Warner Electric magnetic particle clutches and brakes, from Altra Industrial Motion, used for tension control or torque limiting, are electro-magnetically actuated and consist of input and output members with a cavity between them. Small magnetized metal particles within the cavity eliminate particles as might exist in a friction-design clutch or brake. Products benefit from the clean operation of magnetic particles designs.
