Servo Driven Wire Tensioner , High Precision Fine Wire Winding Tensioner


The servo wire tension unit uses the wire feeding method for high speed winding control.

by replacing the spring to change its tension value, this product comes with tension feedback

stabilization system that can automatically tension stable equilibrium and with particular stable

tension and easy to adjust.

The feedback system will monitor the tension and make changes to the feeding speed to maintain

the set tension level even during rapid acceleration and to prevent any sudden change in the tension when winding non-round shaped coils.

Poducts Feature:

1. Active wire feeding follow the speed of the winding machine;

2. SF series servo tensioner with online tension measurement display function, the display value is accurate and stable, the display unit is gf;

3. The DC servo motor with high-precision encoder has the following advantages over the servo

tensioner with stepper motor as the wire feeding mechanism:

4. high following accuracy, good tension stability, fast acceleration; low noise;

5. high speed, high torque, large tension range, simple selection;

6. high efficiency, energy saving, low power consumption, minimum operating current, low heat

generation of the motor and drive, no need to dissipate heat;

7. SF***-Ⅰ/ⅡSeries maximum wire speed 12m/s,18m/s,20m/s,tension range 3gf~800gf;

8. SF***-Ⅰis one stage tension setting tensioner;SF***-Ⅱ with two stage tension setting tensioner,

Two-stage tension control is realized by connecting the air supply with 0.5Mpa.

Servo Tension Controller


-Widely used in motor coil,drive coil,transformer coils,relay coils,voice coil,inductance,resistance wire,textiles and other equipment around the system.
