● If mechanical operation does not improve immediately after switching the motor off, the
cause is mechanical, e.g. imbalance of electrical machines, etc.
● If the motor is running perfectly, switch on the cooling equipment.
● Observe the motor for a while during no-load operation.
NOTICE
Overheating during test runs without water cooling
The motor can overheat without water cooling. Reduce the ON duration accordingly if the
water cooler is not to be operated during a test run.
● If it runs perfectly, connect a load.
– Check whether it is running smoothly.
– Record the voltage, current, and power values.
– As far as possible, record the corresponding values of the driven machine.
– Monitor and record the temperatures of the bearings, windings, and so on until the
system reaches a steady state.
