New modelling methodology for different PM motors for electric and hybrid vehicles

Abstract

A new modelling methodology is proposed to study PM synchronous motors for electric drives. A nonlinear reluctance network is presented to take saturation effects into account. FEM accuracy is combined to analytical modelling to quicker reach motor performances whatever operating point. A FEM magnetic loss estimation is exploited to obtain efficiency maps and estimate driving cycle consumption. This methodology is used to study different PM rotor configurations.
