Title:
PERMANENT MAGNET-TYPE ROTARY ELECTRICAL MACHINE AND MAGNET POSITIONING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/286760
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a permanent magnet-type rotary electrical machine in which magnet positioning is improved. A permanent magnet-type rotary electrical machine (10) comprises: a stator (12); and a rotor (11) disposed radially outside the stator (12). The rotor (11) has: a rotor yoke (17) which faces the stator (12) with a gap therebetween; a permanent magnet (19) disposed on, among the surfaces of the rotor yoke (17), an opposing surface that faces the stator (12); and a plate member (20) for positioning the permanent magnet (19) in the circumferential direction. The opposing surface has a slit (18c) that is recessed radially outward. The plate member (20) has a fitting part (20a) fitted in the slit (18c) so as to have a fixed circumferential position, and a projection part (20b) projecting radially inward from the fitting part (20a). The circumferential end of the permanent magnet (19) comes into contact with the projection part (20b).
