A system for speed-sensorless control of an induction machine includes a flux regulator & torque current calculator for operating the machine in a heavily saturated state to produce a saturation induced saliency; a saliency tracker for tracking an angle of the saturation-induced saliency; a signal injector for injecting an AC signal aligned with a saliency axis; voltage and current determiners for determining stator voltages and currents; and a rotor flux calculator for using the saturation-induced saliency angle, the determined stator voltages, and the determined stator currents to determine a magnitude and a location of a rotor flux vector. The flux regulator & torque current calculator is adapted to use the rotor flux vector to control the induction machine.
