MagnaShear motor brakes are ideal for mining applications where the motor is stopped, or reversed, each cycle such as loaders/unloaders, conveyors, rail car spotters and dumpers, overland and internal tripper cars, rotary coal sweep samplers, and more.  

These proven motor brakes are available to accommodate a wide range of applications. Spring set torque ratings from 3 to 1250 foot-pounds are available.  The MagnaShear motor brakes can be sized to the correct torque value independent of the motor frame size or horsepower by changing the combination of springs and friction discs.

MagnaShear motor brakes feature a “quick mount” feature for quick and easy mounting to drive motors in NEMA frame sizes 56 to 449 or some IEC frame motors. They are shipped ready to install, with no assembly or adjustments required.  

MagnaShear motor brakes can be furnished as a complete motor and brake assembly (assembled brake motor), or to mount on a machine frame or other special mounting configuration.  

These proven motor brakes are totally enclosed from outside contaminants, with seal integrity for harsh and washdown environments. A modular design /assembly allows for ease of servicing and maintenance.  

Hazardous duty units for class II, Group a, b, c, d, e and f are also available, as well as low temperature or Artic duty down to -40 degrees.

The totally enclosed MagnaShear motor brakes are impervious to moisture, dirt and dust that is common in mining applications, as well as concrete block plants, asphalt shingle manufacturing, bulk material handling, forest products manufacturing, and more.
