APPLICATION OF THE BRAKES
Spring actuated and electromagnetically released, the disk brakes are designed for braking rotating
parts of machines. Their tasks include:
Emergency braking to provide safety function of a drive,
•
Immobilizing the actuators of machines to provide their positioning function,
•
Reducing the coasting time of drives to a minimum (safety considerations supported by
•
regulations and standards),
Constructing a self-braking motor by building it onto the electric motor - a drive unit meeting
•
the safety requirements of utilization and positioning.
Direct current brakes are characterized by simple construction, facility for regulating brake
parameters such as braking torque, braking time, and the possibility of supplying from an alternating
current source after connecting up to a rectifying system supplied on request together with the
brake, an additional feature being its quiet operation, particularly important when equipment is
operated by several drives, and operating with large frequency of actuations.
It is characterized by high operating reliability, stability of technical parameters and short braking
and release times. The brakes are made for standard direct current voltages: 24, 96, 170, 190, 215,
270 volt enabling supply from alternating current sources of 24, 110, 220, 380, 440, 500 and 600
volt while utilizing an appropriate rectifier.
