4.2.2 Storing
The motors should be stored indoors in dry, dust-free rooms that are not susceptible to
vibration (v
rms
< 0.2 mm/s). The motors should not be stored for longer than two years at
room temperature (+5 °C to +40 °C) to maintain the service life of the grease.
CAUTION
Bearing damage when the motor is not operational
If the motors are stored incorrectly there is a risk of bearing damage such as brinelling, for
example as a result of vibration.
Storing indoors
● Apply a preservation agent (e.g. Tectyl) to bare, external components (e.g. shaft
extensions) if this has not already been carried out in the factory.
● Store the motor in an area that fulfills the following requirements:
– Dry, dust-free, frost-free, and vibration-free. The relative atmospheric humidity should
be less 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 against shocks and humidity.
● Make sure that the motor is covered properly.
● Avoid contact corrosion.
