4. During the test run, check and document the following:
– Check whether it is running smoothly.
– Document the voltage, current and power values. As far as possible, document the
– If this is possible using the available measuring equipment, check the bearing and
– Check the motor for noise or vibrations on the bearings or bearing shields as it runs.
5. In case of uneven running or abnormal noise, switch off the motor. As the motor runs down,
identify the cause.
– If the mechanical operation improves immediately after the motor is switched off, then
