Abstract
Provided is a rotating electric machine that combines high efficiency and high strength reliability. The rotating electric machine includes: a stator having a coil and a stator core; and a rotor opposed to the stator with a gap intervening between the rotor and the stator, the rotor having permanent magnetsand a rotor core. The rotor is configured such that the permanent magnets are buried in V-shape at hole-shaped slotsdisposed in the rotor core to form one pole, and the pole is formed in plurality in a circumferential direction. Each of the slots is an open slot partially opened toward an outer circumference of the rotor core. The slot is provided with a hook-shaped structureto support corresponding one of the permanent magnets in an open portion thereof.
