FEM-based modeling and control of 6-phase IPMSM for electric vehicles using JMAG and Matlab Simulink

Abstract

 Research on the modelling and control of an asymmetric six-phase interior permanent magnet synchronous machine (IPMSM) is essential for advancing electric vehicles and high-performance drive systems. This paper presents a modelling and simulation approach for a 100 kW 6-phase IPMSM designed for electric vehicle applications, combining dual dq-axis vector control theory with the Finite Element Method (FEM) using JMAG-Designer to evaluate electromagnetic properties and efficiency. The dual dq model is utilised to analyse flux linkages, inductances, and torque, while FEM addresses nonlinearities, magnetic saturation, harmonics, and asymmetry. The FEM results are integrated into MATLAB/Simulink for validation, enhancing accuracy and ensuring suitability for designing six-phase IPMSMs in electric vehicles, robotics, and intelligent drive systems.
