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