ESA requires certain motor nameplate information to be input into InsightCM in order for the analysis and calculations to take place:
-
Load
-
Load Unit (HP or KW)
-
Nominal Frequency (50 or 60 Hz)
-
Synchronous speed (RPM)
-
Full load speed (RPM)
-
Rated volts (Volts)
-
Full load amps (Amps)
-
Service Factor
-
Power Factor
-
Full Load Efficiency
These are optional Nameplate/ESA Property fields:
-
Efficiency at 75% Load
-
Efficiency at 50% Load
-
Efficiency at 25% Load
-
Number of Stator Slots
-
Number of Pump Vanes / Fan Blades
-
Number of Rotor Bars
The data above can be found in a number of different locations:
-
Motor Nameplates
-
Spare Motor Nameplate
-
Motor/Pump Manuals
-
Previous Test Reports
-
CBM/PdM Databases/Reports
-
Relay/Protection Documents
-
Etc.

Use the phasor diagram to ensure that the three phases of current and voltage are in the proper relationship. With induction motors, current will lag voltage. Oftentimes during installation, phases are swapped or the polarity is flipped. Both of those conditions can be corrected in InsightCM without needing to go back into the field to make the change.
Below is an example of an installation where the current sensors were flipped in the field. Notice the B and C phasors are 180 degrees out of phase with their voltage phases. This can be corrected by checking the reverse polarity box in the asset configuration page and pushing the new configuration.
Below is the phasor diagram after the current polarity reversal. Notice each current phase lags its associated voltage phase:
