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

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 (servo motor torque feedback).

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

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.
