Notes of using powder clutches and brakes

1) Non't overload, meanwhile cool to appropriate tempetature

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 power. (the highest temperature is 80 ¡æ)

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 4500-7500 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.

3) 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.
