Magnetic Powder Brake 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). #magneticpowderbrake
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. This is to say, the margin can be enlarged as soon as possible when designing.#
Structure and working principle
The magnetic powder clutch is composed of active rotor (input shaft) and Yoke with excitation coil. The three parts are assembled relative concentric and form a system which can rotate relatively. The annular gap between active rotor and driven rotor is full of alloy powder which has high magnetic conductivity.
The magnetic powder will be in the state of loose when the current do not pass the excitation coil. The magnetic powder will be thrown on the inner wall of active rotor. In this case, there will not exist the interaction force between the active and driven rotor. So the magnetic powder clutch is in the state of separation, no torque transmission exits.
The magnetic powder in the working chamber will link in a link state under the action of the magnetic flux generated from the Yoke when the current pass the excitation coil. The magnetic powder clutch can transfer torque relying on the shear force generated from magnetic chain and the friction generated from the magnetic powder and working face. In this case, the magnetic powder clutch is in the state of combination.
When the current is cut off, the magnetic flux will disappear with the disappearance of the magnetizing current, the magnetic powder will be in the state of loose under the action of gravity again, and will be thrown on the inner wall of active rotor under the action of the centrifugal force. In this case, the magnetic powder clutch will be in the state of separation again.
The magnetic powder clutch and brake have the same principle, the magnetic powder brake will form as long as the driven rotor of the magnetic powder clutch is fixed.
