非理想不对称反电动势无传感器无刷直流电机换相误差闭环补偿策略

This article focuses on the sensorless commutation strategy of brushless DC (BLDC) motor with three-phase nonideal asymmetric back-EMFs (NAEMFs). To improve the torque performance and reduce power consumption, this article addresses two key issues: pointing out the accurate commutation positions of the BLDC motor with NAEMFs and proposing a novel closed-loop commutation error compensation strategy...
