Fitting pinions, pulleys and couplings.
These should be bored to our standard limits and fitted on
the shaft with a screwing motion. Attention must be paid
to correct guarding of all moving parts.
NOTICE
Tapping of fittings onto the FC motor shaft, with a
hammer or mallet, causes bearing damage. This results
in an increase in bearing noise and a significant
reduction in bearing life.
NOTICE
Max. the B14 flange, see
.
2.2.6 Alignment
When the application calls for direct coupling, the shafts
must be correctly aligned in all three planes. Bad
alignment can be a major source of noise and vibration.
Allowance must be made for shaft endfloat and thermal
expansion in both axial and vertical planes. It is preferable
to use flexible drive couplings.

2.2.8 Maintenance
Routine cleaning of the FC motor
Remove the fan cover and ensure that all air inlet holes
are completely free. Clean any dirt and obstructions from
behind the fan and along the ribs of the frame, and
between the motor and inverter part.
Periodic maintenance of motor part
1.
Remove the inverter part, the fan cover and the
fan which is keyed to the shaft extension. Loosen
and remove bearing cover screws and endshield
bolts/studs. The endshields should then be eased
off their spigots.
2.
The rotor can now be carefully withdrawn from
the stator, taking care not to damage the stator
bore and both stator and rotor windings.
3.
Having dismantled the motor, maintenance can
be carried out to remove all dirt. For this
purpose, the use of an air line supplying dry
compressed air under comparatively low pressure
is best, as a high velocity air-stream can force dirt
