3 Receipt, transport and storage
3 .1 Receipt and transport
Upon receipt and for transport:
• Use transport locks for all transport operations .
• Avoid moisture and shocks during transport .
• Check the motor for external damage .
• If damage is found, inform the sales representative of
Hoyer Motors .
• Check all nameplate data and compare it with the re-
quirements for the motor .
• Remove transport locks if present .
• Turn the shaft by hand to check for free rotation .
3 .2 Storage
• Ensure the use of correct lifting lugs . Lifting lugs are
dimensioned for the weight of the motor .
• Do not apply extra weight .
• If necessary, use suitable special equipment such as
lifting gear and ropes .
• Store in a dry, dust-free and vibration-free location .
• Carefully consider long-term storage procedures .
Short-term storage (less than 2 months)
The motor should be stored in a place with a controllable
environment . A good warehouse or storage location has:
• Measure the insulation resistance and temperature
of the windings to check whether the motor has been
stored improperly, even for a short time .
• A stable temperature, preferably in the range from 10°C
(50°F) to 50°C (120°F) . If the anti-condensation heaters
are energised and the surrounding air is above 50°C
(120°F), ensure that the motor is not overheated .
• Low air humidity, preferably below 75% . The motor
temperature must be kept above the dew point shown
in the figure to prevent water vapour from condensing
inside the motor . If the motor is equipped with anti-
condensation heaters, they should be energised . Proper
operation of the anti-condensation heaters must be
checked periodically . If the motor is not equipped with
anti-condensation heaters, other methods of heating
the motor must be used to prevent water vapour from
condensing in the motor .
• A stable support free from excessive vibration and
shocks . If vibration levels are expected to be too large,
the motor should be isolated by placing suitable rubber
blocks under the motor feet .
• Air that is ventilated, clean and free from dust and cor-
rosive gases .
• Protection against harmful insects, vermin and chemi-
cals .
Long-term storage (more than 2 months)
In addition to the measures described for short-term stor-
age, the following actions are necessary:
• Measure the insulation resistance and temperature
of the windings to check whether the motor has been
stored improperly, even for a short time .
• Check the condition of the paintwork every three
months . If corrosion is seen, remove it and apply a new
coat of paint .
• Check the condition of the anti-corrosion coating on
bare metal surfaces every three months . If corrosion is
seen, remove it gently with emery cloth and apply an
anti-corrosion coating .
• Provide small ventilation openings if the motor is
stored in a wooden crate . Prevent water, dust and in-
sects from entering the crate .
