Testing a production motor by comparing with a reference motor
1) Select the Motor ID for the production motor to be tested. Ensure that it uses the
same Test ID as the reference motor. If the subject motor has not been entered into
the database, add it via the
Data
tab
Nameplate
view, ensuring that it is the same
type of motor as the reference. Then ensure that the proper Test ID is assigned.
2) You can confirm that the selected Test ID has a waveform attached by viewing the
Surge Test
setup window. The
Test-Ref EAR (%)
box will be checked and a
Display
Ref
button will be visible.
3) Click on the
Display Ref
button and the reference waveform will be displayed.

Display reference button.
4) Click
Close
to return to the
Main
window,
Tests
tab.
5) Click the
Run Auto Test
button to begin the test.
6) The software will automatically run through the resistance and DC tests, and if the
motor passes all other tests, it will automatically continue with the Surge test.
7) If the software detects a reference test, it will calculate the Error Area Ratio (EAR) at
the end of the Surge test. The EAR is calculated between leads of the motor under
test and compared to the reference motor test results. The software will then
compare the EAR values with the tolerances entered in the Surge test parameters. If
the EAR values are within tolerance, the motor passes. Conversely, if an EAR value is
outside the tolerance, the motor fails. After the test has been performed and saved,
surge waveforms can be examined via the
Data
tab
Surge
view.
