<p>A self-starting unidirectional electric motor in which a pair of auxiliary stator pole members are angularly spaced from the main stator poles and are provided with a magnetic return path having a reluctance which is less than the reluctance of the return path for the main stator poles. When the field coil of the motor is deenergized, the rotor consistently assumes a favorable starting position in which each rotor pole is opposite one of the auxiliary pole members. In several advantageous embodiments the housing for the motor is fabricated from nonconductive, nonmagnetic material, and the main stator poles serve as the motor's electrical terminals.</p> |
