Stator core
First Claim
1. A stator core comprising:
- a cylindrical base portion having a center axis; and
a plurality of teeth that extend inward in a radial direction with respect to the center axis from the cylindrical base portion and that are arranged at predetermined intervals in a circumferential direction around the center axis, the cylindrical base portion and the plurality of teeth having a first end surface and a second end surface opposite to the first end surface in an axial direction along the center axis,wherein a slot, into which a coil is inserted, is formed between a first tooth and a second tooth among the plurality of teeth, the first tooth and the second tooth being adjacent to each other in the circumferential direction,wherein a cutout is formed at a first part of the first tooth, the first part being provided on the first end surface, the first part facing an inner surface of a bent portion of the coil,wherein the cutout does not extend to the second end surface of the first tooth, andwherein an additional cutout is not formed at a second part of the second tooth, the second part being provided on the first surface of the second tooth and facing the first part in the circumferential 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.
