This dynamo-electric machine comprises a rotor and a stator. The rotor has circumferentially disposed permanent magnets of n poles. The stator comprises circumferentially disposed m slots and teeth, and r-phase coils wound on the teeth. The coils have s phase coils serially connected in order from the first to the sth. The ratio of the number of poles n of the permanent magnets and the number of slots m is n:m = (3±1):r. The first phase coil of each phase is connected to an inverter, the sth phase coil is connected to a neutral point, and the phase coils are disposed, with respect to the teeth, so that the first phase coils are not adjacent to each other in the circumference direction.
