Stator for rotating electrical machine and rotating electrical machine
View Patent ↗A component for a rotating electrical machine includes a stator, a winding, and a covering material. The stator has a stator core with a plurality of slots. The winding is inserted into one slot. The covering material covers the winding. The winding has a molten metal junction. The covering material has a non-bending part and a bending part. The bending part has a contact area that is smaller than an area between the non-bending part and the winding. The bending part is provided between the molten metal junction and the portion of the winding inserted in the one slot.
1. A stator for a rotating electrical machine comprising:
a stator core with a plurality of slots;
a winding inserted into the plurality of slots; and
a covering material that covers the winding, wherein
the winding has a molten metal junction,
the covering material has a non-bending part and a bending part,
the bending part of the covering material has a contact area with the winding that is smaller than a contact area between the non-bending part and the winding, and
the bending part is provided between the molten metal junction and the portion of the winding inserted in one slot of the plurality of slots.
2. The stator according to claim 1 , wherein the bending part is provided on the axial end face of the covering material.
3. The stator according to claim 1 , wherein the bending part is provided in a region that is viewable from an axial direction.
4. A rotating electric machine comprising:
the stator according to claim 1 ; and
a rotor rotatably arranged over the stator core through a given gap.
