SWITCHING

These types of brakes require DC Voltage to release. Switching can be done on either side. However for higher cycle time / faster engagement & disengagement, switching must be carried out on DC side only.
To protect contactor points, coil & switches, resistor and capacitor networks must be provided across the contactor to restrict the high restrict the inductive voltage/brake EMF which is produced when power is switched off.

Unitorq USB & UMB series brakes are absolutely fail safe in nature, and finds wide range of applications where emergency stop is required. When power fails or brake remains in engaged condition for longer periods of time, these brakes are ideal for the applications. Unitorq D.C. fail safe brake functions on an electromagnetic principle.

PRINCIPLE OF OPERATION :

When electric current is given to the stator (brake coil) the armature plate is attracted to the stator against the spring force, thus releasing the rotor. When current is cut Off, strong compression springs push the armature plate back to its original position, which clamps the rotor (friction plate) providing the braking torque. Unitorq D.C. fail brake type UMB is provided with unique manual release provision.
