Servo Motor Torque Control

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.

How it Works

FUTEK's TFF500 Reaction Torque Sensor is mounted between a CGI Prime 017PLX Planetary Angle Gearhead and the gearhead’s mounting location.
As the servo motor runs, the torque produced and transmitted through the NEMA 17 gearhead is measured by the TFF500.
The IAA analog amplifier amplifies the TFF500 signal for input into a PLC for closed loop control of torque.
