A power motor brake (commonly referred to as an electric brake) is a safety feature incorporated into many modern power tools, such as circular saws, drills, and miter saws. Many manufacturers implement this feature into tools specifically with a spinning blade or cutter.
Designed with Essential oil Shear Technology, the Posistop and MagnaShear Motor Brakes are powerful stopping brakes designed to mount on the back of a brakeless brake engine. They can survive the harsh conditions of mining, manufacturing, material handling in addition to packaging and food digesting with minimal maintenance and no adjustment-ever. The totally enclosed rugged housings maintain dirt and moisture out while reducing noise and extracting heat.
The motor mounted brakes could be furnished three ways: (1) mounted on a NEMA or IEC frame engine, (2) furnished as an assembled brake motor with electric motor and brake assembled, (3) or with a special flange to install to other 
flanges such as a gear reducer.
