This paper proposes an optimal vector control strategy to minimize copper losses and to improve the power factor and the efficiency of a multiphase induction machine drive system. Indeed, the proposed approach aims to minimize the magnetizing energy by adjusting the magnetic state of the motor regarding the drive’s operating point. As a result, the current circulating through the motor windings can be reduced, which leads to copper losses reduction. Hence, an improvement in the machine’s power factor and efficiency is obtained. Simulation and experimental results are carried out on a drive system based on a dual star induction machine to validate the proposed control approach.
