摘要：A permanent-magnet electric rotating machine with a concentrated winding
stator, including a stator having a plurality of stator magnetic poles formed so as toextend radially from an annular yoke portion of a stator iron core, and windings mountedon the stator magnetic poles; and a rotor having a permanent magnet with a plurality ofmagnetic poles and rotatably held so as to face the stator through an air gap; whereineach of the stator magnetic poles has a straight shape having a width which is madeconstant over a whole length, small grooves are formed in each of the stator magneticpoles in symmetrical positions on opposite sides and near a top end portion of the statormagnetic pole, a bottom portion of each slot portion defined by adjacent ones of thestator magnetic poles and the yoke is formed triangularly, each of the stator winding isconstituted so that a winding having a predetermined number of turns and winding beingformed so as to be fittable to each of the stator magnetic poles is mounted on thestator magnetic pole through an insulator, and wedges are fitted to the small groovesformed in the stator magnetic poles.
