OPERATION AND MAINTENANCE MANUAL
MAC QM MOTORS

4.4 Storage

MAC QM motors can be stored for long periods (up to 2 years) without their specifications being affected. They must be stored in
a dry, dust-free place with no aggressive atmosphere or vibrations and no sudden temperature changes.
PRECAUTION
Damages caused by outdoor storage
The machine may be damaged if it is stored outdoors.
The machine must be stored only in indoor areas that meet the following conditions:
- They must be dry, dust-free, icing proof and have no vibrations. The relative humidity of the air must be below 60%; in
accordance with EN 60034-1, the temperature must not be below -15ºC.
- It must be well ventilated.
- It must provide protection against extreme bad weather.
- The ambient air must not contain aggressive gases.
The machine must be protected against knocks and humidity and its entire surface must be appropriately covered.
If the machine cannot be stored in a dry place, the following measures must be adopted:
- Cover the machine using a plastic film or similar with a drying material (silica gel) inside.
- Package the unit in a sealed box.
- Place several bags of drying agents in the sealed box. Check the drying product regularly and replace it as necessary.
- Control the humidity level in the sealed packaging by placing indicators that show the air humidity level in the packaging
at different levels.
If the machine is to be stored for a relatively long period (more than 6 months), it must be checked regularly (every 3 months) to
ensure that it is in a perfect state of repair and that there are no faults. The required maintenance work must be carried out and
the storage enclosure must be climate-controlled.
Before packaging the motor, VASCAT applies a thin film of blue removable lacquer on the end of the shaft and the machined
surfaces. This product protects the materials against corrosion. If it is to be stored for a long period, do not remove the protective
film.
PRECAUTION
Damage caused by condensation water
Condensation water may gather in the machine owing to important variations in ambient temperature, direct sunlight or high air
humidity levels during storage.
If the stator winding is damp, its insulation resistance is reduced. This leads to disruptive discharges that can destroy the
winding. Furthermore, condensation water may form oxide or mould inside the machine.
This is why it is important to follow VASCAT's storage recommendations to the letter.
