Document Type and Number:
WIPO Patent Application WO/2023/026641
Kind Code:
A1
Abstract:
This inner rotor 1 comprises a rotor body 2, a polar anisotropic magnet 4 and a plurality of magnetic bodies 3. The rotor body 2 rotates about a rotation axis A1. The polar anisotropic magnet 4 forms a plurality of magnetic poles 41 arranged in the circumferential direction about the rotation axis A1 and is provided on an outer circumferential surface of the rotor body 2. The plurality of magnetic bodies 3 are disposed on the outer circumferential surface of the polar anisotropic magnet 4 at positions respectively corresponding to the plurality of magnetic poles 41.
