Design and Control of PMSM for In-Wheel Motor Electric Vehicle Application Based on 3D Transient FEA

Permanent Magnet Synchronous Machine (PMSMs) are considered as the promising electromagnetic structure, especially for In-Wheel motor electric and hybrid propulsion applications. The design for a direct-drive wheel motor PMSM require a 3D Finite Element Analysis (FEA) based investigation of the output torque especially when the end winding is considered and in the case of skewed machine, this paper take in to account the study of the PMSM for the proposed application, The cinematic and dynamic model of the EV study for determining the design requirements permit to choose the design that gives the highest torque production capability between two major rotor topologies of the PMSM, the PMSM selected model must be studied with 3D transient FEA, taking in to account the case of linear motion and the case of driving in bend, the PWM control study of the inverter is presented, considering a typical cruising trip of an automobile. Many design parameters are with greet influence on the cogging torque amplitude and on the EV comfort. The obtained in-wheel PMSM model simulator is used for the transient study in the case of the skewing technique application and the effect on the output torque of the PMSM.
