1. An electronic motor that comprises, in combination, an armature winding having an even number of coils connected in a closed-loop configuration, an even number of switching devices connected to conduct electric current between a power source and the nodes of the armature winding, a field electromagnetically coupled to the armature, magnetic coupling means electrically connected serially through said switching devices to said coils to introduce commutation voltages through said electrical connection to the coils in the armature winding, the magnitude of commutation voltages thereby introduced being independent of motor speed, and means for initiating commutation of each coil of the winding.
