Rotary electric machine, rotary electric machine unit, and electric vehicle

A rotary electric machine comprising:

• a cylindrical rotor including at least one first permanent magnet and at least one second permanent magnet, for each pole;
• and
• a cylindrical stator including a stator core and a winding and placed with a gap between the stator and the rotor, wherein
• the first permanent magnet is placed at a position advanced in a forward rotation direction of the rotor with respect to a d axis of the rotor, and the second permanent magnet is placed at a position delayed in the forward rotation direction of the rotor with respect to the d axis of the rotor,
• on the basis of a difference between heat generation levels of the first permanent magnet and the second permanent magnet which generate heat through operation of the rotary electric machine, one of the first and second permanent magnets is defined as a high-heat-generation magnet, and the other is defined as a low-heat-generation magnet, and
• the rotor is formed with heat release performance of the high-heat-generation magnet made greater than heat release performance of the low-heat-generation magnet, and is cooled by heat transfer via a fluid.
