Abstract :
Several speed estimation methods for sensorless induction motor drives have been proposed. Performance of them is not satisfactory at low speed. When the stator resistance value in the speed estimator is incorrect, the estimator does not work satisfactorily. This paper presents a stator resistance estimation method, which works successfully under not only powering condition but also regenerating condition.
