This paper gives a review of sensorless methods developed for AC drives' operation at very low and zero speed. The sensorless drives presented in this paper use reluctance spatial anisotropy to track the mechanical rotor position, allowing the use of vector control. To extract the position information additional test signals in form of active vector pulses or continuous high frequency signals are injected into the machine. This paper also presents a technique which does not make use of… CONTINUE READING
