward surface side in the laminating direction of the laminated core 2 of the laminated structure at the boundary between the front end side collar portion 4a and the body portion 4c.
Are integrally formed. In other words, the slot insulator 4A that constitutes the slot insulating member 4
And 4B, each of the salient poles 3 has a pair of extension portions 3b1 (a pair of extension portions 3b1 of the magnetic pole portion 3b) projecting outward in the stacking direction at portions 4d respectively covering both end surfaces of the salient poles 3 located in the stacking direction. Portion 4a of slot insulating member 4 for covering
1) so that the winding portion 6 is not formed in the vicinity thereof, or the pair of extended portions 3b1 (the pair of extended portions 3b1) of the magnetic pole portion 3b.
A winding position regulating projection 7 is integrally formed to regulate the winding position of the winding so that the winding portion 6 does not come into contact with the portion 4a1) of the slot insulating member 4 that covers b1. Since the winding position regulating protrusion 7 is formed integrally with the tip side flange 4a, it is easy to mold. The winding position regulation protrusion 7
The width dimension is substantially the same as that of the portion 4d that covers the end face of the laminated core 2 located in the laminating direction. Further, the projecting dimension of the winding position regulating protrusion 7 in the direction toward the side of the base-side flange 4b is such that the winding portion 6 is provided between the portion 4a1 of the slot insulating member 4 covering the pair of extended portions 3b1 of the magnetic pole portion 3b and the winding portion 6. , The dimensions of which can form a space into which the wedge 8 can be fitted. Specifically, both ends of the wedge 8 located in the circumferential direction are wound so that a space can be inserted between the portion 4a1 of the slot insulating member 4 and the winding portion 6 and is sandwiched therebetween. The projecting dimension of the line position regulating projection 7 in the direction toward the base-side flange 4b is defined. Further, the projecting dimension of the winding position regulating projecting portion 7 projecting outward in the stacking direction is the same as the projecting dimension of the tip side flange portion 4a, and as shown in FIG. It is set to be longer than the protruding size of the part.

巻線の巻回位置を規制している。In this state, a winding conductor is wound around each salient pole 3 of the laminated iron core 2 via a slot insulating member 4 to form a winding portion 6. When forming the winding portion 6, nozzles of a winding machine are inserted into the slots 5 on both sides of the salient pole 3 to directly wind the winding conductor. At this time, since the winding position regulation protrusion 7 is present, the winding position of the winding is regulated so that the winding portion 6 does not protrude toward the entrance side of the slot 5 and the space for inserting the wedge 8 is not narrowed. ing.

ものを用いることができる。After the winding process is completed, the wedge 8 made of a sheet-shaped or plate-shaped insulating member opens in the inner peripheral side (radially inner side) of the slot 5 between the adjacent salient poles 3 and extends in the stacking direction. The slot 5 is inserted through one of two openings that are open to the outside in the stacking direction of the slot 5 (the axial direction of the shaft of the rotor) so as to close the opening. As described above, the insertion work of the wedge 8 is regulated by the winding position regulating protrusion 7 so that the winding portion 6 does not project toward the inlet side of the slot 5, that is, the opening extending in the stacking direction. It can be done easily. As the wedge 8, for example, a glass fiber group formed of epoxy resin in a sheet shape or a plate shape can be used.
