Title:
ROTOR FOR MOTOR, AND MOTOR USING SAID ROTOR
Document Type and Number:
WIPO Patent Application WO/2023/119459
Kind Code:
A1
Abstract:
The present invention provides a rotor that can rotate at a high-speed without a frame body, as a result of individual wedges being embedded between split rotor cores. Since it is not necessary to arrange components on the inner diameter side of the rotor core, the present invention can also be applied to an outer rotor. A rotor (1) comprises: a rotor core (3) in which split rotor cores (3a) are disposed circumferentially, the split rotor cores having permanent magnets (2) embedded therein and being divided in the circumferential direction; a holding member (4) having a cylindrical shape, the inner diameter surface thereof being in contact with the outer circumferential surface of the rotor core (3); and individual wedges (5) embedded between the split rotor cores (3a).
