Force Control's MagnaShear motor brake features oil shear technology
The MagnaShear motor brake from Force Control Industries employs oil shear technology. Oil shear technology includes a layer of automatic transmission fluid between the brake disc and the drive plate. As the fluid is compressed, the fluid molecules shear – thus imparting torque to the other side. This torque transmission causes the stationary surface to turn, bringing it up to the same relative speed as the moving surface.
In addition to transmitting torque, a fluid recirculation system helps to dissipate heat. Along with heat removal and torque transmission, the fluid serves to lubricate all components of the oil shear brake.
Spring set torque ratings from 3 to 1,250 foot-pounds are available. MagnaShear motor brakes can be sized to the correct torque independent of the motor frame size or horsepower.
MagnaShear motor brakes feature “quick mount” features for mounting to drive motors in NEMA frame sizes 56 to 449. They are also available pre-mounted on a motor for severe-duty applications. MagnaShear motor brakes can be furnished to fit a NEMA or IEC frame motor, as a complete motor and brake assembly, or to mount on a machine frame or other special mounting configuration.
The motor brakes are totally enclosed from outside contaminants, with seal integrity for harsh and washdown environments.
