Spring Applied EM Brakes for Brake motors
REACH Spring applied electromagnetic brake is a single disc brake with two friction plate surfaces. The motor shaft is connected with the spline hub via flat key, and the spline hub is connected with friction disc components through spine.
When stator is powered off, the spring generates forces upon armature, then the friction disc components will be clamped between armature and flange to generate braking torque. At that time, a gap Z is created between armature and stator.
When brakes need to be released, the stator should be connected DC power, then the armature will move to the stator by electromagnetic force. At that time, the armature pressed the spring while moving and the friction disc components are released to disengage the brake.
The braking torque can be adjusted by adjusting ring A-Type Brake.
