The KBTC controls are designed to control a motor's torque, by controlling motor current. Unlike a traditional KBIC, which controls voltage and limits current, the main potentiometer of the KBTC sets current. Also, motor current will not vary over the speed range. If the load is less than the current setpoint, the KBTC goes to maximum voltage. Typical applications include winders, and tension rolls in web processing lines such as found in paper, textile, blown film and coating industries.
