Due to the limited available space and the high demands in power density and overall efficiency, the permanent magnet synchronous machine (PMSM) is the mainly applied machine type in parallel hybrid electric vehicles (HEV), in many electric vehicles (EV) this machine is used as well. In this work several permanent-magnet excited rotor types are studied regarding their applicability in EVs and HEVs, and are compared in terms of among others: their maximum torque and power, power density, their efficiency map, field-weakening capability, overload capacity and torque ripple.
