1.7 Maintenance
WARNING:
1.7.1 General inspection
1.
Inspect the motor at regular intervals, at least once a year. The frequency of checks depends on, for example,
the humidity level of the ambient air and the local weather conditions. This can initially be determined
experimentally and must then be strictly adhered to.
2. Keep the motor, fan grid and filters clean and ensure free ventilation airflow, when present, and cooling. If the
motor is used in a dusty environment, the ventilation system must be regularly checked and cleaned. M3FT
motors are equipped with a filter that can be replaced or cleaned. The filter material characteristics are shown
in the table below. Liquid cooled motors require a clean fluid, and filters in the cooling circuit must be present
and regularly inspected.
3.
Check the condition of the shaft seals (e.g., V-ring or radial seal) and replace if necessary.
4. Check the condition of connections and mounting and assembly bolts.
5. Check the condition of the bearings by listening for any unusual noise, by measuring vibration and bearing
temperature, and by inspecting spent grease or SPM bearing monitoring. Pay special attention to bearings
when their calculated rated life is coming to an end.

When signs of wear are noticed, dismantle the motor, check the parts and replace if necessary. When bearings are
changed, replacement bearings must be of the same type as those originally fitted. The shaft seals must be replaced
with seals of the same quality and characteristics as the originals when changing bearings.
1.7.1.1 Standby motors
If the motor is in standby for a longer period of time on a ship or in another vibrating environment, the following
measures have to be taken:
1.
The shaft must be rotated regularly every two weeks (to be reported) by means of starting up the system. If
startup is not possible for any reason, at least the shaft must be turned by hand in order to achieve a different
position once a week. Vibration caused by other equipment on the vessel will cause pitting of the bearing,
which should be minimized by regular operation / hand turning. If the motor is equipped with a parking brake,
this has to be energized before turning the shaft.
2. The bearing must be greased while rotating the shaft every year (to be reported) – this is not applicable to
motors with permanently lubricated, sealed bearings. If the motor has been supplied with a roller bearing at
the driven end, the transport lock must be removed before the shaft is rotated. The transport locking must be
remounted before any transportation.
3. All vibration must be avoided to prevent the bearings from failing. All instructions in the motor instruction
manual for commissioning and maintenance must also be followed. The warranty will not cover damage to the
windings and bearings if these instructions have not been followed.
1.7.2 Lubrication
WARNING:
A MOTOR WITH A FREQUENCY CONVERTER SUPPLY MAY BE ENERGIZED EVEN IF
THE MOTOR IS AT A STANDSTILL.
