Hi nadeem, In addition to a wide range of applications where drives are used to control the speed (variable-speed drives), there are also numerous cases where it is necessary to control the drive torque. Typical applications for closed-loop torque controls are as follows Axial winder: Axial winders are used to wind and unwind material webs, cables, wires etc. Constant speed is not decisive – but instead constant tension over the complete winding range. The tension is controlled using a dancer roll, with tension measuring transducer or indirectly using the motor torque.
