HOW IT WORKS
Three steps.
One report.
Current and voltage carry information about the motor and the load it drives. AMTPro captures them at the cabinet and turns them into a condition report your team can act on.
Capture at steady operation.
Test while speed and load are stable, not during start-up or shutdown. Enter the nameplate, and the bearing model if you want bearing-specific results.
Read the report.

Detected issues
Loose FoundationGearbox FaultCurrent UnbalanceTHD Voltage WarningMotor Underloaded
Electrical performance
Current unbalance5.8%Warning
- Reason
- The current unbalance is high while the corresponding voltage unbalance is very low (<1%), indicating the source of the imbalance is within the motor itself.
- Result
- This condition generates excessive heat in the windings due to negative sequence currents, accelerating insulation degradation.
- Recommendation
- Perform offline winding tests (Megger/Resistance) at the earliest opportunity to confirm the health of the stator insulation and windings.
THD voltage5.61%Warning
- Reason
- The presence of non-linear loads on the electrical network is introducing harmonic distortion into the power supply.
- Result
- High voltage distortion can cause additional heating in the motor, interfere with sensitive electronic equipment, and reduce overall system efficiency.
- Recommendation
- Investigate the electrical distribution system for sources of harmonics. Check the functionality of any existing harmonic filters or consider installing line chokes to mitigate distortion.
Motor load27.23%Underloaded
- Reason
- The motor is operating significantly below its rated capacity. This may be due to process requirements being lower than the motor's design capability or intentional oversizing.
- Result
- Operating at such a low load reduces motor efficiency and power factor, leading to increased operational costs.
- Recommendation
- Verify current process requirements to determine if the motor is oversized for the application.
Voltage unbalance0.39%Normal
Immediate actions
- Check the tightness of all accessible foundation and motor anchor bolts, torquing to specification if necessary.
- Investigate the source of the high THD on the voltage supply. Identify and address non-linear loads on the same circuit.
Conclusion
A loose foundation is the likely primary driver and a contributing factor to the gearbox fault. The high current unbalance points to the motor itself and should be confirmed with offline testing.
IN THE FIELD
One blower test.
Three findings on the machine.
A belt-driven process blower (415 V, 95 A, on a VFD) was tested with AMTPro at its drive cabinet. The report put three categories in Caution. The site team then checked each one on the machine.
REPORT CATEGORY → FOUND ON SITE
A foundation bolt on the motor and blower base came out by hand, without a spanner.
The pulleys were out of alignment.
The belt was worn.
Bearing, rotor, stator and other stayed below Caution.
MORE FROM THE FIELD
ELECTRICAL · SUPPLY
A hot connection
on one phase.
On a 250 HP blower motor (480 V), the AMTPro power page flagged phase currents above the nominal tolerance and called for a hot-spot check. The thermal scan found one phase connection at 216 °C. The neighbouring phase read 53 °C.
BEARINGS
Bearing alert.
Damage confirmed.
A routine AMTPro test put Bearing in the High zone, together with unbalance/misalignment and transmission element. When the equipment was opened, the bearing had failed: the balls were badly damaged.
Photos and reports from customer sites, shared by Artesis partners. Findings are shown the way the AMTPro report shows them: by category, then confirmed on the machine.
WHAT IT FINDS
Seven categories.
What to inspect for each.
The AMTPro report shows loose foundation and components, unbalance and misalignment, transmission and driven equipment, bearing, rotor, stator and other. Results are reported by category, with the check that confirms the cause.
ELECTRICAL
Stator, rotor
and supply.
Stator and rotor indications at category level, plus external electrical conditions: supply and connection problems upstream of the motor. The report says what to check first, starting with terminals and supply quality.
MECHANICAL
Foundation, alignment
and coupling.
Loose foundation or components, unbalance, misalignment and coupling condition. The report says what to check: bolts and soft foot, alignment and balance.
BEARINGS
Outer race, inner race,
ball and cage.
With the bearing model entered, AMTPro marks the defect frequencies of each bearing element. The Pin-Point tool puts the markers on the spectrum for the analyst.
DRIVEN EQUIPMENT
Belts, gears,
fans and pumps.
Belt condition, gear mesh and blade or vane pass on single-stage machines such as fans, pumps and conveyors. Enter the sheave, gear or vane details to use them.
POWER & ENERGY
Supply, load
and efficiency.
Voltage and current imbalance, harmonic distortion, load, power factor and energy use. AMTPro also suggests the motor size and efficiency class that fit the duty.

AR-PLUG · ONLINE TESTING
Test without
stopping the motor.
The AR-Plug extends AMTPro for online testing. It connects safely to transformers and voltage points while the motor keeps running, so critical motors can be tested on a round without a shutdown.
- Connect to transformers and voltage points while the motor runs.
- The contact design prevents open circuits during testing.
- The same AMTPro test and report as a standard connection.
BEFORE YOU TEST
Test requirements
and coverage.
What a valid test needs on site, and what a portable test covers.
WHAT YOU NEED ON SITE
- Access to three-phase current and voltage at the motor control cabinet.
- Direct connection up to 690 V line to line; PTs above that.
- Motor stopped while connecting, unless the AR-Plug is fitted.
- Stable speed and load during the capture.
- Nameplate data. Bearing model, belt, gear or vane details for the checks that use them.
COVERAGE
- Results are point-in-time, for the assets you test. Trends build from one test to the next.
- It does not watch the motor between tests, so supply or load events that occur between tests are not captured.
- Stator coverage is narrower than e-MCM, which learns each motor's model continuously.
- Pump performance analysis (flow, head, efficiency, operating zone) runs on e-MCM with OmniSight.
AMTPro AND e-MCM
Test with AMTPro. Watch with e-MCM.
Use AMTPro across the plant to find where attention is needed, and e-MCM with OmniSight on the assets that need continuous watch.
