Abstract
A rotary electric machine includes inner and outer rotors each including permanent magnets, and a stator including stator coils, disposed between the inner and outer rotors. The inner rotor further includes outer surface portions serving as a yoke portion of an outer magnetic circuit for magnetic flux synchronous with the outer rotor, and the outer rotor further includes outer portions each located on an outer side of one of the outer permanent magnet, and arranged to serve as a yoke portion of an inner magnetic circuit for magnetic flux synchronous with the inner rotor.
