Formerly produced by Eaton Dynamatic, the electromagnetic friction brake works on the principle of an electromagnet. It consists of two basic parts: The field magnet and the armature plate. When a D.C. voltage is applied to the coil, located inside the field magnet, the armature plate is attracted to the field magnet. By means of friction contact between the two members, torque is transmitted. The friction material located in the field magnet helps to stabilize the torque output and prolong the wear life of the brake.
