The end user has full responsibility for preparation
of the foundation.
Metal foundations should be painted to avoid
corrosion.
The foundations must be even (see the image
below) and sufficiently rigid to withstand any
short circuit forces. They must be designed and
dimensioned to prevent vibration from being
transferred to the motor, as well as any vibration
caused by resonance.
Balancing of the motor has been carried out
standard using the half key balancing method.
Coupling halves or pulleys must be balanced after
the keyways are machined. Balancing must be
done in accordance with the balancing method
specified for the motor.
HDP motors for frame sizes 250, 280, 315, 355
and 400 are designed according to IEC 60034-7
for both IM B3 and IM B35 installation.
Correct alignment is essential to avoid bearing,
vibration and possible shaft failures.
Mount the motor onto the foundation and/or
the mounting flange using appropriate bolts
or studs, and place shim plates between the
foundation and the feet.

Note! Height difference shall
not exceed ± 0,1 mm from
any other motor foot.

Coupling halves and pulleys must be fitted onto
the shaft using suitable equipment and tools
which do not damage the bearings or the seals.
Never fit a coupling half or pulley by hammering,
and never remove one using a lever pressed
against the body of the motor.
Align the motor using appropriate methods.
Re-check the alignment after final tightening of
the bolts or studs.
Do not exceed the permitted loading values for
bearings stated in the product catalogs.
