3. Handling
3.1 Reception check
Immediately upon receipt, check the motor for external
damage (e.g. shaft, -ends and flanges and painted
surfaces) and, if found, inform the forwarding agent
without delay.
Check all rating plate data, especially voltage, winding
connections (star or delta), category, type of protection
and temperature class. The type of bearing is specified on
the rating plate of all motors except the smallest frame
sizes.
In the case of a variable speed drive application, check the
maximum loadability allowed according to the frequency
stamped on the motor’s second rating plate.
3.2 Transportation and storage
The motor should always be stored indoors (above
–20 °C) in dry, vibration-free and dust-free conditions.
During transportation, shocks, falls and humidity should be
avoided. In other conditions, please contact ABB.
Unprotected machined surfaces (shaft-ends and flanges)
should be treated against corrosion.
It is recommended that shafts are rotated periodically by
hand to prevent grease migration.
Anti-condensation heaters, if fitted, are recommended to
be energized to avoid water condensing in the motor.
The motor must not be subject to any external vibrations
exceeding 0.5 mm/s at standstill so as to avoid causing
damage to the bearings.
Motors fitted with cylindrical-roller and/or angular contact
bearings must be fitted with locking devices during trans-
port.
3.3 Lifting
All ABB motors above 25 kg are equipped with lifting lugs
or eyebolts.
Only the main lifting lugs or eyebolts of the motor should
be used for lifting the motor. They must not be used to lift
the motor when it is attached to other equipment.
Lifting lugs for auxiliaries (e.g. brakes, separate cooling
fans) or terminal boxes must not be used for lifting the
motor.
Because of different frame lengths, mounting arrange-
ments and auxiliary equipment, motors with the same
frame may have a different center of gravity
Damaged lifting lugs must not be used. Check that
eyebolts or integrated lifting lugs are undamaged before
lifting.
Lifting eyebolts must be tightened before lifting. If needed,
the position of the eyebolt can be adjusted using suitable
washers as spacers.
Ensure that proper lifting equipment is used and that the
sizes of the hooks are suitable for the lifting lugs.
Care must be taken not to damage auxiliary equipment
and cables connected to the motor.
Remove eventual transport jigs fixing the motor to the
pallet.
Specific lifting instructions are available from ABB.
WARNING!
During lifting, mounting or maintenance work, all
necessary safety considerations shall be in place and
special attention is to be taken so that nobody will be
subject to lifted load.
3.4 Motor weight
The total motor weight can vary within the same frame size
(center height) depending on different output, mounting
arrangement and auxiliaries.
The following table shows the estimated maximum
weights for motors in their basic versions as a function of
their frame material.
The actual weight of all ABB’s motors is shown on the
rating plate.

If the motor is equipped with a brake and/or separate fan,
contact ABB for the weight.
