ABSTRACT:
In this pulse driven motor, electromagnetic stators are mounted on the outside of an annular hollow nonferrous cage. The stators are "U" shaped and mounted with the open end of the "U" facing toward the motor shaft. The rotor is a dual disk assembly. Each disk has a plurarity of permanent magnets mounted along its outer edge. The stator yokes on the cage cross-bars and the rotor disks on the shaft are positioned so that the rotor magnets can pass through the yoke gaps. The angular displacement of the rotor disks and the respective placement of the pick-up probes generates a sequential stream of pulses which upon amplification drives the motor stators.
