Damage of stator due to insufficient cooling!
CAUTION
If stator that is already in use or a previously disassembled stator is assem‐
bled again, check if the separator between inlet and outlet of the coolant is
available (see fig. 12-1 ). If the stator has been commissioned without a sepa‐
rator, insufficient cooling can result in damaging the stator.

12.4.2 Preparation
Initial state: The motor lies on a clean and a flat surface.
1. Check whether the components are damaged. Damaged components
must not be mounted.
2. Provide tools, auxiliary material, measuring and test equipment and
make sure that the rotor can be mounted in a clean, dry and dust-free
environment.
3. Check all components and mounting surfaces, holes and threads, as
well as the O-ring grooves on the stator to verify that they are clean and
free from burrs. Everything must be clean, stainless and completely free
from burrs. Clean and deburr such areas if necessary.
4. Prior to assembly, clean the contact surfaces of the stators design "...-
NS-.." with a suitable cleaning agent (e.g., RIVOLTA A.C.S.3).
5. Grease the O-rings with an ordinary lubricant grease and mount the O-
rings in the stator grooves provided. Avoid twisting and soiling of the O-
rings.
6. Screw the lifting eye bolts which are required for transport in mutually
opposite threads. Check the machine construction to find out whether
longer eye bolts with distance sleeves are required.
Ensure cleanliness during all working steps!
When inserting the rotor into the stator, take the radial and axial forces
caused by magnetic force into account. Use an appropriate mounting tool to
ensure that the rotor is prevented from coming into contact with the stator
hole when it is inserted into the stator.
