Wholesale price powder brake controller press for coating machine

Features: 

The magnetizing current has a linear relationship with torque 

As is shown in chart3,the transmission torque has a linear relationship with the magnetizing current.The size of the torque can get controlled within larger range.Under normal circumstance,the magnetizing current has a linear relationship with transitive torque within range of 5%-100% rated torque.

Stable slip torque

The slip rotational speed between driven rotor and active rotor do not affect the transitive torque when the magnetizing current retain unchanged,as shown in chart 4.That is to say,the static friction torque and the dynamic friction torque have no difference.Therefore,the torque can retain constant stably.The features are applied to tension control,users can control the tension of the roll material effectively as long as adjust the magnetizing current accurately.

Prevention heat phenomenon from slip

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.

Main application

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 unwinding in roll material processing industry.A complete set of schematic of tension control system is as follows.

Moreover,the magnetic powder clutch can be also used in buffering start,overload protection,speed adjustment;the magnetic powder brake can also be used in test loading and braking of the transmission machinery.

Notes:

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 filter the water and oil.The temperature detector and the alarm device should be installed to prevent high temperature which can affect the service life of the magnetic powder.(the highest temperature is 80℃)

Concerning the service life

The life of the magnetic powder clutch and brake rely on the life of the magnetic powder.Generally speaking,its service life is 4500-7500 hours 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.That is to say,the margin can be enlarged as soon as possible when designing.

Concerning the torque

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