Unpacking
If facilities for the shelter of equipment are not available, do not
unpack until ready for use. If this equipment is to be stored for any
period of time prior to installation, the area should be dry and
protected and not subject to severe humidity changes, extreme oil, dirt
and similar adverse conditions.
After unpacking and inspecting, turn the motor shaft by hand to
assure that there are no obstructions to free rotation.
Storage
Motors or generators must be stored in a clean, dry area protected
from extremes of temperature, moisture, shock and vibration. Storage
temperatures of 10 to 49 degrees C (50 to 120 degrees F) with a
maximum relative humidity of 60% must be observed. In addition,
motors subjected to extended storage must be handled and treated per
the requirements specified in publication “Motors-5.0.” This
publication is available from your Allen-Bradley Sales Office or
online at: http://www.ab.com/drives/motors.
• Bearings – Ball & Roller (anti-friction). The bearings are to be
fully greased at the time of going into extended storage. Motor
shafts are to be rotated manually every 6 months and additional
grease added purging some of that in cavity. Grease in the
bearings is to be purged at the time of removal from storage,
making sure that an ample supply of fresh grease is in each grease
cavity.
• All condensate drains to be fully operable while in storage, and/or
the drain plugs removed. The motors must be stored so that the
drain is at the lowest point. All breathers and automatic “T,”
drains must be operable to allow breathing at points other than
through the bearing fits.
• All units equipped with heaters are to have the heaters connected
if storage conditions in any way simulate or approach
atmospheric conditions experienced in operation.
• Windings to be megged at the time equipment is put in storage.
At the time of removal from storage, the resistance reading must
not have dropped more than 50% from the initial reading. Any
drop below this point necessitates electrical or mechanical
drying. Where a large quantity of motors are stored, an inspection
or sampling should be made by removing the end brackets.
Visually inspect for the presence of water in the grease or rust on
the bearing. If present, replace the bearings and relubricate.
• All external parts and motors subjected to corrosion should be
protected by corrosion resistant coating proven adequate for
prevailing conditions.
