    11KW AC Servo-Motor Details

    Tips: Difference between a servo spindle motor and a torque motor.

    • Servo spindle motor: It can make the control speed and position accuracy very accurate. Servo spindle motor can convert the voltage signal into torque and speed to drive the control object. Speed of the servo spindle motor rotor is controlled by the input signal and can react quickly. In the automation control system, servo spindle motor is used as an actuator. It has the characteristics of small electromechanical time constant, high linearity, and starting voltage.
    • Torque motor: It is a special motor with a large number of poles, which can continue to run at low speeds or even when the motor is locked (that is, the rotor cannot rotate) without causing damage to the motor. In this working mode, the motor can provide a stable torque to the load.
