Studies on Speed Sensorless of Inductor Motor Based on Saber

Abstract:Speed-sensorless induction motor overcomes various inconveniences and shortcomings of the induction motor with speed-sensor when applied in practice. So this technology has a good application prospect. This paper focuses on the direct calculation method, so a method of calculating the speed of rotor is introduced in it. The model of speed sensorless of inductor motor is built with saber software. Based on this model, the difference between the estimated value with real one is compared, as well as the feasibility of the direct calculation method is verified.
