2. Handling

2.1 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 and winding
connection (star or delta). The type of bearing is specified
on the rating plate of all motors except the smallest frame
sizes.

2.2 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 used to avoid water condensing in the motor.
The motor must not be subject to any external vibrations 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
transport.

2.3 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.

ABB Motors and Generators | Low voltage motor manual 01-2009
Motors with the same frame may have a different center of
gravity because of different output, mounting arrangements
and auxiliary equipment.
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.

2.4 Machine weight

The total machine weight can vary within the same
frame size (center height) depending on different output,
mounting arrangement and auxiliaries.
The following table shows estimated maximum weights
for machines in their basic versions as a function of frame
material.
The actual weight of all ABB's motors, except the smallest
frame sizes (56 and 63) is shown on the rating plate.
