    摘要： A permanent-magnet electric rotating machine (1) with a concentrated winding stator, comprising: a stator (2) having a plurality of stator magnetic poles (51-62) formed so as to extend radially from an annular yoke portion (40) of a stator iron core (4), and windings (5) mounted on the stator magnetic poles; and a rotor (3) having a permanent magnet (21) with a plurality of magnetic poles and rotatably held so as to face the stator through an air gap. Each of the stator magnetic poles (51-62) has a straight shape having a width which is made constant over a whole length, small grooves (42a,42b) are formed in each of the stator magnetic poles in symmetrical positions on opposite sides and near a top end portion of the stator magnetic pole, a bottom portion of each slot portion defined by adjacent ones of the stator magnetic poles and the yoke is formed triangularly. Each of the stator windings (5) is constituted so that a winding having a predetermined number of turns and winding being formed so as to be fittable to each of the stator magnetic poles is mounted on the stator magnetic pole through an insulator (6), and wedges (13) are fitted to the small grooves (42) formed in the stator magnetic poles.
