PROBLEM TO BE SOLVED : To provide a rotary electric machine with superior characteristics, in the rotary electric machine which has a stator of the so-called concentrated winding structure where winding is applied concentratedly to the teeth of a stator core, and besides uses a permanent magnet for its rotor.
SOLUTION : The rotary electric machine has a stator 230, which has a stator core 232 and coils 233 that are wound concentratedly around individual teeth 237 of the stator core 232, and a rotor 250, which has a rotor core 252 and a plurality of permanent magnets 254 and 256 held by the rotor core 252 and is held rotatably via an air-gap from the teeth 237 of the stator 230. The permanent magnets 254 and 256 are rare earth permanent magnets, and rare earth magnetic powder is bound by SiO2.
