Trial run
If the period between installation and commissioning is expected to be fairly long, make sure
that water-cooled machines undergo a test run without water cooling.
Procedure
● Start up the motor without a load, temporarily. Check the direction of rotation at this point.
● As the motor is coasting down, check the mechanical operation for noise and vibration at
the bearings and bearing shields.
● Where the motor is running without any mechanical problems, switch it back on again.
Continue to the maximum speed allowed (according to the rating plate).
● In case of uneven running or abnormal noise, switch off the machine. Determine the cause
as it coasts.
● If the mechanical operation improves immediately after the motor is switched off, the cause
is magnetic or electrical.
