Abstract
A brushless repulsion motor which includes a stator and rotor rotatably mounted on the stator is provided. The stator and rotor are contained within a first housing, the stator having at least one pair of poles, a field winding on the stator for producing a field on the stator, and a plurality of coils on the rotor adapted to electromagnetically interact with the field of the stator winding. Switches are located on the rotor shaft outside the first housing to selectively short successive ones of the coils when the coils are in a preferred angular position relative to the stator poles. Thus, the stator field is effective to induce a current in the rotor and produce a resultant relative rotation between the rotor and the stator which can be controlled by non-contact signaling means which activate the switches.
