Multiphase machines in propulsion drives of electric vehicles

Multiphase electric drives have been recently proposed for applications where the highest overall system reliability and power distribution per phase are required. The propulsion drive of an Electric Vehicle (EV) is one of these applications. This paper deals with the use of a five-phase induction machine in the propulsion module of EVs, where the viability of a Predictive Torque Control method (PTC) is analyzed. Simulation results are provided to illustrate the potential of the method, showing fast speed response and low torque ripple.
