Computation of a highly saturated permanent magnet synchronous motor for a hybrid electric vehicle

In the framework of the development of a drive system for the implementation in a hybrid electric vehicle, a 45 kW 6-pole permanent magnet synchronous motor (PMSM) is designed. Due to the rotor design with inset permanent magnets the machine parameters are dependant on the operating point due to saturation effects. Numerical computations using the finite element method (FEM) are performed to build up a lumped parameter model of the machine.
