Title:
ROTOR AND ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/080110
Kind Code:
A1
Abstract:
The present invention is configured so that end parts of a permanent magnet (23) protrude, as projecting parts (23x1, 23y1), from axial end faces (22c, 22d) which form flat surfaces of a rotor core 22, and leakage of the magnetic flux of an embedded magnet part (23m) of the permanent magnet (23), which is positioned inside the rotor core (22), from the axial end faces (22c, 22d) of the rotor core (22) is minimized as much as possible.
