一种具有自适应和直观换相调节的可逆无位置传感器开关磁阻电机驱动器

This paper presents a reversible position sensorless switched reluctance motor (SRM) drive with adaptive and intuitive commutation instant tunings. The narrow voltage pulses are injected into an unenergized phase winding via the PWM channel. The resulted amplitude modulated winding currents are sensed and signal processed to yield the observed Hall signal. No external injection circuit and the mot...
