Storing indoors
● Store the motor in an area that meets the following criteria:
– Dry, dust-free, frost-free and vibration-free The relative air humidity should be lower
than 60% and the temperature should not drop below -15 °C in accordance with
EN 60034-1.
– Well ventilated
– Offers protection against extreme weather conditions
– The air in the storage area must not contain any harmful
gases. ● Protect the motor from shocks and humidity.
Protection against humidity
● If a dry storage area is not available, then take the following precautions:
– Wrap the motor in humidity-absorbent material and then wrap it in film to create an air
tight unit.
– Place a humidity meter inside the film wrapping.
– Inspect the motor regularly.

Long-term storage
If you are storing a motor for more than six months, you must check its condition every six
months.
● Check the motor for damage.
● Carry out any necessary maintenance work.
● Document all preservation measures taken so that they can be reversed before the
machines are put back into service.
● Energize anti-condensation heaters (if provided) or otherwise provide a constant
source of low heat to the motor windings, along with forced air ventilation.
Condensate
Condensate can collect in the motor as a result of sharp fluctuations in ambient temperature,
exposure to direct sunlight, high levels of humidity in the storage location or intermittent
operation/variations in load during operation. Make sure that the storage conditions are such
that condensate cannot form in the motor.
CAUTION
Damage due to condensate
If the stator winding is damp, its insulation resistance is reduced. This results in voltage
flashovers, which can destroy the winding. Condensate can also cause rust to form inside
the motor.
Ensure that condensate can drain away.
