Open-End Winding Five-Phase Induction Motors (OEW-FPIM) can offer high degree of faults tolerance, reduced common-mode voltage and high torque density. These motors are placed in varying environments and conditions that ultimately reduces the motor efficiency and later leads to failure. This paper proposes a fault-tolerant sensorless sliding mode control based on a parameters estimation (stator resistance, stator inductance and mutual inductance between the stator phases and the rotor phases) of OEW-FPIM with the ability to run the system disturbance-free before and after a short circuit fault between turns. The proposed estimation scheme is intended to improve the system performance even in the fault condition. In addition, a sliding mode observer (SMO) is used to estimate the rotor speed. The simulation results of the proposed sensorless control under a short circuit fault between turns, wherein we demonstrate the effectiveness of the proposed strategy.
