Sheet Winding Device (Feeder Section) Prevention of Sheet Damage and Sagging by Automatic Adjustment Of Tension

Torque motors can also generate a braking force when rotated in the opposite direction to the motor rotation direction by an external force, etc. If installed on the feeding or unwinding side, the brake characteristics can be used as tension.

Since the torque is always generated in the opposite direction, this prevents the sheet from sagging even when stopped.

Torque motors feature sloping characteristics, with low torque at high speed and high torque at low speed. They move quickly at the beginning of winding when the load is light, and can produce a good amount of torque at low speed near the end of the winding process when the load is larger.

More cost-effective than using tension controllers and torque detectors.

One of the components, the power controller, is used in torque setting. 3 setting methods can be selected: Internal Torque Potentiometer, External Torque Potentiometer, and DC Voltage Control.
