Document Type and Number:
WIPO Patent Application WO/2023/085216
Kind Code:
A1
Abstract:
The present invention provides a rotor that is for a motor, that enables reduction in use amount of magnets, and that enables relaxation of stress occurring at shrink-fitting of a shaft. A rotor (10) is provided so as to be rotatable about the rotation axis (C), and comprises a first magnet (41), a second magnet (42), and a third magnet (43). When viewed along the rotation axis (C), the first magnet (41) and the second magnet (42) extend from the inner side to the outer side of the rotor (10), and have a tabular shape. The third magnet (43) is disposed between the inner side end of the first magnet (41) and the inner side end of the second magnet (42), and has a shape projecting toward the inner side when viewed along the rotation axis (C). When viewed along the rotation axis (C), the thickness of the third magnet (43) at the central portion in the circumferential direction of the rotor (10) is smaller than the thickness of the first magnet (41) and the second magnet (42).
