Demag B003 and B680 disc brakes are double-surface spring-actuated brakes
featuring electro-magnetic brake release. The brake fitted under the fan cover can
be controlled independently of the motor and causes no axial movement of the
rotor shaft or forces on the bearings.
The diagrams show the function elements of the disc brakes, which are spring-
actuated with electro-magnetic release.
When the voltage supply to the brake coil is interrupted, the brake is applied. This
operating principle is also known as a safety brake.
B003 to B680 brakes are controlled as standard by a brake module integrated
in the terminal box of the motor. Brake sizes B003 to B050 can also be fed by a
separate supply to the coil.
Two brake sizes are possible for each motor frame size to cover a large brake
torque range for various applications.
The brake is provided with IP 54 enclosure as standard. If the enclosure type is
increased to IP 55/IP 65, an additional covering tape (15) must be used, which
is fitted to an additional retaining plate (16) for ZBF 80 - 132 units. Supporting
washer (17) is added to shaft sealing ring with worm spring (7), the intermediate
space is filled with grease. An additional plastic washer (18) is fitted beneath
adjusting nut (12).
