Component Cause Effect Influencing factors
Friction lining Emergency stops Wear on the
friction lining Applied friction energy
Overlapping wear when the drive
starts and stops
Active braking by the drive motor
with the help of the brake (quick
stop)
Starting wear if motor is mounted
in a position with the shaft vertical,
even if the brake is open Number of start−stop
cycles
Armature plate and
flange Rubbing of the brake lining Running−in of armature
plate and flange Applied friction energy
Teeth of the brake
rotor Relative movement and impacts
between brake rotor and brake hub Teeth wear (primarily at
the rotor end) Number of start−stop
cycles,
level of the braking
torque
Armature plate
bracket Load changes and impacts due to
reversal error during interaction
between armature plate, cap
screws and guide bolts Armature plate, cap
screws and bolts are
deflected Number of start−stop
cycles,
level of braking torque
Springs Axial load cycle and shearing stress
on the springs due to radial
reversed error of the armature plate Fatigue failure
of the springs Number of switching
operations of the brake
