The CLPC Closed Loop Position Control is used to improve positioning accuracy on Posidyne Clutch/Brakes and Posistop Motor Brakes beyond what can be achieved with just a limit switch, or a PLC control system. The CLPC is a closed loop positioning control, which looks at the stopping position and continually makes adjustments if any “Stopped Position” errors begin to occur. This is particularly important during a cold start to hot run, and if changes that occur on the line such as changes in load, speed or temperature.

The Foot Mounted Posistop Brake is similar in design to the Posidyne Clutch/Brake incorporating many of the same features including multiple friction surfaces, lubrication and cooling by recirculating fluid. Six sizes are available with torque ratings up to 1800 Lb.Ft. There are three control logics to select from:
S = Air Set Brake / Spring Release
A = Medium Spring Set Brake / Air Release
B = Heavy Spring Set Brake / Air Release

The spring set units are preset at the factory and are not adjustable. The air set units are adjustable over the full range.

MagnaShear^® Motor Brakes combine oil shear durability with electric actuation, simple control logic and spring-set load holding. Easy to install, economical to operate, MagnaShear^® motor brakes run on 115 VAC, 50 or 60 Hz.. An optional Step Down Transformer is available for other voltages. They fit a wide range of motors, including NEMA U-frame, and T-frame motors.

MagnaShear^® Oil Shear Brakes are designed to dissipate the heat buildup that destroy conventional braking devices.

Force Control’s family of Oil Shear Clutch and Brake Products is most often actuated by a Pneumatic Control Valve. Torque control of the units is accomplished by adjusting the actuation pressure. To aid the designer in the selection specification of the correct control circuit the charts below have been provided. During the selection process of the Posidyne or Posistop a particular logic type was decided upon. Based on the logic type of your unit find the correct control valve model number indicated in the appropriate chart.

Today's Posidyne^® is a modern motion control device capable of rapid and precise stopping, starting, reversing, speed changing and positioning. The Posidyne^® Clutch/Brake being designed to handle the energy of rapid acceleration and deceleration has a field proven history under normal use demonstrating its ability to reduce maintenance normally associated with cycling applications. Use of a Posidyne^® also reduces stress on motors and other components in the machine.

The Posidyne^® is the backbone of the Force Control line of Clutch/Brake products. Constant development of new designs and materials has enabled the Posidyne^® to become a work horse on today's modern high production machinery. The basic Posidyne^® is a combination of a clutch and brake in a single unit. The multiple stacks enclosed in a cast iron housing ,cooled and lubricated by recirculating fluid are unaffected by outside contaminants and have a tremendous ability to dissipate heat. With their built in mechanical strength this makes the Posidyne^® an excellent choice for applications of heavy loads and high cycle rates.

The ABM consists of a motor with a Posistop^® Motor Brake assembled and ready to use. The ABM is available in many sizes, types and torque ranges up to 2030 Lb.Ft. By specifying the Posistop^® ABM, complete motor and brake assembly, installation time is reduced to simply mounting the motor and connecting the air supply.

The Coupler Motor Brake is designed for indexing applications where cycle rates are too low to justify a clutch/brake (roughly less than 10 CPM) or in applications where the motor must reverse. The Coupler Brake utilizes a standard Nema C-Face motor driving through a durable, keyless collet connection. Common applications include palletizers, indexing conveyors, shrink wrappers package and general material handling equipment. The Coupler Brakes are rated from 6 Ft. Lbs. to 450 Ft. Lbs. of torque.

The Posistop^® Motor Brake is available as a motor mounted unit. This Motor Brake is designed to fit brakeless brake motor frame sizes 56 to 449T. It also comes complete with the motor. (See ABM - Assembled Brake Motor) The Posistop^® Motor Brake is designed with the same proven oil shear technology which includes the patented fluid recirculation system used in the Posistop^® Clutch/Brake Units for smooth precise stops and long service life.The rugged cast iron and aluminum, totally enclosed, housings provide high heat dissipation and protects the multiple friction surfaces from hostile environments.

The Posistop^® X Class Oil Shear Motor and Coupler Brakes are designed and tested to operate over 6 million trouble free cycles with only occasional oil changes and no adjustment - ever! This unheard of life expectancy allows the Posistop^® X Class Motor and Coupler Brakes to be used on applications previously thought impossible to do using a brake.

New Posistop^® X Class Brakes let you eliminate the typical line stops, the frequent brake repairs and replacements. Here’s the reliability you need for today’s 24/7 manufacturing demands. Here’s speed and precision that can let you run at higher cycle rates and quality levels, or design new machines for higher performance.

The Positorq^® Absorber Brakes and Clutches use the same basic design of a multiple disc stack furnished with a continuous supply of cooling and lubricating fluid as do the other Force Control products. A major difference between the Positorq^® and the Posistop brake is that the Positorq^® is designed as a constant slip device and is normally force lubed for smooth torque control and energy absorption.

Tension brakes and dynamometers are essentially energy absorbers. Rotary motion is transformed through the brake to heat. Therefore, a critical function of the brake is to be able to dissipate this heat during slip. In the Positorq^®, fluid is pumped through the shaft to furnish a continuous supply of fluid to the friction surfaces. The fluid, both lubricates the surfaces at the point of contact and removes the heat. The heated fluid is then circulated through a cooling unit (either oil to water or oil to air) dissipating the heat and returned to the Positorq^®.

Since the effective radius, number of discs and friction factor remains constant, the torque available is directly equivalent to the (air or hydraulic) actuation pressure furnished to the actuating piston.
