A Control Strategy Minimizing PM Loss of Phase-Shifted Dual-Winding PMSM for Aviation Electric Propulsion Application

High-efficiency constitutes a primary objective in the design and operation of permanent magnet synchronous machine (PMSM) in electric propulsion aircraft. The pursuit of high-power-density in PMSM design results in substantial harmonic components within the phase current when the machine is fed by voltage-source inverters, which contribute to additional permanent magnets (PM) loss. In this paper, a control strategy of phase-shifted dual-winding PMSM is proposed, which can effectively suppress PM loss. Analysis is carried out on the principles and outcomes of the control strategy.
