Title:
ROTOR AND ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/080010
Kind Code:
A1
Abstract:
The present invention is configured such that end portions of a permanent magnet (23) protrude as protruding portions (23x1, 23y1) from axial end surfaces (22c, 22d) forming a flat surface of a rotor core (22), and the magnetic flux of an embedded magnet portion (23m) of the permanent magnet (23) located within the rotor core (22) is prevented from leaking from the axial end surfaces (22c, 22d) of the rotor core (22) as much as possible.
