    Abstract: A drive system for providing ac drive power to an induction machine with asymmetrical rotor resistance and for sensorless rotor tracking of the induction machine includes: a signal injector for determining a stator command signal in a reference frame which is aligned with either an estimated rotor reference frame; a signal determiner for determining a feedback stator signal of the induction machine in a stator reference frame; and a rotor position and velocity tracker for using the feedback stator signal to estimate a rotor velocity and position by transforming the feedback stator signal into an orthogonal axis feedback stator signal in the estimated rotor reference frame, isolating a component of the orthogonal axis feedback stator signal which is in-phase with the injected stator command signals, filtering the isolated component to isolate an error term, and generating a position estimate by driving the isolated error term towards zero. In several related embodiments a flux axis stator command signal is injected into the drive system and flux axis and torque axis stator feedback signals are then used for rotor position and velocity tracking.

    Abstract: This document discusses, among other things, a stator with transposition between the windings or coils. The coils are free from transposition to increase the fill factor of the stator slots. The transposition at the end connections between an inner coil and an outer coil provide transposition to reduce circulating current loss. The increased fill factor reduces further current losses. Such a stator is used in a dual rotor, permanent magnet machine, for example, in a compressor pump, wind turbine gearbox, wind turbine rotor.
