The Magneclutch Advantage
The Magneclutch provides complete control because magnetic particle action makes torque output directly proportional to coil current, independent of slip speed. The Magneclutch makes equipment more controllable and stable, longer lasting and easier to maintain.
Automatic Tension Control
The infinitely smooth Magneclutch has no starting peaks. It allows precise winding and unwinding of material under constant tension, taper tension or constant torque, using all types of digital or analog closed loop systems to automatically maintain control tension.
Simplified Material Handling
A Magneclutch simplifies material handling. Its soft starting through infinitely smooth torque control eliminates load shifting, swinging, banging and material damage.
Precise Acceleration
Magneclutch simplifies acceleration of large inertia loads. Acceleration times and forces can be precisely limited with excellent repeatability.
Operational Stability
Since its clutching action is entirely magnetic and without friction-dependent mechanisms, the Magneclutch retains operational stability throughout its operating range over a practically unlimited lifetime.
Quiet
Unlike conventional clutches, the noiseless Magneclutch is welcome in quiet areas like offices, labs and medical facilities. With no sliding or slapping parts, the Magneclutch is a valuable tool in the machine designer's portfolio.
Controlled Repeatability
A Magneclutch is ideal for applications with extreme cycle demands. It provides millions of exact stable cycles under complete control with the smoothest starts and the most gentle stops possible for machinery.
Lowest Cost
Equipment controlled by a Magneclutch is protected from vibration, chatter and overload, extending its life and reducing its cost of ownership. Two-wire control simplifies installations for direct and easy to maintain remote control. Magneclutch installation time and expense is minimal because bearings and shaft attachments for mounting are included. When all installation, downtime, maintenance, parts, replacement and servicing of other clutch types is considered, the Magneclutch is the lowest cost clutch available.
Best for Test
When products must be observed under dynamic conditions, a Magneclutch is the perfect interface for test equipment. A Magneclutch handles the precise cycles required in production line testing with ease and reliability. It allows precision drive components to be tested with programmed speed-torque functions, and can provide versatile, flexible loads for all types of engineering tests under almost any environmental condition. The linear, two-wire control of every Magneclutch allows automatic control of any test function.
Remote Control
Remote operation is simple with two-wire control and currents usually less than 500ma. The low power transfer allows control placement at a convenient operating point.
Friction clutches and brakes have long been used to regulate drive speeds and loads in most industrial applications. However, Magneclutches® and Magnebrakes® control tension, torque and acceleration with no wearing parts. There are no gears to grab and no pads to wear out.
The magnetic particle clutch was developed by the Vickers Corporation in 1948. It was first used as a speed control on generators for the Navy. Sperry later refined the control and its applications. Now, Magne continues the development of these magnetic particle products by improving product design, expanding applications and providing outstanding service.
The Magneclutch® consists of only two moving parts, the inner rotating member, called the rotor, and the outer rotating member, called the drive cylinder. These rotating members do not touch. Each is cantilevered on two separate bearing sets. When the coil is energized, a magnetic medium forms chains between the rotor and drive cylinder and transmits torque. The transmitted torque varies with the magnetic field's strength. Since its clutching action is entirely magnetic - and without friction dependent mechanisms - the Magneclutch® retains operational stability throughout its operating range over a practically unlimited lifetime.
