High voltage motor storage and protection

Store the motor in a clean, dry place and cover it as much as possible. If the storage location is cold, humid, or subjected to severe temperature changes, keep the motor winding temperature a few degrees above ambient temperature to prevent condensation and moisture absorption. The heater can be energized (when with a heater) or a few bulbs placed in the base and energized to squirt.

Cover the motor with a tarpaulin to prevent dust on site, but plastic sheets are not recommended. The insulation resistance is measured every one month to verify the effect of storage protection. Significant changes in insulation resistance are usually caused by moisture, and storage conditions should be considered.

Although the winding insulation itself has excellent moisture resistance, proper consideration should be given to preventing the winding from getting wet when the motor is not in use. This protection also prevents rusting of the core and corrosion of exposed metal parts. If the storage location is cold and humid and the motor has a heater, the heater should be energized.

For motors with thin oil lubricated bearings, a special rust preventive oil has been left in the bearing reservoir before packaging. It is best to replace it with the same special anti-rust oil every 3 months until the motor is put into normal use.

Note that there is usually a rotor fixture on the shaft to prevent the rotor from moving when the motor is being moved. This fixture must be removed before the motor is energized or the shaft is turned. Also, the motor must be reinstalled before being transported from the storage to the final use position.
