1. A rotary induction machine comprising:

  • a plurality of axially spaced rotors;

    a plurality of axially spaced stators interstitially disposed with said rotors;

    a plurality of magnetically isolated magnetic teeth on each of said rotors and said stators, the plurality of teeth on each rotor being different in number from the plurality of teeth on each stator;

    return means including magnetic material for establishing a low reluctance azimuthal flux path;

    a plurality of conductor paths surrounding said teeth on each said rotor; and

    a plurality of electrical windings on each stator, each winding surrounding a different group of magnetic teeth for inducing a magnetic flux axially in a path in series through corresponding groups of teeth on successive rotor and stator disks and returning azimuthally through said return means.
