Installation and commissioning
A most careful mounting and alignment of the motors on an absolutely even surface is impera-
tive to avoid distortions when the screws are being tightened. For machines which are to be
coupled it must be paid attention to a careful alignment. See Appendix 2 for alignment check.
As elastic as possible couplings should be used.
The motors with surface cooling (TEFC),
Maximum permissible coolant temperature (ambient temperature on site) acc. to EN 60034–1/IEC
60034–1 is 40
°
C (104
°
F) and a permissible altitude up to 1000 m above mean sea level (other va-
lues see rating plate).
Care must be taken that the cooling air can flow without hindrance into the air inlet openings and
freely pass through the air outlet openings and cannot be directly sucked in again. Suction and
outlet openings must be protected from obstructions and coarse dust.
Installation ans commissioning
Mounting
Fitting of pulleys or couplings.
First the shaft end should be cleaned (not with emery cloth) and then greased. Pulley or coupling
should be fitted only with the aid of a fitting device. For this purpose the threaded centering hole
in the shaft end can be used. Insert a threaded bolt into the threaded hole. Then place the steel
washer, the diameter of which is large enough to cover the hub borehole of the pulley or coupling.
The pulley and coupling is to be fitted onto the shaft end by means of a nut or a suitable hydraulic
device.
The fitting of the drive elements by means of hammer blows is not permitted because of
the risk of bearing damages.
When replacing the bearings those must only be removed and reinstalled by means of suit-
able devices using the shaft centering. Only original spare parts must be used.
The rotor of the motor is dynamically balanced.
Balance
is indicated on the shaft end face or the
rating plate (
H
= half key,
F
= full key). Take care of the balance for installation of the driving el-
ement!
The balancing of the transmission elements to be fitted must be adapted to the rotor balancing.
In case of half key balancing any
protruding and visible
part of the key has to be removed.
The motor must oand operated according to the specified mounting arrangement
