A double-stator rotating electric machine includes a rotor, an outer stator disposed radially outside the rotor with an outer gap formed therebetween, and an inner stator disposed radially inside the rotor with an inner gap formed therebetween. The outer stator has an outer multi-phase coil wound thereon, and the inner stator has an inner multi-phase coil wound thereon. Moreover, the inner gap formed between the inner stator and the rotor is set to be larger than the outer gap formed between the outer stator and the rotor.
