Abstract
In an electrical rotating machine, two rotors are provided, each rotor has a plurality of permanent magnets along its peripheral direction thereof, arranged coaxially with the other rotor, and is driven by means of a compound current supplied to stator coils and a single stator has a plurality of stator coils through which the compound current is caused to flow, one of the rotors exhibiting a forward saliency characteristic and the other rotor exhibits a reverse saliency characteristic.
