Document Type and Number:
WIPO Patent Application WO/2022/239851
Kind Code:
A1
Abstract:
This rotor comprises a plurality of rotor parts (R1, R2) that are arranged side by side in the axial direction. Each of the plurality of rotor parts includes a rotor core (22) and a plurality of permanent magnets (23). Each of the plurality of rotor parts has a plurality of magnetic pole parts (26) and a plurality of magnetic pole boundary parts (Ld). At least one of the plurality of rotor parts has a displacement part (31) on the outer peripheral surface of the rotor core. The displacement part (31) is displaced radially inwards from the magnetic pole center (Ls) of each of a pair of magnetic pole parts adjacent to each other in the circumferential direction toward the magnetic pole boundary part between the pair of magnetic pole parts. The displacement part (31) is provided so as to correspond to at least one of the plurality of magnetic pole boundary parts. The magnetic pole center of at least one rotor part is shifted in the circumferential direction with respect to the magnetic pole center of another rotor part.
