Research on power distribution of dual three-phase permanent magnet synchronous motor for electric vehicles

Abstract

This study investigates the power distribution characteristics of a dual three-phase Permanent Magnet Synchronous Motor (PMSM) for Electric Vehicles (EVs). The dual three-phase PMSM configuration offers several advantages, including higher power density, greater fault tolerance, and better torque performance. In this study, the power distribution strategy for a dual motor system is investigated through mathematical modeling and simulation analysis using MATLAB Simulink, and various operating conditions are considered. In addition, the decoupling effect is also explored based on Vector Space Decomposition (VSD). Overall, the study of power distribution in dual three-phase PMSMs for electric vehicles may provide useful insights for improving motor performance and efficiency. It contributes to the future development of dual three-phase PMSMs and their application in electric vehicles, adding more efficient, sustainable and reliable transportation options.
