ABSTRACT:
An induction-motor structure having a synchronous-rotor and an induction-rotor in which inner- and outer-synchronous-rotor poles and a synchronous-rotor-pole connector surround the inner-cylindrical surface of the hollow cylindrical induction rotor, the outer-cylindrical surface of a hollow cylindrical stator core having alternating-current windings and surround the ends of that induction rotor and that core. At least one of the rotor poles includes magnetic field concentrators. A stationary field winding mounted on the end of the stator may be used adjust power factor.
