The control circuit of two-phase servo motor


Posted on Feb 7, 2014

Two-phase servo motor has the field winding and control winding, when the phase difference is 90°, it generates the rotation torque. The potentiometer connected to the motor shaft will get the voltage difference between the corresponding voltage and target value detected by potentiometer, and voltage difference is used as the error voltage, which is used a..
