Speed Sensorless Vector Control of Asynchronous Motor based on BEMF
Abstract: During the recent years, the research on speed sensorless-control technology of asynchronous motor has become the hotspot. The estimation of the speed of the inductive motor without speed sensor is the core technology issues. This paper adopts the method based on BEMF to estimate the speed, through detection of the current and the voltage of the motor stator to calculate the speed of the asynchronous motor,and validates the feasibility of this approach through simulation.
Keywords: speed sensorless vector control BEMF
