Omega Electromagnetic Brakes

In any application where instantaneous stopping of machinery or equipment of rotary type is necessary, ‘OMEGA' Electro Magnetic Brake is inevitable.

Electro Magnetic Brakes have found vast use on Hoists, Cranes and Winches; in Paper, Rubber, Steel, Textile, Cement, Sugar, Mining & other industries; in Machine tools, printing machinery etc. and in many other types of equipment.

Its 'Fail Safe' characteristic renders it very essential for material handling equipments like Hoists, Cranes, and Elevators etc.

We manufacture Spring Loaded Disc type brakes suitable for A.C. Single phase/Three phase 50cycle power supply. Normally the brake is in "Brake ON" position. Brake is OFF (Brake-OFF) when power is supplied Braking action automatically takes place (i.e. Brake-ON) when power supply is cut off or power failure occurs.

CONSTRUCTION:

As the name suggests, it works on electromagnetic principle and consist of an electromagnet fixed to the end plate, a floating plate on one side of which is fixed the armature, a friction plate with either a square hole or internal spline at its centre, and the mounting plate and a square piece of shaft or spline shaft. The square centre piece is keyed to the motor shaft. The friction plate rotates with the motor shaft but is free to float axially on the square shaft. Normally, due to spring pressure, the friction plate is, held tight between the mounting plate and the floating plate and brake is 'ON’ When the current is supplied to the electro magnet the magnet attracts the floating plate against spring, pressure, thus releasing the brake, i.e. Brake is 'OFF'. This brake is very ideal for mounting directly on the motor flange and no separate foundation is necessary to fix the brake.

The brake can also be supplied with twin or triple- friction discs for higher torque capacity, and can be provided with manual release mechanism, if necessary, Manual release mechanism is inevitable if the brake is to be used on hoisting gear of crane, winch or hoist.

For assessing the size of "OMEGA' brake required for a particular application, it is necessary to know the H. P. of the equipment and the speed of the shaft in R. P. M. where the brake is to be mounted. The following formula enables calculating the average breaking torque required for the equipment.
