High Efficiency PMSM with High Slot Fill Factor Coil for Heavy-Duty EV Traction Considering AC Resistance
IEEE Transactions on Energy Conversion(2021)
Abstract
Electric vehicle (EV) systems require a high energy-efficiency traction motor so that the motors for EV traction should achieve high efficiency and power density. Hence, a permanent magnet synchronous motor (PMSM) for EV traction using a maximum slot occupation (MSO) coil has been investigated in this study. By applying the MSO coil, high torque density was achieved, but an additional loss, which ...
