Ordinary torque motors approximate torque control through current adjustment but suffer from poor linearity, slow response speeds, and unstable low-speed performance, especially with significant diameter changes that cause substantial tension fluctuations. Servo motors provide superior performance through: Precise Control with true closed-loop torque control and consistent output; Extremely Fast Response with millisecond-level reaction to tension changes; Excellent Low-Speed Performance ensuring smooth torque at minimal winding speeds; and High Intelligence for seamless PLC integration with complex diameter calculation and taper control capabilities.

Stretching tension primarily influences the product's final strength and elongation characteristics. Optimal settings require experimentation within the equipment's operational range (0.5-5N) based on raw material properties, product specifications, and target performance metrics. For winding tension, initial settings must ensure neat roll formation without product damage. Starting tension on empty cores should be sufficient to prevent slippage but not excessive to avoid strap crushing. As roll diameter increases, applying taper tension to gradually reduce tension (typically linearly from full tension down to 70%) effectively prevents inner layer deformation from excessive pressure. We provide initial process parameter recommendations and assist customers with optimization during commissioning.
