  • Multiple winding design for single or polyphase electric motors with a cage type rotor
    Patent number: 9997983
    Abstract: An electric motor, with a cage type rotor, of single or polyphase design having a multiple winding design in a single stator core. Where the primary winding and secondary winding having a magnetically and electric circuit configured alignment, that is a 0° difference in the respective magnetic alignments or the electric circuitry alignments. Yet completely separate and isolated from one another, electrically and physically. Wherein the prime operative function is configured in a series resonant and a parallel resonant circuit, using capacitors to produce a phase shift in the secondary winding. With the ability to be reconfigured to a secondary operative function, identical to the original winding and in all of its original operative designed functions.
