PERMANENT MAGNET ROTOR AND PERMANENT MAGNET ROTARY ELECTRIC MACHINE

WIPO Patent Application WO/2024/034149

A1

A permanent magnet rotor (100) according to an embodiment of the present invention comprises: a rotor core (120) including a rotor shaft, a first outer through hole (121) and a second outer hole (122) attached to the rotor shaft and made so as to form a pair with each other on the outside in the radial direction in each of magnetic poles, and a first inner through hole (124) and a second inner through hole (125) made so as to form a pair with each other further inward in the radial direction than the outer through holes; and a first outside magnet (131), a second outside magnet (132), a first inside magnet (133), and a second inside magnet (134) accommodated in each of the through holes. The outer opening angle θa of the first outside through hole (121) and the second outside through hole (122) is larger than the inner opening angle θb of the first inner through hole (124) and the second inner through hole (125).
