Servo Motor Characteristic

The principle of AC servo motor and AC induction motors of the same. Two phase-space displacement of 90 ° in the stator electrical angle of the excitation winding Wf and WcoWf by constant exchange of control winding voltage, applied to the Wc AC voltage or phase change, achieve the purpose of control motor operation. AC servo motor good running stability, controllability, fast response, high sensitivity, as well as mechanical properties and characteristics of non-linear index strictly (respectively less than 10%~15% and less than 15%~25%) and so on
