The Problem - Heat Buildup
Heat buildup, the mortal enemy of electric motors can destroy conventional
motor brakes. Although heat is the natural product of the braking process,
increased starts and stops of the electric motor create intense heat in
conventional brake devices. Often heat buildup damages the brake as well
as the electric motor - and frequently causes failure of the entire system.
This can mean increased downtime - as well as higher maintenance costs.
Conventional brake devices can take the heat from industrial motors, but they sacrifice friction material
with each stop. They deteriorate with repeated use. Even though the motor
is spared the stress of excessive braking heat, the brakes require routine
maintenance such as coil and friction material replacement.
The result of heat buildup
- Breakdowns. Dry brakes have a short life, suffer from increased wear
and may cause downtime losses that come from frequent maintenance and
replacement.
The Solution - Posistop® Brakes
Posistop® Oil Shear Brakes are designed to dissipate
the heat buildup that destroy conventional braking devices. The Posistop® absorbs the energy generated by the braking action and controls the heat
buildup - thus providing greater reliability and repeatability, as well
as heat dissipation.
Unlike conventional motor brakes, the Posistop® is
a multiple surface device that operates on a spring activated, pressure
release system. Its multiple disc stack and internal oil pump helps to
eliminate the need to replace coils and friction material - and reduce
the heat on any one friction surface.
