Maintenance
6.3.2 Replacing the rotor
Warnung!
Turn the power supply off. The brake must be torque-free.
1. Disconnect the power supply cable.
2. Undo the screws evenly and remove them completely.
3. Remove the entire stator from the end shield. Observe the power supply cable.
4. Pull the rotor off the hub.
5. Check hub teeth.
6. Replace the hub as well if worn.
7. Check the end shield friction surface. If it and/or the flange is heavily scored, replace either or
both. If the end shield is heavily scored, rework the friction lining or install a friction plate.
8. Measure rotor thickness (new rotor) and sleeving screw head height with a caliper gauge.
9. Calculate the gap between the stator and the armature plate as below.
Gap = rotor thickness + s Lürated - head height
(s Lürated , see chapter 3.2 )
10.Undo the sleeving screws evenly until the calculated gap between stator and armature plate
is reached.
11.Mount the new rotor and brake and adjust them (see chapter. 4.3.2).
12.Re-connect the power supply cable.
6.3.3 Replacing the entire stator

1. Disconnect the power supply cable.
2. Undo the screws evenly and remove them.
3. Take the entire stator off the end shield. Observe the power supply cable.
4. Install the new stator and adjust it (see chapter 4.3.2)
