Magnetic Powder Brake for Unwinder

 Introduction

Electro Magnetic powder brake can transmit torque based on electromagnetic theory and the use of magnetic powder inside the brake. it is a connector that transmits the active side torque to the passive side. It can freely combine, cut off and brake according shearing force generated between the magnetic powder chains are transmitted. The torque transmitted is linear, 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 brake an also be used to buffer starting, overload protection, speed control and so on.

 Features

• The transmission torque is linear controlled by the magnetizing current. The torque can get controlled within large range of 5%-100% rated torque.

• 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.

• Under control of automatic tension controller, the torque of the powder brake can controlled very precisely, will eliminate any human mistake.

 Application

    Powder brake 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.

 Advantages

1) High-precision torque control

2) Superior durability, long life

3) The stability of fixed superior torque characteristics

4) Continuous operation of the use of sliding

5) Ink sleek, non-shock

6) Suitable for high-frequency operation

 Cooling treatment

There is a natural cooling fan inside the brake, cooling the temperature and make the brake stable.
