as for interrupted operation. For this reason, the brake can be:
Released electromagnetically for unlimited period both during resting of the drive system
•
(n=0) as well as during rotation (n>0)
Utilized in interrupted operation with large number of actuations (brakings)
•
The maximum speed at which the brakes can be utilized is 3000 RPM, any direction of rotation.
BRAKE INSTALLATION
Proceed with installation of the brake after checking:
That the motor or equipment cooperating with the brake has the appropriate anti-friction
•
surface for the brake disk, which is particularly important for brakes without the mounting
disk, this surface should be
free from dirt that could
affect the braking torque, e.g.
oil, grease, etc.
For correct preparation of
•
motor elements for mounting
the brake, for brakes without
the mounting disk the motor
bearing shield (15) in Fig. 5.
must have threaded holes
for screwing in the brake
mounting bolts, whereas
for brakes cooperating with
motors where a mounting
disk is required - the bearing
shield (15) must have
threaded holes enabling
screwing in the bolts securing
the brake mounting disk (9) -
Fig. 6.
That the motor shaft has the
•
thrust surface for mounting
the brake gear wheel, along
with slot and prismatic key
of length not less than the
length of the gear wheel,
That the motor shaft has the
•
groove and circlip securing
the gear wheel against axial
shifting,
For conformity of brake rated voltage with the voltage available in the supply circuit,
•
For the possibility of effective earthing or neutralizing by metallic connection of the brake
•
with the motor or the equipment to which the protection conductor is connected,
For complete set of parts and their technical state,
•
For the capability of free flow of air cooling the self-braking motor.
•
After ascertaining that all the conditions for proper mounting are satisfied, proceed with installation
of the brake. The sequence of tasks while installing the brake should proceed as follows:
