Rotor replacement
Danger!
Disconnect voltage. The brake must be free of residual torque.
1. Loosen connection cable.
2. Loosen the screws evenly and remove them.
3. Completely remove the stator from the endshield. Observe the supply cable.
4. Pull rotor from hub.
5. Check hub toothing.
6. In case of wear, the hub must also be replaced.
7. Check the friction surface at the endshield. In case of strong scoring at the flange,
replace the flange. If scoring occurs at the endshield, re-finish endshield.
8. Measure the rotor thickness (new rotor) and head height of the threaded sleeves using
a caliper gauge.
9. Calculate the distance between stator and armature plate as follows:
Distance = Rotor thi s
Lürated
- head height
(”s
Lürated
” see table chapter 3.3 )
10. Evenly loosen the threaded sleeves until the calculated distance between stator and
armature plate is reached.
11. Install and adjust new rotor and stator (see chapter 4.3.2).
12. Reconnect the supply cable.
