Different solutions are possible to align motor with load:
- With dial gauge :
- With laser
A laser alignment is highly recommended for speeds > 10000rpm
Warning
Any weight on the shaft (even below maxi bearing force capacity) cannot be supported by
motor bearings: balancing default generates centrifugal force and vibration as a result is
breakdown shaft.
:
The load must be supported by bearings
.
For the fixed through feet motors, after alignment operation, the wobbly foot has to be
steadied before tightening.
4.2.5.
The delivered motor has been controlled and burned in. Nevertheless, it is recommended to start it gradually by
1000-rpm steps with a speed ramp, during 1 minute for each step until the maximum speed. Monitor the bearing
temperature. It must be stabilized. Typical temperatures are 60-70°C.
