Brushless direct current motor

Claim 1

AN ELECTRICAL MOTOR COMPRISING: (A) FIELD COILS SUITABLY MOUNTED FOR GENERATING MAGNETIC FIELDS IN SELECTED AREAS; (B) A PERMANENTLY MAGNETIZED ROTOR SUITABLY MOUNTED FOR ROTATION WITHIN SAID AREAS; (C) A SOURCE OF ELECTRIC POWER, INCLUDING SWITCHING MEANS, COUPLED WITH SAID FIELD COILS TO SELECTIVELY ENERGIZE SAID FIELD COILS WHEN SAID SWITCHING MEANS IS CONDUCTIVE; (D) A STRUCTURE MADE OF FERROMAGNETIC MATERIAL DEFINING A PLURALITY OF OPEN FLUX PATH CIRCUITS HAVING A FIRST WINDING COUPLED WITH SAID SWITCHING MEANS AND MAGNETICALLY COUPLED WITH A SELECTED PORTION OF SAID STRUCTURE FOR CONTROLLING THE CONDUCTIVITY OF SAID SWITCHING MEANS IN A RELATIONSHIP TO THE POLARITY OF A CURRENT INDUCED IN SAID WINDING; (E) A SECOND WINDING, COUPLED WITH SAID SWITCHING MEANS AND POWERED BY SAID SOURCE OF ELECTRIC POWER SO THAT SAID SECOND WINDING IS ENERGIZED WHEN SAID SWITCHING MEANS IS CONDUCTIVE, MAGNETICALLY COUPLED WITH A SELECTED PORTION OF SAID STRUCTURE TO INDUCE SAID CURRENT IN SAID FIRST WINDING; (F) AND A SECOND STRUCTURE, SUITABLY MOUNTED FOR ROTATION WITH SAID ROTOR, HAVING SECTIONS OF FERROMAGNETIC MATERIAL POSITIONED ON SELECTED AREAS OF SAID SECOND STRUCTURE TO SELECTIVELY CLOSE SAID FLUX PATH CIRCUITS IN A RELATIONSHIP TO THE POSITION OF SAID ROTOR FOR CONTROLLING THE POLARITY OF SAID CURRENT INDUCED IN SAID FIRST WINDING BY CONTROLLING THE PATH OF SAID MAGNETIC FLUX; (G) SAID SECOND STRUCTURE HAVING SELECTED POSITIONS THAT DIRECT SAID MAGNETIC FIELD TO INDUCE SAID CURRENT IN SAID FIRST WINDING TO BE OF A SELECTED POLARITY THAT COMPLEMENTS THE CONDUCTIVITY OF SAID SWITCHING MEANS AND CAUSES SAID SWITCHING MEANS TO SUSTAIN A STATE OF OSCILLATIONS IN SAID SECOND WINDING AND HAVING OTHER PORTIONS THAT REVERSE SAID SELECTED POLARITY AND PREVENT SAID SWITCHING MEANS FROM BEING CONDUCTIVE.
