Hight quality Hollow shaft DFZ6K magnetic powder Brake 6 N.m for Bag making machine
The magnetic powder clutch is composed of active rotor (input shaft), driver rotor (output shaft) and the 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 the driven rotor is full of alloy powder which has high permeability.
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 . because the magnetic powder clutch is in the state of the 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 sate of the 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 for aslong as the driven rotor of the magnetic powder clutch is fixed
