PURPOSE:To facilitate manufacture of a stator winding by approximately equalizing the shape of a junctioned narrow magnetic pole and an auxiliary projecting piece to the shape of a wide magnetic pole, and winding stator windings, respectively, around a first coupling iron core and a second coupling iron core being separated in the diametrical direction. CONSTITUTION:A first coupling iron core 25a magnetically couples the center of a wide magnetic pole 23, formed in the shape to become approximately symmetrical in front and rear in the rotational direction of a permanent magnet rotor 10, with a yoke 31, and on it a stator winding 21 is wound, and a second coupling iron core 25b is provided at the position which makes an angle of 180 deg. in the rotational direction of the permanent magnet rotor to the first coupling iron core 25a, and magnetically couples one end of a narrow magnetic pole 24 with the yoke 31, and on it a stator winding 21 is wound. An auxiliary projecting piece 26 is coupled on the side of one end of the narrow magnetic pole 24, and is arranged along the periphery of the permanent rotor 10, and the shape of the jointed narrow magnetic pole 24 and the auxiliary projecting piece 26 is approximated to the shape of the wide magnetic pole 26. |
