Features of magnetic powder brake

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.
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.

Application of magnetic powder brake

Due to the features of the magnetic powder clutch and brake, they have been widely used in paper making, printing, plastic items, rubber industry, textile industry, printing and dyeing,wire and cable, metallurgy industry and tension control of winding and winding in roll material processing industry.

Description:

Powder brake is used for tension control, overload protector, torque loader, such as printing machine, paper making machine, re-reeling machine, wire drawing machine, metal calender, film processor, textile machine etc.; or the loading device when doing loading experiments, such as motor, engine, hydraulic gear reducer.

Magnetic brake is based on electromagnetic theory and the use of magnetic torque transmission. Its exciting current and transmission of torque with a linear relationship between the basic features. Has nothing to do with the slip case to pass a certain torque, with fast response, simple structure, no pollution, no noise, no shock and vibration energy-saving advantages. It is multi-purpose, superior performance, the automatic control devices. It is now widely used in various machinery for the purpose of braking, power test load, unreeling tension control and so on.

About life of magnetic powder brake
The use of magnetic powder clutch/brake life lies in the life of the magnetic powder.In general, magnetic powder in the condition of not overloaded, its service life is 4500~7500 hours;But in some condition it can prolong service life many times, such as: reduce the magnetic powder clutch/brake torque, relative sliding speed and slip power to the rating of 50% 70%.That is to say, when the design, allowance enlarge some as much as possible.

About the torque of magnetic powder brake
Magnetic powder clutch/brake factory after use, the magnetic powder in the early stages of using break-in happens, torque will be slightly down, can be adjusted by electric current to compensate.  

Notes

1. Don’t overload, meanwhile cool to appropriate temperature

The value of the torque/rotational speed/slip power should be less than the rated value. The cooling mode(natural cooling/forced air cooling/water cooling) should depend on the maximum slip power when it works and the cooling air should pass the water and oil filter. The temperature detector and the alarm should be installed to prevent high temperature which can affect the service life of the magnetic powder.(the highest temperature is 80 degree)

2. Concerning the torque

After the high qualiity magnetic powder clutch and electromagnetic power brake working, the magnetic powder will be in grinding at the beginning which leads to the torque decreasing slightly, but the gap can be compensated through adjustment the current.

3. Concerning the service life

The life of the magnetic powder clutch and magnetic brake rely on the life of the magnetic powder. Generally speaking, its service life is 4500-7500hours in the state of non overloaded; but its service life can extend several times in some cases, such as: the working torque of the magnetic powder clutch/brake,relative slip rotational speed and slip power can be reduced to 50%-70% of the rated value. This is to say, the margin can be enlarged as soon as possible when designing.
