STATOR CORE
First Claim
1. A stator core comprising:
- a cylindrical base portion; and
a plurality of teeth that extend inward in a radial direction from the cylindrical base portion and that are arranged at predetermined intervals in a circumferential direction,wherein a slot, into which a coil is inserted, is formed between each pair of the teeth that are adjacent to each other in the circumferential direction, andwherein a cutout is formed in a part of each of the teeth near one end surface of the tooth, the part facing an inner surface of a bent portion of the coil, the cutout having a predetermined length in the circumferential direction, a predetermined length in the radial direction, and a predetermined length in an axial direction.

Abstract
A stator core of a rotating electric machine, includes a base, teeth, slots, and cutouts. The base includes a through-hole having a substantially cylindrical shape surrounded by an inner circumferential wall around a center axis of the substantially cylindrical shape. Teeth are arranged around the center axis and extending along a radial direction of the substantially cylindrical shape from the inner circumferential wall toward the center axis. Each of the teeth has a first end surface and a second end surface opposite to the first end surface in the center axis. Each of the slots is defined between a tooth and another tooth adjacent to the tooth among the teeth such that a coil is to be provided into each of the slots. Each of the cutouts is provided in the first end surface to face an inner surface of a bent portion of the coil.
