ROTARY ELECTRIC MACHINE

Abstract:

A first magnet, a second magnet, a fourth magnet, and a third magnet are retained on a rotor of a rotary electric machine in this order alongside one another in a circumferential direction. Magnetic fields of the first magnet and the fourth magnet are oriented in radial directions of a stator. Magnetic fields of the second magnet and the third magnet are oriented in circumferential directions of the stator. When the rotor is viewed in plan from above or below, a ratio of a total surface area of the first magnet and the fourth magnet to a total surface area of the second magnet and the third magnet is S14:S23=1:0.2 to 1:1.
