9. Use a test run (starting at low rotation speeds) to
check the correct concentricity of the rotor.
When machines are flexibly suspended, pronounced
radial and longitudinal movements may occur. If the
movements exceed the permissible limits (see
Specifications, Page 91ff) you must make sure that the
'
stator follows the rotor s sequence of motions.
When couplings are used, there is a possible longitudinal
and radial play to be taken into account.
