Automatic web tension controller for magnetic powder clutch/brake

1.Introduction of magnetic powder clutch:

Magnetic powder clutchcan transmit torque based on electromagnetic theory and the use of magnetic powder.It has the characteristics which magnetizing current and transmit torque has a linear relationship,It has advantages of fast response,simple structure,no pollution,no noise,no shock and vibration,energy-saving and so on.It is a versatile,superior performance of automatic control components.Magnetic clutch can also be used to buffer starting,overload protection,speed control and so on.

2.Features of magnetic powder clutch

1)The transmission torque has a linear relationship with the magnetizing current. The size of the torque can get controlled within large range. Under normal circumstance, the magnetizing current has a linear relationship with transitive torque within range of 5%-100% rated torque.

2)The friction part will generate heat inevitably or even destroyed when it keep continuous sliding. But this device has a complete cooling set, it will not generate a lot of heat after long time running and it has a long service life.

3.Application of magnetic powder clutch

It is widely used in printing machinery, paper industry machinery, bag-making machinery, paper-making machinery , wire and cable machinery,coil machinery,wire winding machines,strapping bag machinery, textile machinery, weaving-dimensional machinery, woodworking machinery, steel extruders, CNC lathes, specialized machinery and so on.

4.Advantages of magnetic powder clutch

1) High-precision torque control

2) Superior durability,long life

3) The stability of a fixed superior torque characteristics

4) Continuous operation of the use of sliding

5) Ink sleek,non-shock

6) Suitable for high-frequency operation
