Abstract

Official abstract text for this publication.

Provided is a stator including a stator core composed of an annular core back and teeth projecting from the inner circumference side of the core back, and an end plate for clamping and pressing at least one end side of the core back and the teeth in the axial direction.

First claim

Opening claim text (preview).

The invention claimed is: 1. A stator, comprising: a stator core composed of a separate annular core back and multiple teeth projecting from an inner circumference side of the core back; and an end plate for clamping and pressing the core back and the teeth in an axial direction, wherein a first face of the end plate that faces the stator core for clamping and pressing the core back projects further towards an axial center of the stator core than does a second face of the end plate that faces the stator core for clamping and pressing the teeth. 2. The stator according to claim 1 , wherein the core back has a larger iron loss than that of the teeth. 3. The stator according to claim 1 , wherein the core back has a larger iron loss than that of the teeth, and a length of the core back in the axial direction before the core back is clamped and pressed with the end plate is longer than that of the teeth before the teeth are clamped and pressed with the end plate.
