Abstract
A reinforcement component includes a ring part extending in a circumferential direction of a stator, and a plurality of protrusions arranged to be spaced from each other in the circumferential direction of the stator and each protruding beyond the ring part. Each of the protrusions of the reinforcement component is fixed between inner circumferential flanges of insulators adjacent in the circumferential direction of the stator. A plurality of teeth are connected with each other throughout a full circumference of the stator by means of the ring part of the reinforcement component, so that the ring rigidity of the stator can be improved.
Claims6
A stator of a rotary electric machine, comprising:
- a stator core that includes an annular yoke extending in a circumferential direction and a plurality of teeth arranged to be spaced from each other in the circumferential direction and each protruding to a radial inner side of the yoke;
- insulators that are fitted to the respective teeth;
- coils that are wound around the respective teeth across the respective insulators;
- and
- a reinforcement component that includes a ring part extending in the circumferential direction and a plurality of protrusions arranged to be spaced from each other in the circumferential direction and each protruding beyond the ring part,
- wherein the protrusions of the reinforcement component are fixed between radial inner ends of the insulators adjacent in the circumferential direction, or between radial inner ends of the teeth adjacent in the circumferential direction.
