Magnetic Particle Clutches and Brakes
MPB/MPC Series | POB/PO Series | PMC Series | PHC-R Series
These power applied, self-contained, electromagnetic particle clutches and brakes are ideal for a wide range of unwind/rewind applications and operate smoothly at very low speeds. Our Magnetic Particle Clutches and Brakes are extremely versatile; offering either shaft or flange mounting, and an extremely wide torque range from 2 lb.in. through 578 lb.ft., with fan cooling available in larger sizes. The torque to current is almost linear and can very quickly and accurately provide perfectly controlled, jerk-free engagement at a speed that it entirely customer-controlled. Magnetic Particle Brakes are compact and offer a high torque to size ratio and low consumption of electric power. They also have no wearing parts because there are no friction surfaces to grab or wear and they’re not affected by changes in atmospheric or other environmental conditions. This brake and clutch series is ideal for applications that require tension control, load simulation, cycling/indexing, and soft starts and stops and has off the shelf availability in industry standard sizes.
Features
- The torque is independent of slip speed, depending only on circuit current, and is infinitely variable from 0 (disengaged) to rated torque
- Response of the particles to the field is virtually instantaneous, providing perfectly controlled, jerk-free engagement
- The frequency and torque of the engagement/disengagement sequence is limited only by the capabilities of the control circuitry
- There are no friction surfaces to grab or wear, and the units are not affected by changes in atmospheric or other environmental conditions
- High torque to size ratio and low consumption of electric power
- Convenient bolt circle for easy mounting. Mounting brackets available for all sizes
- Off the shelf availability that is interchangeable with industry standard sizes.
