Transformer-like induction motor having various coupling ratios between windings

Claim 1

AN A.C. MOTOR COMPRISING A STATOR HAVING A STATOR WINDING THEREON AND A ROTOR HAVING A ROTOR WINDING THEREON, ONE OF SAID WINDINGS HAVING AT LEAST ONE MAIN WINDING PORTION AND AT LEAST ONE AUXILIARY WINDING PORTION POSITIONED AT A SELECTED SPACE ANGLE RELATIVE TO SAID MAIN WINDING PORTION, SAID MAIN WINDING PORTION CONSISTING OF AT LEAST TWO PRIMARY WINDING SECTIONS AND AT LEAST ONE SECONDARY WINDING SECTION, SAID PRIMARY WINDING SECTIONS ENERGIZED BY AN A.C. SOURCE, AND ONE OF SAID PRIMARY WINDING SECTIONS BE MUTUALLY INDUCTIVELY COUPLED IN CLOSER RELATIONSHIP THAN THE OUTER TO SAID SECONDARY WINDING SECTION, MEANS CONNECTING ONE TERMINAL END OF SAID SECONDARY WINDING SECTION TO ONE SELECTED TERMINAL END OF EACH OF TWO OF SAID AT LEAST TWO PRIMARY WINDING SECTIONS, MEANS CONNECTING SAID AUXILIARY WINDING PORTION TO SELECTED POINTS ON SAID AT LEAST ONE MAIN WINDING PORTION, SAID MEANS CONNECTING SAID AUXILIARY WINDING PORTION SO AS TO BE ENERGIZED BY A.C. IN PART AT LEAST FROM AT LEAST A PART OF SAID SECONDARY WINDING SECTION, MEANS PROVIDING AT LEAST ONE PHASE SHIFTING MEANS, INCLUDING LEAKAGE REACTANCE MEANS, TO CHANGE THE PHASE OF THE CURRENT IN THE SAID AUXILIARY WINDING PORTION RELATIVE TO THE CURRENT IN THE SAID PRIMARY WINDING SECTIONS OF SAID MAIN WINDING PORTION, AT LEAST DURING THE STARTING OF SAID MOTOR.
