Efficiency Optimization of Surface and De-centered PMSM with Silicon Steel and Amorphous Iron Materials for E-rickshaw

Abstract

Abstract The electric vehicle (EV) industry is developing around the world because of increased air pollution and the rising cost of fuel in traditional vehicles. E-rickshaws are in great demand in nations like India, since three-wheelers are the regular method of transport utilized by citizens. Compared with the induction motor (IM) and switch reluctance motor (SRM), the permanent magnet synchronous motor (PMSM) has the advantages of high power density, high efficiency, and fewer losses. Hence, PMSM is the better choice for E-rickshaw. The efficiency of PMSM is reliant upon the rotor arrangement and materials utilized in the motor. Due to the low cost and simplicity of assembling, silicon steel (SS) is typically utilized in PMSM cores. The intrinsic attributes of SS limit iron loss reduction. The iron loss of amorphous iron (AI) PMSM is less in contrast with SS due to high resistivity, low coercive power, etc. In this paper, efficiency optimization of surface and de-centered PMSM with SS and AI is discussed. The selection of the power rating of PMSM is done based on the E-rickshaw dynamics. The detailed design of PMSM is included. Based on design values, PMSM has virtually evolved from the ANSYS Maxwell stage. The motor parameters are obtained from ANSYS Maxwell, and PMSM is modeled in MATLAB/Simulink.KeywordsE-rickshawEfficiencyPMSMANSYS MaxwellMATLAB/Simulink
