Lubrication intervals
The lubrication interval is defined by following the
L1-principle. This means that 99% of ABB's motors
will achieve the normal service intervals. Values for the
lubrication intervals can also be calculated according
to the L10-principle, which are normally doubled
compared to L1-values. Values are available from ABB
on request.
Lubrication
On delivery, the motors are pre-lubricated with high
quality grease. The grease grade is stamped on the
lubrication plate fastened to the motor frame. See
page 20 for an example of a lubrication plate.
More information about lubrication and greases can
be found in ABB's High Voltage Process Performance
Manual delivered with the motor.
Motors with relubrication nipples
Motors are lubricated while running and the bearing
system on all high voltage motors has been built so that
a valve disc can be used for lubrication.
The grease outlet opening has closing valves at both
ends that should be opened before greasing and closed
1-2 hours after regreasing. Closing the valves ensures
that the construction is tight and dust or dirt cannot get
inside the bearing.
The table below gives lubrication intervals for different
speeds (according to the L1-principle). The values are
valid for motors using the synthetic base oil mentioned
in ABB’s High Voltage Process Performance Motors
Manual.
For more information, see ABB's High Voltage Process
Performance Motors Manual.
