Force Control Industries presents the POSIDYNE® size #1.5 clutch/brake which provides precise repeatability and control for drives up to 5HP. They feature Oil Shear Technology that allows rapid and precise stopping, starting, reversing, speed changes and positioning – all without adjustment and virtually zero maintenance. These unique motion control devices allow higher cycle rates (up to 300 cycles per minute), to increase production rates with lower downtime. This compact, lightweight clutch/brake includes unique mounting features such as double C-Face arrangements for fast and easy installation, and a split-clamped quill to eliminate keyway damage common with competitive clutch/brake models. A multiple disc design produces high torque from a small package, boosting accuracy, cycle rates, and lifetime (20,000,000 – 40,000,000 cycles), making it ideal for applications with frequent start/stop cycles, such as conveyers, packaging machines, food processing applications, extruder cut-offs, and more.

Faster production rates coupled with significantly longer service life than traditional (dry) clutch/brakes (typically 5 to 10 times longer life) yields increased uptime, productivity and ROI, especially for 24/7 operations. No adjustment, virtually no maintenance, multi-year service life, minimal parts inventory, reduced parts and replacement ordering cost, adds up to higher production at less cost.

Small Unit, Big Impact—Innovative Design 

The POSIDYNE #1.5 features an innovative Split-Clamped Quill feature, which reduces shaft and keyway damage to the motor shaft associated with competitive clutch/brakes. The split quill collar tightens the quill 360° around the shaft and key for superior connection. For mounting to smaller frames, the #1.5 uses a unique hidden mounting spools arrangement to tighten the motor against the clutch/brake.

Convenient options such as foot mounting kits, manifold mounted valves and optical encoders are available to fit most applications. The totally enclosed POSIDYNE clutch/brake is impervious to dust, chips, chemicals, coolants, caustic wash down, weather, and more, making them ideal for hostile environments, and severe or hazardous duty.

All POSIDYNE clutch/brakes are designed with low inertia cycling components. This makes the POSIDYNE #1.5 clutch/brake even more efficient, requiring less motor horsepower to accelerate the load, and less torque to stop the load—which adds up to significant energy savings in 24/7 manufacturing demands.

A simple actuation system allows torque in the clutch and brake to be precisely controlled. Adjustment for rapid or soft starts and stops is easily accomplished. Manifold mounted control valves reduce response times by eliminating hoses and fittings. By reducing the high starting inrush currents and the associated power factor imbalance, these unique clutch/brakes can also reduce energy costs.

The POSIDYNE clutch/brake can be actuated either by air or hydraulic pressure for use in plant or outdoor applications. The hydraulic actuation package includes a hydraulic pump, solenoid valve, regulators, and a filter. A heat exchanger can be added for additional cooling. The POSIDYNE #1.5 is inherently explosion-proof with the addition of an explosion-proof solenoid valve. And the valve assembly can also be remotely mounted in an explosion-proof cabinet.

Oil Shear Technology Makes the Difference

Oil Shear Technology is the reason that brakes by Force Control last up to 10 times longer than standard dry friction brakes and do not need maintenance, adjustment, or disc replacement. Oil Shear Technology is the function of a boundary layer of transmission fluid in shear between the friction discs and drive plates. As the parts come together, the fluid under shear will transmit torque between the two parts, as well as absorb heat. This eliminates direct contact of the friction discs and drive plates during high-speed slip. Heat from the friction surface is dissipated as the fluid circulates to the housing.

Heat dissipation is a major component when selecting a clutch/brake. The POSIDYNE clutch/brake basic unit dissipates heat through the housing by flowing the fluid from the friction surface to the housing. Additional heat can be dissipated by adding an integral fan, water cooling, and even pulling the fluid out of the unit for additional heat exchanger cooling and filtration. These cooling options allow the same compact size POSIDYNE clutch/brake to be used on high inertia loads, or in extremely high or low temperatures. Re-circulating the fluid dissipates the heat of engagement, which is a common cause of downtime with other clutch/brake assemblies.
