Abstract
A stator that includes stator windings wound around teeth. A rotor includes: a rotor core; rotor windings wound around main salient poles of the rotor; and a diode serving as a magnetic characteristic adjustment portion that causes magnetic characteristics produced on the main salient poles by electromotive forces induced in the rotor windings to differ in the circumferential direction of the rotor. The rotor has auxiliary salient poles that are each protruded from a side surface of each main salient pole in the circumferential direction. In each of rotor slots formed between the main salient poles adjacent to each other in the circumferential direction, the auxiliary salient poles adjacent to each other in the circumferential direction are connected to each other within the rotor slot. In each rotor slot, at least a portion of the rotor windings is disposed radially inside the auxiliary salient poles.
