【Abstract】 Addressing the difficulty of traditional HPMSM models in accurately describing motor harmonic characteristics, we propose a digital twin modeling method for HPMSM considering harmonic characteristics. By analyzing the winding function and magnetic field, a parameter model of HPMSM with harmonic characteristics is obtained. An operational state model of HPMSM is then built based on the d-q rotating coordinate system and expressions for various electrical quantities are derived. Our simulation and experimental results show the proposed digital twin simulation platform effectively reveals the spatial harmonic characteristics of HPMSM, providing a fast and efficient general modeling method for the accurate analysis of permanent magnet synchronous motors and their control systems.更多还原
