8.3.1
Checking the components
Simplified inspection/
maintenance with the
mounted brake
¾
Check release function and control Refer to Release / voltage, Page 44
¾
Measure air gap (if necessary, re-
place brake)
Refer to Checking the air
gap, Page 44
Extended inspection/
maintenance after re-
moval of brake
¾
Check the play of the rotor gear
teeth (replace worn-out rotors)
Refer to Brake replace-
ment, Page 45
¾
Check for breaking out of the
torque support at the sleeve bolts
and the armature plate
¾
Check the springs for damage
¾
Check the armature plate and
flange or counter friction surface
– Thermal damage (dark blue tar-
nish)
– Flatness depending on the size
– Max. run-in depth = rated air
gap for the size
Refer to the Design of end shield and
shaft, Page 22 table.
Refer to the General data, Page 15
table.
8.3.2
Checking the air gap
DANGER
Danger: rotating parts!
The motor must
not
run while the air gap is being checked.
1. Measure the air gap s
L
between the armature plate and the stator near the fastening screws using a
feeler gauge. (Refer to table General data, Page 15 for the values.)
2. Compare the measured air gap with the value for the max. permissible air gap s
Lmax
. (Refer to the
General data, Page 15 table for the values.)
3. Replace the brake if necessary.
8.3.3
Release / voltage
DANGER
Danger: rotating parts!
The running rotor must not be touched.
DANGER
There is a risk of injury by electrical shock!
The live connections must not be touched.
