Material : Mild Steel

TYPICAL APPLICATIONS : Textile Machines, Material handling equipments, Conveyors, Machine Tools, Glass making Machines, Marble Cutting Machines, Stone Polishing Machines, Photocopiers, Packaging Machines... etc. WORKINGFlange mounted clutches are normally off type and operate on DC voltage. On applying DC voltage to the stator (coil) strong magnetic filed is produced, which pulls the armature towards the friction material of the rotor over the air gap and torque gets transmitted free of back lash.On switching off power supply, the unique prestressed spring pulls the armature back into the original position and clutch is positively released free from residual torque. SWITCHINGNormally off type clutches operate on D.C. voltage, hence A.C. to D.C. conversion is done by means of a suitable rectifier.Switching of the clutch can be on either side. However, once application demands, higher switching frequency / faster engagement and disengagement time, switching must be carried out on D.C. side. To restrict the high inductive voltage / back EMF a suitable supressor and capacitor network is provided across the contactor coil.

Stator2. Coil3. Friction Lining4. Armature Plate5. Leaf Spring6. Flanged Hub WORKING These type of brakes are normally-off type and operates on power. When power is given to the stator (coil), the armature is attracted towards the asbestos free friction liner of the brake stator which clamps the rotating component stop at once.On switching off the electric power, the unique prestressed spring pulls the armature plate back into its original position and brake positively released with no residual torque.   SWITCHING Normally off type clutches operate on D.C. voltage, hence A.C. to D.C. conversion is done by means of a suitable rectifier.Switching of the brake can be on either side. However, once application demands, higher switching frequency / faster engagement and disengagement time, switching must be carried out on D.C. side. To restrict the high inductive voltage / back EMF a suitable supressor and capacitor network is provided across the contactor coil.

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.

On applying DC voltage to the stator (coil) strong magnetic filed is produced, which pulls the armature towards the friction material of the rotor over the air gap and torque gets transmitted free of backlash.On switching off power supply, the unique prestressed spring the armature back into the original position and clutch is positively released free from residual torque.

Etc.     brake motors are used for various application where instantaneous stopping of the driven load is required. The operation of the brake is "fail safe type" (usb & umb series) and are normally on. The brake is applied when power to the motor is switched off or power failure occurs. constructionbrake motor is combination of an ac induction motor and an electromagnetic dc fail safe brake.as shown in the figure brae motor consists of the following : ac induction motor (foot/flange) electromagnetic dc fail safe brake type usb or umb. cooling fan after the brake for better heat dissipation and cooling of motor & brake as well. rectifier unit either can be provided near to motor terminal (for ac switching) or given separately to mount them in the control panel (for dc switching). manual release is an optional feature and will be provided only with our umb series brakes. workingwhen there is no power given to either motor or brake, the brake torque is provided by compression springs developing an axial force on the brake armature plate which ultimately presses it against mounting flange. In this condition a nominal "air gap" will be available and the rotor with the frictional surfaces remains sandwiched in between armature plate anf mounting plate.pelease of the brake takes place, when the power to the brake and motor is supplied at the same tme. Power to the brake coil produces strong magnetic filed and pulls the armature plate against the compression spring force towards the stator (brake coil) over the air gap and rotor becomes free to rotate. The attraction of the armature plate and returning to it's original position takes place instantaneously thus failsafe nature is ensured in case of power failure.
