This paper introduces a design of a sensorless control of a five-phase permanent magnet synchronous motor drive working at low and zero speeds with low current distortion. The rotor position is obtained through tracking the saturation saliency. The saliency position is tracked through measuring the dynamic current response of the motor line currents due to the insulated-gate bipolar transistor switching actions. It uses the fundamental pulse width modulation (PWM) waveform obtained using the multi-phase space vector pulse width modulation only. The saliency tracking algorithm used in this paper does not only improve the quality of the estimated position signals but also guarantees a minimum current distortion. It reduces the modifications introduced on the PWM waveform. Simulation results are provided to verify the effectiveness of the proposed design over a wide speed range under different load conditions
