The motor warns you
months before it breaks.

DeepMaint measures voltage and current at the control cabinet and finds the fault while it is still incipient. No motor teardown, no production stop, no model to train.

HOW IT WORKS

Three steps from the cabinet to your screen

01

Measured at the cabinet

Six Hall effect current sensors and three voltage fuses on DIN rail, next to the rest of the motor switchgear. Voltage measured directly up to 1 kV; above that, from the transformer secondary. Converters of 16 to 24 bits.

02

Electrical signature analyzed

Every fault injects its own harmonics into voltage and current. A single capture holds up to a million possible harmonics. The UPV patented algorithm pinpoints the ones that reveal a fault and tracks how they grow.

03

Read in the web app

Motor health, power, efficiency and power quality, with indicators refreshed on the server every 2.5 minutes. No prior training: the indicators are physics based, explainable and comparable across motors.

REAL CASES

What the customer found inside the motor

Three detections on machines in production, with the indicator moving weeks or months before the failure.

230 HP MOTOR

Rotor end ring wear

The rotor asymmetry indicator rose steadily from February to September. After more than six months of growth, the customer pulled the motor out of the well.

Severely worn end ring. Cheap to repair; left alone, the debris would have damaged the stator winding.
PUMP IN SERVICE

Stator insulation failure

The stator condition indicator started climbing with the motor running. One month after the first alarm the customer sent it to the repair shop.

Phase to ground resistance had dropped from 500 to 200 MΩ. Caught without partial discharge testing and without stopping the process.
MOTOR IN OPERATION

Shaft fracture

The eccentricity indicator grew clearly from late September. The customer chose to keep the motor running for twenty more days.

The indicator dropped sharply: the shaft had snapped and the rotor spun free. The alarm had been on for three weeks.
CAPABILITIES

One device, four jobs

Everything comes from the same voltage and current measurement taken at the cabinet.

Predictive maintenance

Detects incipient faults in the motor, the drive and the load. It is the only device based on voltage and current during normal operation able to see short circuits between a few stator turns, one of the most critical and fastest evolving faults.

Power measurement

Active, reactive and apparent power and power factor per IEEE 1459, traced with over 20,000 points per second. Captures fast transients such as a direct on line startup, with peaks of 3 to 10 times rated power.

Efficiency

Traces the motor efficiency curve across the speed range and places the current operating point on it. If the load curve is known, as with a hydraulic pump, the whole set is optimized and not just the motor.

Power quality

Symmetrical components and imbalance, voltage and current THD, TDD, crest factor, sags, swells and interruptions. Each indicator computed per its standard: IEEE 1159, IEC 61000-4-7.

WHERE IT COMES FROM

Twelve years of research at the Universitat Politècnica de València

UPV is the leading engineering university in Spain according to the Shanghai ranking and the national leader in patents: 44 filed and 18 licences issued in 2024 alone. Its Ideas Institute has spun out more than 800 companies. DeepMaint is one of them, already running at water sector companies, with deployments planned in energy and oil & gas.

RATING Validated from a few kW up to 2 MW
VOLTAGE From 400 V to 6.6 kV, low and medium voltage
SLIP From 0.5 % to 6 %, 1 to 5 pole pairs
INSTALLATION DIN rail, Ethernet or WiFi, router included

Why it replaces the maintenance round

Genuinely non invasive

Installed at the electrical cabinet and measuring during normal operation. Nothing is dismantled and the production process is untouched.

Reaches inaccessible motors

Submersible pumps in aquifers 50 to 500 metres down, or motors in hazardous atmospheres, monitored from surface measurements alone.

No training, no history needed

Indicators are physics based and predefined. No model to feed for months and no fault history required for the asset.

One avoided stoppage pays for it

The cost of an unplanned stoppage and a multi component repair far exceeds fixing a single incipient fault you already located.

BUILT FOR
Water and pumping
Process industry
Energy
Oil & Gas

One unplanned stoppage costs more than the whole system.

We send each detection case as we publish it: which indicator moved, how long before the failure, and what showed up inside the motor. No filler, no sales team behind it.
