Applications
The integrated brake is a spring-loaded disk brake, which is released
at a minimum air pressure of 5 bar. The brake is applied in the
absence of pressure. As soon as the control port for the brake is
placed under pressure, the piston (1) is pressurised and the spring
(2) is compressed. The motor can now start and the torque is passed
to the shaft (3). The ventilation air from the brake is connected with
the atmosphere. In order to brake the motor, the control air to the
brake is simply vented. The piston (1) is pushed to the right by the
spring (2), and the axle (3) is jammed between the two brake disks
(4).
The technology and the size of air motors with integrated running
and stationary brake make them ideal applications requiring
repeated precise positioning. The motor can also be kept stationary
in a specific position, and the stopping time for a rotating weight
can be shortened significantly. Another typical application for brake
motors is when the output shaft needs to be held in one position
when the motor stops delivering torque. The brake can handle more
than 1500 braking operations per hour at maximum braking torque.
Disassembly and Reassembly
Detach the connections with the motor and gearbox. Pull off the
motor and gearbox part. The brake disks can be lifted off after the
lock ring has been removed.
Service and Maintenance
After 20 000 braking operations as a stationary brake or 10,000
braking operations as an operating brake, the brake must be
disassembled in order to check for wear.
Warning:
If the number of braking operations is exceeded, the degree of wear
might be greater than permitted and the braking effect might be lost.
If this happens, you simply need to replace the worn brake linings.
Tests show that the brake lining needs to be replaced after approx.
90,000 braking cycles.

NOTE!
Brake motors must only ever be supplied with unlubricated
air, otherwise there is a risk of oil from the supply air getting
into the brake unit, resulting in poor brake performance or no
braking effect.
