B.
Temporary Storage (Up to 6 Months)
If the motor will not be put into service immediately, certain precautions should be taken to protect the motor while in
storage.
It is recommended the motor be placed under cover in a clean, dry location.
During storage, windings should be protected from excessive moisture by some safe and reliable method of heating,
such as space heaters, to keep the temperature of windings above the temperature of the surrounding air. It is
recommended the motor in storage be inspected at periodic intervals, the windings meggered and a log kept of
pertinent data. (Refer to the
OPERATION
section.) Any significant drop in insulation resistance should be investigated.
Precautions are taken by the factory to guard against corrosion. The machined parts are coated to prevent rust
during shipment. If the equipment is to be stored, examine the machined parts carefully for rust and moisture and
recoat where necessary.
Motors with oil-lubricated or oil-mist lubricated bearings are normally operated and tested in the factory with a rust-
inhibiting oil in the lubrication system. A rust-inhibiting film remains on critical bearing surfaces during transit and for
up to six months in storage. However, when the machine is received, it is recommended that the bearing oil reservoirs
on sleeve bearing motors be filled to the proper oil level with a good grade of rust-inhibiting oil. Rotate the shaft of
two-bearing machines (10 to 25 revolutions) until the journals are thoroughly coated with oil.
The bearings of grease-lubricated motors are greased at the factory with the grease cavity approximately 50% full.
Rotate the shaft of all grease-lubricated motors 10-20 revolutions at two-month intervals.
If the purchaser has specified the machine be packaged for long-term storage, the foregoing recommendations do
not apply and the packing should be left intact during the period of storage.
C.
Extended Storage (Longer than 6 months)
In the event the motor is to be stored longer than six months, please refer to GE instruction manual GEK-97427.
D.
Handling
WARNING
:
Lifting lugs on the motor are designed for handling only the motor. They are not to be
used to lift the motor plus additional equipment such as pumps, compressors or other driven
equipment. In the case of assemblies on a common base, lugs or eyebolts provided on the motor are
not to be used to
lift the assembly and base. The assembly should be lifted by a sling around the base or by other lifting means
provided on the base. In the case of unbalanced loads (such as couplings or other attachments), additional slings
or other effective means should be used to prevent tipping
.
III.
Installation
WARNING
:
Installation should be in accordance with the ‘USA-National Electric Code’ or ‘BS/EN 60204-
1’ and ‘BS/EN 60204-11’ and consistent with sound National and local practices.
Coupling, belt and
chain guards should be installed as needed to protect against accidental contact with moving parts.
Motors accessible to personnel should be further guarded by screening, guard rails, etc., to prevent them from
coming in contact with the equipment.
A.
Location
Install the motor in a well-ventilated area. Make sure there is a minimum clearance of one foot around the motor to
allow normal flow of air.
1.
Drip-proof motors are intended to be used in a well-ventilated place reasonably free of dirt and moisture.
2.
General Purpose enclosed motors can be used where they are exposed to dirt, moisture, and most
outdoor conditions.
