Permanent magnet (PM) synchronous machines (PMSMs) have been widely used in electric vehicle (EV) drives because of their high torque/power density and high efficiency. To meet the requirement of high-speed operation for EV applications, a common control method of the negative d-axis current is employed to reduce the air-gap magnetic field, which may result in irreversible demagnetization risk of the PMs. To achieve a constant-power operation capability in high-speed conditions, a new reverse salient consequent-pole PM (RSCPPM) machine is proposed and developed with consequent-pole rotor design, which is characterized by multiple rotor flux barriers and hence resulting a higher d-axis inductance than q-axis inductance. Subsequently, the influence of key parameters, including the split ratio, PM width, rotor flux barrier width, and different load currents, on the flux weakening coefficient of the proposed RSCPPM machines are investigated by the finite element (FE) method. Lastly, experiment results on the RSCPPM prototype were conducted, and the tested results matched well with the FE simulations.
