Powder Clutch Structure:
The magnetic powder clutch is composed of active rotor(input shaft), driven rotor (output shaft) and Yoke with excitation coil. The three parts are resembled against the concentric part and form a system which can rotate relatively. The annular gap between active rotor and driven rotors is full of alloy powder which has high permeability.
Powder Clutch 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.
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 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 4500-7500hours 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.
3.Concerning the torque
After the magnetic powder clutch and 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..
