Sunrise hot selling single shaft powder magnetic clutch
In a magnetic particle clutch, an energized coil applies magnetic flux to magnetic particles in a powder cavity causing them to bind together. The binding of the particles causes the driving (rotor) and driven (armature) components to experience drag which causes torque to be transmitted from one to the other via the particles. The strength of the binding (and accordingly, the deceleration torque generated) can be finely controlled by the varying the amount of current provided to the coil.
