A magnetic powder clutch is a special type of electromagnetic clutchwhich does not use friction plates. Instead, it uses a fine powder of magnetically susceptible material (typically stainless steel) to mechanically link an otherwise free wheeling disc attached to one shaft, to a rotor attached to the other shaft.
When a magnetic fieldis applied to the powder, it forms chains connecting the disc and rotor. The strength of the chains depends on the strength of the magnetic field. We use the finest materials available for magnetic components to yield high friction indexes, as well as premium non-asbestos linings to improve response time and extend working life.
