A dynamo-electric machine 1 comprising a stator 3 having a plurality of salient poles 14 wound with a coil 5, and a rotor 2 fixed with a plurality of permanent magnets 4 and disposed to rotate freely on the outer circumference of the stator 3. Salient poles U1 and U2 becoming in-phase are arranged adjacently in the circumferential direction and adjacent salient poles U1 and U2 of in-phase are disposed oppositely to the permanent magnets of different polarity at the same electric angle. Salient poles U1 and U2 of in-phase have coils wound in the reverse directions. The angle &thetas;1 between adjacently salient poles is set at 360 DEG / N for in-phase, and the angle &thetas;2 between adjacently salient poles is set at &thetas;1 + &thetas;1 / number of phases P for out-of-phase, where N is the number of poles of the permanent magnets, and the number of phases P x (&thetas;1 + &thetas;2) is set at 180 DEG or less. <IMAGE> |
