Abstract: In a rotating electric machine, an axis direction width of a rotor core arranged at an end of a load side of the rotating shaft is set to be ?, an axis direction width of a rotor core arranged at an opposite side end of the load side is set to be ?, a distance from a support part at the load side to the rotor core at the load side is set to be ?, and a distance from a support part at the opposite side of the load side to a rotor core at the opposite side of the load side is set to be ?. In a case of ?>?, ??? is satisfied, and in a case of ?<?, ??? is satisfied. Thereby, the vibration of the rotor can be suppressed effectively.

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.
