Abstract
A rotary electric machine includes a rotor core, a stator, a field yoke, and a field winding. The rotor core is fixed to a rotary shaft, which includes a magnetic body for forming a magnetic path, and magnetic salient poles. The stator has teeth and a stator winding wound around the teeth by concentrated winding. A slot is formed between adjacent ones of the teeth in a circumferential direction. The field yoke magnetically connects the stator and the magnetic body. The field winding is located in proximity to at least one of the winding ends of the stator winding in an axial direction of the rotary shaft. The field winding generates a magnetic pole on the magnetic salient poles when energized.
