Permanent magnet brakes and clutches are ideal for light tensioning applications, such as film and fine wires. They require no external power, have a wide range of torque adjustment, have no friction surfaces to wear, and offer chatter-free torque control even at very low speeds.

MPB/MPC Series | POB/PO Series | PMC Series | PHC-R Series

Self-contained magnetic particle clutches and brakes for a wide range of unwind/ rewind applications offer smooth operation at very low speed and electronic control compatibility.

• Torque range from 2 lb.in. through 578 lb.ft.
• Shaft or flange mounting
• Fan cooled in largest sizes.

Accurate torque control with instantaneous engagement!

Warner Electric Precision Tork magnetic particle clutches and brakes are unique because of the wide operating torque range available. Torque to current is almost linear and can be controlled very accurately. The unique features of the magnetic particle clutches and brakes make them ideal for tension control, load simulation, cycling/indexing, and soft starts and stops.

MB Series | MC Series

Precision Tork units provide constant torque independent of slip speed. They offer excellent overload and jam protection for all drive train component and also provide soft starts with zero slip when a preset torque is reached. Precision Tork permanent magnet clutches and brakes do not require maintenance and provide extremely long life.
