Abstract:
An object is to obtain a rotary electric machine, capable of reducing an eddy current loss which is caused in a magnet member provided in a stator. A rotor and a stator which is arranged to face to the rotor in a radial direction of the rotor are provided. The stator has a stator core, a stator coil, and a magnet member. The stator core has a core back and teethes, and the teethes protrude from the core back toward the rotor and are arranged along a circumferential direction. The stator coil is wound to each of the plurality of teethes, and is arranged in a slot formed between teethes lying next to each other in the circumferential direction. The magnet member is formed of a plurality of permanent magnets in each of the teethes.
