Abstract
A rotary electric machine includes a stator that creates a rotating magnetic field, and a rotor around which a rotor winding is wound so that induced electromotive force is created by a harmonic component of the rotating magnetic field, and in which a magnetic pole is created through the induced electromotive force. The stator has an auxiliary pole that is a leading portion that leads the harmonic component from the stator to the rotor.
Claims5
A rotary electric machine comprising:
- a stator that creates a rotating magnetic field;
- and
- a rotor around which a coil is wound so that electromotive force is created in the coil by a harmonic component of the rotating magnetic field, and in which a magnetic pole is created through the electromotive force, wherein the rotor has a leading portion that leads the harmonic component from the stator to the rotor.
