PumpSpectra is the first condition-intelligence product built on SIIP. It turns synchronized electrical signals into physics-gated diagnosis, stable asset state and explainable maintenance intelligence for motors, pumps and the systems they drive.

One evidence chain
Built on the SIIP signal-to-decision architecture, PumpSpectra keeps the complete path traceable. Every conclusion can be followed through context, fault gates and temporal state to the synchronized waveform.
Capture IA, VA, IB, VB, IC, VC and neutral together at 32 kS/s, aligned to a measured grid zero crossing.
Bind the waveform to calibration, meter data, DSP context, motor poles, speed and exact bearing geometry.
Run deterministic C++ FFT and MCSA with physics gates, noise evidence and multi-signal corroboration.
Store the evidence, stabilize state over time and let bounded local AI communicate the approved maintenance action.

Intelligence at the asset
The reference acquisition design routes three voltage and four current paths through RF and anti-alias filtering into the ADE9000. The ESP32 edge node captures calibrated context and synchronized waveforms close to the motor; the CPU/GPU core combines MCSA, full-band FFT, exact bearing geometry, rotor sidebands, pump evidence and power-quality context without reducing the result to a black-box score.

PumpSpectra does more than label a spectrum. It resolves competing signatures, records contamination and preserves the exact features that support—or prevent—a diagnosis.
Broken-bar and eccentricity sidebands are evaluated against refined f0, mechanical speed, slip validity, local noise and phase corroboration.
Competing signatures are compared so rotor unbalance, misalignment and looseness are not reported from the same line without context.
BPFO, BPFI, BSF and FTF are calculated per bearing, with x2/x3 harmonic evidence, confidence and grid-contamination proximity.
Impeller blade count drives blade-pass and fifth-harmonic sideband analysis; load imbalance and low-frequency energy add corroborating evidence.
Current and voltage THD, H3 coupling, phase imbalance and calibrated metering separate supply conditions from asset behavior.
STFT, synchrosqueezed ridges, Haar/db4 wavelets, WPT and joint voltage-current tracks reveal persistence and transients without replacing global FFT gates.
Trust logic
Broken-bar and eccentricity flags require valid f0, poles, speed and slip, plus resolvable sidebands.
Impeller imbalance requires at least two corroborating signals across blade-pass, rotor asymmetry and current imbalance.
When DE and NDE characteristic frequencies are too close, the system reports ambiguity and requests physical inspection.
Two evidence paths
Immediate and historical diagnoses are separate services with separate evidence boundaries. Both use the same deterministic facts; only the historical path adds persistence and temporal context.
CAPTURE MODE
POST /diagnose_fftConsumes a supplied FFT JSON and returns a deterministic, explainable report without reading or writing MongoDB. It is suitable for a live capture or an isolated engineering review.HISTORY MODE
POST /diagnose_historyAnalyzes a selected days, hours or last-N window, measuring fault persistence, health movement, bearing trends, pump evidence and maintenance urgency.Local AI explains these results after the deterministic assessment. It is not permitted to convert a rejected flag into a confirmed fault.
PumpSpectra film
The supplied PumpSpectra footage has been normalized and assembled into one continuous film, with a single player and a seamless visual transition.
