Solid-state commutator direct current motor employing hall effect elements

Claim 1

AN ELECTRIC MOTOR ENERGIZABLE FROM A SOURCE OF UNIDIRECTIONAL POTENTIAL COMPRISING: (A) A ROTOR MEMBER HAVING MAGNETIC POLES OF OPPOSITE POLARITY THEREON; (B) A STATOR MEMBER, AN EVEN NUMBER OF ARMATURE WINDINGS POSITIONED IN SAID STATOR MEMBER IN TORQUEPRODUCING RELATION WITH SAID ROTOR; (C) A PLURALITY OF SOLID-STATE SWITCHING DEVICES EACH HAVING CONTROL MEANS FOR RENDERING ITS ASSOCIATED SWITCHING DEVICE CONDUCTIVE, EACH OF SAID SWITCHING DEVICES CONTROLLING THE CONNECTION OF A RESPECTIVE ONE OF SAID WINDINGS TO A SOURCE OF UNIDIRECTIONAL POTENTIAL SO THAT UNIDIRECTIONAL CURRENT WILL FLOW IN EACH OF SAID WINDINGS WHEN ITS RESPECTIVE SWITCHING DEVICE IS CONDUCTING; (D) A PAIR OF HALL EFFECT GENERATORS FOR EACH DIRECTION OF MOTOR ROTATION POSITIONED TO SENSE FLUX EMANATING FROM SAID MAGNETIC POLES; (E) MEANS FOR APPLYING ENERGIZING ELECTRICAL CURRENT TO ONE PAIR OF SAID HALL GENERATORS; AND (F) MEANS ASSOCIATED WITH EACH OF THE HALL EFFECT GENERATORS OF SAID PAIR FOR APPLYING A GATING SIGNAL TO THE CONTROL MEANS OF A FIRST SWITCHING DEVICE TO ESTABLISH CURRENT FLOW WITHIN THE ARMATURE WINDINGS OF SAID MOTOR TO PRODUCE AN ARMATURE FIELD IN A FIRST DIRECTION WHEN SAID HALL EFFECT GENERATOR IS UNDER THE COINCIDENT INTER-ACTION OF ITS APPLIED ENERGIZING CURRENT AND ROTOR FLUX OF A FIRST POLARITY AND FOR APPLYING A GATING SIGNAL TO THE CONTROL MEANS OF A SECOND SWITCHING DEVICE TO ESTABLISH CURRENT FLOW IN THE ARMATURE WINDING OF SAID MOTOR TO PRODUCE AN ARMATURE FIELD ELECTRICALLY DISPLACED 180 DEGREES FROM SAID FIRST ARMATURE FIELD WHEN THAT SAME HALL EFFECT GENERATOR IS UNDER THE COINCIDENT INTER-ACTION OF ITS APPLIED ENERGIZING CURRENT AND ROTOR FLUX OF A SECOND POLARITY.
