(Chinese) Topic: 【PCS】 ----------------------------------------------------------------------------------------------- This technical document details a four-dimensional closed-loop analysis method for rotor position estimation failure in dual-motor controllers, aiming to accurately pinpoint the root cause of the fault through multi-layered detection methods. The analysis process progresses from basic to advanced, encompassing macroscopic analysis of external damage, microscopic analysis to explore micron-level damage mechanisms, metallographic analysis to verify component specifications, and operational condition calculations combining electric vehicle dynamic data and mathematical models. Ultimately, the research summarizes the failure causes into 16 core reasons across four dimensions: hardware, software, mechanism, and system, establishing a rigorous diagnostic system from physical evidence to data logic, providing concrete preventative strategies for improving motor control stability.
