DC Spring Applied

BrakeType 14.458 (Normally On)

SwitchingBrake coils are operated with DC voltage. Generally

when braking time is not critical AC side switching is

done. This method is often used with brake motors,

where brake is switched with motor contacts. Due to the

inductance of the brake coil, engagement time can be

3 to 6 times longer than with DC switching. Therefore

this arrangement is not suitable for hoist applications.

For falling loads such as hoist, lifts and cranes, also the

high inertia loads, a brake motor to some extent

regenerate the supply and hold off the brake. Here it is

essential to switch on the DC side of the rectifier. DC side switching requires provision of

universal spark suppressor and capacitor to protect the coil and switches against inductive

voltages.

For normal rectifier converting AC to DC you can use separate universal spark suppressor

and capacitor across the switch. Rectifier supplied by us are designed to include

suppressor and capacitor suitable for DC switching.

For optimum performance we suggest the following Rectifiers (Power supply).

Working

The engagement times are valid for switching on DC side. The table shows the delay during engagement t11, the rise time of brake torque t12

and the engagement time t1=t11 + t12. Disengagement time is not influenced by DC or AC side switching. However it can be reduced by

suitable excitation or over excitation.

Selection

1. Select basic brake according to the torque.

Torque (Nm) = 9550 X (Motor kW / RPM) X Safety factor (K)

2. Describe the brake with the ordering parameter. (Type, size, operating voltage and hub bore)

3. Choose optional extras required (G pcd, tacho mounting provision, friction plate (instead of mounting flange), with microswitch).

4. Choose appropriate safety factor for the hoist, lift, inclined conveyors or equipment where holding against gravity is required.

5. Select proper Rectifier considering rated voltage of the brake. If coil operatingvoltage is 96 or 190 VDC you can use our rectifier.(Call for product details).

6. Choose correct input AC voltage for rectifier.

Brake Size t11ms t12ms t1ms t2ms

In the “power off” state the compression

springs (5) press the armature disc (3)

and rotor (7) against attachment surface.

Hub (8) is firmly locked on the shaft and

rotor slides over the hub.

On applying rated direct current voltage

to the stator (2) the magnetic field

produced will pull the armature disc (3)

over air-gap ‘a’ towards stator against

spring force. Thus the rotor is released

allowing shaft to rotate.

In the event of continuous power failure,

rotor (7) can be freed by pulling the hand

release (14) - the hand release of

“ deadman type”. The hand release goes

back automatically to its original position

and brake will immediately revert to its

safe action.
