摘要： An electric rotary machine has a concentrated winding stator and a rotor facing the stator with a gap therebetween. The stator has M number of stator magnetic poles extending in the radial direction from an annular yoke, pole pieces each extending in the circumferential direction of the rotor from the tip end of each of the stator magnetic poles, and windings wound around the stator magnetic poles. The rotor having a permanent magnet with P number magnetic poles, wherein P:M=6n−2:6n, or P:M=6n+2:6n, where n is an integer not less than 2, and the figure of each of the pole pieces is so determined that a gap formed between the pole piece and the rotor is increased going toward the both ends of the pole piece.
