Brakes and Clutches

Hysteresis Brakes

ERA, ERB & ERC series Spring-operated brakes are brakes with two friction surfaces. When no current is applied, the brake force is generated by means of several coiled pressure springs. When current is applied, the brakes are released electromagnetically. While braking, the rotor, which is axially movable on the hub, is pressed against the adaptor by means of the springs acting on the armature plate. In case of braking, an air gap ‘s’ occurs between the armature plate and the stator assembly. To release the brake, the coil in the body is excited by application of DC current. The resulting magnetic field via the magnetic flux path causes the armature plate to be pulled towards the stator assembly against the spring force; thereby releasing the rotor. Rotor Assembly consist of: Rotor, Friction plate Stator Assembly consist of: Body, Coil
