Document Type and Number:
WIPO Patent Application WO/2020/261420
Kind Code:
A1
Abstract:
This rotor (2) has at least one first permanent magnet (21) and a second permanent magnet (22), and has 2n magnetic poles (n is a natural number). The at least one first permanent magnet (21) forms a portion of the outer circumferential surface of the rotor (2) and is magnetized so as to have pole anisotropy. The second permanent magnet (22) is adjacent to the at least one first permanent magnet (21) in the circumferential direction of the rotor (2), and holds magnetism lower than the magnetism of the at least one first permanent magnet (21). The second permanent magnet (22) holds 3 x 2n magnetic poles.
