Title:
ROTATING ELECTRICAL MACHINE STATOR AND MANUFACTURING METHOD FOR ROTATING ELECTRICAL MACHINE STATOR
Document Type and Number:
WIPO Patent Application WO/2022/203002
Kind Code:
A1
Abstract:
Disclosed is a rotating electrical machine stator for driving a vehicle, the rotating electrical machine stator comprising: a stator core that is formed from a first metal material which is a magnetic body; a bonding layer that is formed on at least part of the outer circumferential surface of the stator core and includes a second metal material which is a non-magnetic body; and a stator support that is integrally bonded to the outer circumferential surface of the stator core and is formed from the second metal material. The stator core has, in a first section on a circumferential-direction part of the axial end of the outer circumferential surface, a recess that is recessed further radially inward than a second section and that extends in the axial direction. The stator support is located on the outer circumferential edge of the axial end surface of the stator core in the circumferential-direction second section, and is located inside the recess in the circumferential-direction first section.
