A power motor brake (commonly known as an electric brake) is a safety feature incorporated into many contemporary power tools, such as 
circular saws, drills, and miter saws. Many manufacturers put into action this feature into tools specifically with a spinning blade or cutter.
Designed with Oil Shear Technology, the Posistop and brake motor MagnaShear Motor Brakes are powerful stopping brakes made to mount on the back of a brakeless brake engine. They are able to survive the harsh environments of mining, manufacturing, materials handling and also packaging and food digesting with minimal maintenance and no adjustment-ever. The totally enclosed durable housings keep dirt and moisture out while reducing noise and extracting heat.
The motor installed brakes can be furnished 3 ways: (1) installed on a NEMA or IEC frame engine, (2) furnished as an assembled brake engine with electric motor and brake assembled, (3) or with a particular flange to install to other flanges such as a gear reducer.
