PROBLEM TO BE SOLVED: To provide a rotating electric machine which increases its utilization factor of DC power supply voltage. SOLUTION: In a rotating electric machine equipped with a stator (2) in which a plurality of coils are wound, and a plurality of rotors (3, 4) which are arranged coaxially with the stator and are driven by a compound current, at least one of symmetrical N-phase ACs which form the compound current does not have any voltage or current phase difference of 180 degrees at an electrical angle.
