eMotors Direct’s stock of brake motors are for heavy-duty applications where quick stopping time is a requirement. While your average motor will coast to a stop once power is disconnected, brake motors are standard motors that have been modified with an electromagnetic electric motor brake that works to stop the motor within a limited amount of time. You’ll often find these single and three-phase brake motors on cranes, saws, grinders, and conveyors, applications where a quick stop is required for personnel safety and equipment mechanical integrity.
