<p>An electric motor or other electric rotating machine in which certain of the stator poles are of hardened magnetic material to provide the machine with a unidirectional self-starting characteristic. In certain preferred embodiments the housing for the motor is of nonconductive material, and two of the stator pole pieces protrude through the housing and serve as electrical terminals. The housing encloses a spool or bobbin which supports the energizing winding for the motor as well as a reduction gear train which advantageously is mounted on one of the flanges of the bobbin.</p> |
