The winding drive is commonly used in the technological process of textile material's dyeing and flatting. During drive, the tensile force in material is usually in fluctuation, affecting the product quality and production efficiency. On account of this phenomenon, mechanical analysis of the winding drive is conducted and the technique of vector control frequency conversion is adopted for its control. A practicable empirical formula is put forward and a practical example is carried out to verify its feasibility. The effect of the control way is proven to be satisfactory. It is concluded that the tensile force control by use of the technique of vector control frequency conversion is of practical value and can be spread to designing of the similar kinds of drives.
