ABSTRACT:
A dynamo-electric machine comprises a stator having a plurality of salient poles wound with a coil, and a rotor fixed with a plurality of permanent magnets and disposed to rotate freely on an outer circumference of the stator. Salient poles becoming in-phase are arranged adjacently in a circumferential direction and these adjacent salient poles are disposed oppositely to the permanent magnets of different polarity at the same electric angle. These salient poles have coils wound in reverse directions. An angle between adjacently salient poles is set at 360°/N for in-phase, and an angle θ2 between adjacently salient poles is set at θ1+θ1
umber of phases P for out-of-phase, where N is the number of poles of the permanent magnets, and the number of phases P×(θ1+θ2) is set at 180° or less.
