8.3.1 Checking the component parts
8.3.2 Check the rotor thickness
1. Remove the fan cover.
2. Remove the cover ring, when present.
3. Measure the rotor thickness using a calliper gauge. For the friction-plate version: observe the edging on
outer diameter of friction plate.
4. Compare the measured rotor thickness with the minimum permissible rotor thickness (values: 17).
If the measured rotor thickness is insufficient, the rotor must be replaced completely.
Description:
61.
8.3.3 Check the air gap
1. Measure the air gap "s
L
" between the armature plate and the stator near the fixing screws using a feeler
gauge (values: 17).
2. Compare the measured air gap to the value for the max. permissible air gap "s
Lmax
" (values: 17).
3. Adjust the air gap to "s
LN
" ( 60).
With mounted brake
❚ Check release function and control
❚ Measure the air gap (adjust if required)
❚ Measure the rotor thickness (replace rotor if required)
❚
Thermal damage of armature plate or flange (dark-blue tar-
nishing)

After removing the brake
❚ Check the play of the rotor gear teeth (replace worn-out
rotors)
61
❚ Check for breaking out of the torque support at the sleeve
bolts and the armature plate
❚ Check the springs for damage
❚ Check the armature plate and flange or bearing shield
- Evenness depending on the size
- Max. run-in depth = rated air gap for the size

DANGER
Danger: rotating parts!
The motor must not be running when checking the rotor thickness.
