Abstract：Asynchronous motor is widely used in the field of frequency control of motor speed, because of its simple manufacture, high performance, small moment of inertia, high reliability advantages, and occupies a more and more important position in the national life. Based on the main motor control chip IRMCF341, a technique that makes the current sampling and reconstruction of the DC bus realized was analyzed in this paper. The sensorless control algorithm of asynchronous motor was completed, using the method of back electromotive force to estimate the motor rotor speed and position. Finally the debugging experimental of the whole control system was done, and the experimental results verify the correctness and feasibility of the sensorless vector control algorithm.
