1. A double-stator rotating electric machine comprising:
a rotor; an outer stator disposed radially outside the rotor with an outer gap formed therebetween, the outer stator having a first multi-phase coil wound thereon; and an inner stator disposed radially inside the rotor with an inner gap formed therebetween, the inner stator having a second multi-phase coil wound thereon, wherein the outer stator is configured to form a plurality of magnetic poles upon energization of the first multi-phase coil, the inner stator is configured to form a plurality of magnetic poles upon energization of the second multi-phase coil, the number of the magnetic poles formed by the outer stator is equal to the number of the magnetic poles formed by the inner stator, each of the magnetic poles formed by the outer stator is located at the same circumferential position as and has an opposite polarity to a corresponding one of the magnetic poles formed by the inner stator, thereby causing magnetic flux to flow in a radial direction of the rotor, and the rotor has a plurality of yoke portions each of which radially extends so as to form a magnetic flux passage magnetically connecting the outer and inner stators. |
