Title:
ROTARY ELECTRIC MACHINE, ROTOR FOR ROTARY ELECTRIC MACHINE, AND METHOD FOR MANUFACTURING ROTOR FOR ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/182027
Kind Code:
A1
Abstract:
In the present invention, the cross‐sectional shape of each of projection parts is set to be a rectangular shape in which the axial length is longer than the circumferential length so as to be easily detected. Further, recess formation locations, where a plurality of recess parts are formed, are provided in the inner circumference of a cylindrical part, at positions corresponding to the projection parts. The axial-directional intermediate position and the principal-directional intermediate position of each of the projection parts substantially coincide with the axial-directional intermediate position and the circumferential intermediate position of the corresponding recess part. In addition, the axial length of each of the recess parts is longer than the axial length of the corresponding projection part, and the circumferential length of the projection part substantially coincides with the circumferential length of the recess part. With this dimensional relationship as well, it is possible to increase the height of the projection parts and to improve the shaping accuracy of the projection parts.
