Abstract
A brushless repulsion motor in which the rotor carries electronic switch circuits for selectively shorting the rotor windings at appropriate times in its rotational cycle. A non-contact reference signal source on the stator enables the electronic circuitry to operate as desired. The disclosed motor arrangements are useful as substitutes for conventional brush-type repulsion motors, universal series motors, synchronous motors, servomotors and stepping motors.
Claims10
A repulsion dynamoelectric machine comprising a stator and a rotor rotatably mounted about a first axis on said stator said repulsion machine without brushes, an AC field winding on one of said stator and rotor for producing a field, a plurality of coils in an armature winding on the other of said stator and rotor adapted to electromagnetically interact with the field of the field winding, electronic switch means connected to said armature winding to substantially short-circuit successive pairs of its coils when they and the field winding are in relative angular positions where the field is effective to induce a current in the armature winding to produce a resultant relative torque on the rotor.
A repulsion motor comprising a stator and a rotor said motor without brushes, means for rotatably mounting said rotor with respect to said stator, a field winding on said stator for producing a field when current is passed through said field winding, a plurality of coils on said rotor for electromagnetically interacting with said field of said field winding, and means for producing only an induced current in said coils for producing a resultant relative rotation between said stator and said rotor.
