S1 Series AC Servo Motors

An AC servo motor operates using a closed-loop control system. In this setup, the motor receives signals from a servo controller, which determines the required motion parameters based on input commands. A feedback device continuously monitors the motor's performance, sending data back to the controller. This allows for instant corrections in speed or position, ensuring high accuracy.

1、Controller sends input signals for speed or position.

2、Drive unit converts these signals into electrical power for the motor.

3、Rotor movement occurs as the stator generates a rotating magnetic field.

4、Feedback system (encoder/resolver) measures performance.

5、Controller adjusts output to match the desired setpoint.
