In order to obtain a better dynamic and static characteristics,a detection circuit of the AC servo system was designed. The circuit is composed of current circuit, voltage circuit and position detection circuit. The AC servo control system signals such as DC bus voltage of the motor,the stator phase current of motor and the position of motor rotor are obtained by the circuit. Acquisition circuit of the stator phase current, DC bus voltage of motor and motor rotor position detection was designed. Processing methods of the stator phase current and motor rotor initial position location were given. Experimental analysis was carried out on the circuit. The experimental results show that the 750 rpm step response of experimental motor has good performance and the system has good dynamic response and steady-state accuracy,so the feasibility of detection circuit designed is verified. The study provides a theoretical basis for improving the performance of the AC servo system.
