PURPOSE:To enable obtaining the output of little waveform distortion and small form factor by winding an auxiliary winding in empty slots provided on a stator side. CONSTITUTION:An auxiliary winding WSC is wound in empty slots S1-S4 on a stator 22 side arranged in the vicinity of the pole width (w) of a rotor 21 of two-pole structure and with the space (d) wider than said pole width (w) so as to be wound in the vicinity of the diagonal position of a pole angle thetain the rotor 21 and outward of said diagonal position of the pole angle theta. A main output winding WMC and an excitation winding WEC are also wound on a stator 22.
