5. General Motor Procedure:
If the motor is not put into service immediately, the motor must be stored in a clean, dry, warm location. Minimum
temperature of 50°F. (10°C,). Several precautionary steps must be performed to avoid motor damage during storage.
a. Use a “Megger” each month to ensure that integrity of the winding insulation has been maintained. Record the
Megger readings. Immediately investigate any significant drop in insulation resistance.
b. DO NOT lubricate the motor bearings during storage. Motor bearings are packed with grease at the factory.
c. If the storage location is damp or humid, the motor windings must be protected from moisture. This can be done
by applying power to the motor’s space heaters, (IF AVAILABLE) while the motor is in storage. If the motor does
not have space heaters, storing it in a damp or humid location will, very quickly, cause internal corrosion and
motor failure which is not warranted.
NOTE:
For specific storage instructions, for the actual
motor and any accessory parts that were supplied, refer to
the manufacturer’s instructions.
