ABSTRACT:
A pair of electromagnets having ferromagnetic cores with end adjacent a toothed ferromagnetic rotor are energized to induce temporary magnetic poles in the respective rotor teeth. A drive circuit selectively applies current to each electromagnet to effect rotational force on the rotor poles. Three changes in magnet current rotate the rotor to three successive stable positions, the third position being achieved when both magnets are energized to complete one step of the motor and then poles are again induced to start another step if desired. The magnetic properties of the rotor and cores are selected to insure that the pole strength in the teeth will be retained during the changes in electromagnet current.
