What are the common faults of magnetic particle clutches?

[Myers]

The common faults of magnetic particle clutches are: 1. The tension controller of the magnetic particle clutch brake has no tension. 2. The tension of the magnetic particle clutch brake is intermittent. 3. The magnetic particle clutch brake is stuck. 4. Unstable torque under normal working conditions. Working principle of magnetic particle clutches: The coil stationary magnetic particle clutch and brake are automatic devices that control the input current to change the output torque. When the coil is not energized, the input shaft rotates, and the magnetic particles are pressed against the inner wall of the clamping ring under centrifugal force. There is no contact between the output shaft and the input shaft, resulting in an idling state. When the coil is energized, the magnetic particles form magnetic chains under the action of magnetic lines of force, making the output shaft and input shaft rotate as a rigid body and producing slip when overloaded, resulting in a working state. This achieves the purpose of transmitting torque.
