2. Store in a clean, dry, protected warehouse where control is maintained
as follows:
a. Shock or vibration must not exceed 2 mils maximum at 60 hertz,
to prevent the bearings from brinelling. If shock or vibration
exceeds this limit vibration isolation pads must be used.
b. Storage temperatures of 10°C (50°F) to 49°C (120°F) must be
maintained.
c. Relative humidity must not exceed 60%.
d. Motor space heaters (when present) are to be connected and
energized whenever there is a possibility that the storage ambient
conditions will reach the dew point. Space heaters are optional.
Note: Remove motor from containers when heaters are energized,
re-protect if necessary.
3. Measure and record the resistance of the winding insulation (dielectric
withstand) every 30 days of storage.
a. If motor insulation resistance decreases below the minimum
resistance, contact your Baldor District office.
b. Place new desiccant inside the vapor bag and reseal by taping it
closed.
c. If a zipper closing type bag is used instead of the heat sealed
type bag, zip the bag closed instead of taping it. Be sure to place
new desiccant inside bag after each monthly inspection.
d. Place the shell over the motor and secure with lag bolts.
4. Where motors are mounted to machinery, the mounting must be such
that the drains and breathers are fully operable and are at the lowest
point of the motor. Vertical motors must be stored in the vertical
position. Storage environment must be maintained as stated in step 2.
5. Motors with antifriction bearings are to be greased at the time of going
into extended storage with periodic service as follows:
a. Motors marked “Do Not Lubricate” on the nameplate do not need
to be greased before or during storage.
b. Ball and roller bearing (antifriction) motor shafts are to be
rotated manually every 3 months and greased every 6 months in
accordance with the Maintenance section of this manual.
c. Sleeve bearing (oil lube) motors are drained of oil prior to
shipment. The oil reservoirs must be refilled to the indicated
level with the specified lubricant, (see Maintenance). The shaft
should be rotated monthly by hand at least 10 to 15 revolutions
to distribute oil to bearing surfaces.
