摘要
讨论了一种新型交流调速系统———无速度传感器的速度闭环控制系统利用测量感应电动机的定子电压、电流的值,通过运算得出定子磁通ψ1和转矩Te,然后计算出转差ω2。
A new type of AC variable speed system——the speed feedback system without speed transducer is discussed.Through the measurement of stator voltage and stator current and the calculation of the measured values,the stator flux ψ 1 and the torque T e are obtained.Then the slip frequency ω 2 is obtained and fed back instead of speed ω r.
