WIPO Patent Application WO/2023/144919

Kind Code:

A1

Abstract:

A rotor (1) has a rotary shaft (10), a first resin magnet (20) that is supported by the rotary shaft (10), and a plurality of second resin magnets (31) that have stronger magnetic poles than the first resin magnet (20) and are provided to a first outer circumferential surface (20c) that is the surface of the first resin magnet (20) that faces outward in the radial direction.
