Torque Control of Servo Motor | Servo Motor Torque Control | FUTEK

Application Summary

Automated systems in a variety of different industries rely on servo
motors to monitor linear and rotational motion. Frictional loss and
motor speed change necessitate the inclusion of a closed loop control
system. To accomplish this, place a reaction torque sensor between the
servo gearbox and its mounting location to measure the generated torque.

Products in Use

FUTEK's TFF500 Reaction Torque Sensor with Thru Hole Center paired with an IAA Series Analog Amplifier for torque control of servo motor.

How it Works
  1. FUTEK's TFF500 Reaction Torque Sensor is mounted between a CGI Prime  017PLX Planetary Angle Gearhead and the gearhead’s mounting location.

  2. As the servo motor runs, the torque produced and transmitted through the NEMA 17 gearhead is measured by the TFF500 (servo motor torque feedback).

  3. The IAA analog amplifier amplifies the TFF500 signal for input into a PLC for closed loop control of torque.

  4. Tmotor = Torque applied by the motor + gearbox (red arrow);
    Treaction = Reaction torque measured by the FUTEK Reaction Torque Sensors (blue Arrow) that keeps the motor stator/body from spinning ;
    Treaction = -Tmotor.
