The present invention, in order to obtain while maintaining the structure of the rotor yoke to the integral, the permanent magnet rotating electric machine and a wind power generation permanent magnet type synchronous generator capable of reducing the eddy current loss of the rotor It has been made.
Its arrangement comprises a stator 101 having a rotor 100 and the armature winding is wound centrally on the teeth having a plurality of magnetic poles by the permanent magnet 4, the pole pairs of the magnetic poles of the rotor 100 P, the diameter of the rotor 100 and D [m], when the spatial order of the predetermined harmonic component of the armature magnetomotive force of the rotor 100 and the N (a mechanical angle 360 ​​degree to the primary), the, P, D, N is configured so as to satisfy the ((N + P) 1.5 squared) × ((-4) th power of N) × (2 square of P) × D <0.6 (unit m) there.
