The MagnaShear motor brake from Force Control Industries utilizes oil shear technology to transmit torque between lubricated surfaces. This innovation eliminates heat build-up associated with dry brakes, a significant cause of conveyor fires.
A patented fluid recirculation system, noted the manufacturer, dissipates the heat and keeps the brakes running cool.
In addition to being safer, the OEM said that oil shear technology eliminates wear on friction surfaces, significantly increasing service life and virtually eliminating adjustment in demanding mining applications. In addition to conveyors, MagnaShear motor brakes are ideal for applications where the motor is reversed each cycle such as loader/unloader conveyors, as well as cranes, winches, and hoists, rail car spotters and dumpers, rotary samplers, trippers, and pallet return conveyors.
The oil shear technology also provides a smooth “cushioned” stop, which reduces shock to the drive system, further extending service life of downstream components.
MagnaShear motor brakes feature “quick mount” features for quick and easy mounting to drive motors in NEMA frame sizes 56 to 449. They are shipped ready to install, with no assembly or adjustments required. The brakes are also available pre-mounted on a motor for severe duty applications.
