Abstract
A dynamo electric machine includes a rotor having magnetic poles with permanent magnets and a stator having armature windings concentratedly wound around teeth. When the number of pole pairs of the magnetic poles of the rotor is P, diameter of the rotor is D (meters), and a spatial harmonic order of a predetermined harmonic component of an armature magnetomotive force of the rotor is N ((N=P to the 1.5power)×(N to the minus 4-th power)×(the square of P)×D<0.6 (in meters).
