    This paper presents an advanced modeling approach for a surface-mounted permanent magnet synchronous motor (SPMSM) drive system that incorporates the nonlinear effects of both the motor and the inverter.The motor model integrates magnetic saturation and spatial harmonics to enhance accuracy, while the inverter model accounts for semiconductor voltage drops and dead time effects.The proposed model was validated through simulations utilizing JMAG-RT and MATLAB-Simulink, as well as experimental verification using a dynamometer. The results demonstrate that output distortions caused by the nonlinearities of the motor and inverter vary significantly depending on the operating points, highlighting the necessity of comprehensively considering these nonlinear effects for accurate analysis of output waveform quality. This study provides a reliable and precise tool for drive performance evaluation during the early design stages.
