Attention for using magnetic powder brake:

1 Install it with correct mounting method (make high-speed rotation side as the input side) to use the magnetic powder clutch. If the mechanical structure of output and input shafts have to be installation reversely, make sure to use the under 1000R/MIN. If the output shaft and input shaft be installed reversely, which will make the machine idle for a long time, the magnetic powder clutch will greatly shorten the life by mixing magnetic powder.

2 Note the moisture. If the magnetic is damp, then performance will become unstable, so be careful do not to let the oil or water get into the housing. Especially when installed in the gear box, oil penetrated the internal branch of the housing through the shaft, so please seal it with film completely.

3 Note the surface temperature. Caused by continuous operation, the maximum temperature of the surface is below 90 degree when running more, than the value and durability will be greatly reduced. Make sure to limit the temperature will not above90 degree, make sure to keep the use of sliding within allowed work range.

General introduction:


The magnetic powder clutch is composed of active rotor (input shaft),driven rotor(output 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 magnetic alloy powder which has high magnetic conductivity.
The magnetic powder will be in the state of loose situation 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 situation, the magnetic powder clutch is in the combination state.
When the current is cut off, the magnetic flux will disappear along 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 driven rotor of the magnetic powder clutch is fixed.
