A Flexible Model of PMSM to Design High Density Traction Systems for Electric Vehicles

In this paper a PMSM model is proposed as a flexible and accurate tool for machine designers to conveniently evaluate the performances of a new PMSM design or a specific modification on an existing design base on the stator and rotor geometries. A step-by-step procedure is discussed, and informed assumptions are proposed to keep the model adaptable to different geometries. A reference IPM motor is used as an example of an application of the model. The model results are compared with FEA-based simulation and experimental validation.
