What we monitor
Equipment monitored by SAM4
SAM4 uses current and voltage measurements at the motor control cabinet to monitor motors and driven equipment. Explore each asset type for detection examples, operating requirements and limits.

Submerged Sewage Pumps
Transmissions
Where SAM4 applies, and where it doesn't.
SAM4 monitors
- AC induction motors (any manufacturer)
- Low voltage (<690V) and medium/high voltage (>690V)
- Direct online, soft starter, and VFD-driven motors
- Motors from 1 kW upward
- Motors operating at as little as 5% of rated load
Current scope boundaries
- DC motors and servo motors are not supported
- 2-pole synchronous motors require technical assessment
- Assets operating less than 10 hours per month lack sufficient data
- Duty cycles under 5 minutes provide insufficient signal
- For VFD-driven motors, power quality upstream of the VFD is not visible to SAM4.
- Partial discharge detection not available for MV assets
Asset-specific boundaries are covered on each asset page.
Measured across 2,087 reviewed events.
95.5%
Recall on confirmed fault events. 1,372 of 1,437 fault events detected before breakdown.
2.1%
30 false alerts across 1,402 customer-facing detected and false-alert outcomes.
7,000+
Monitored assets across 80+ customers, five continents.
4–8 wk
Typical detection lead time before vibration-detectable stage.
Calculated from 2,087 reviewed events on the monitored fleet, 1 May 2025 to 1 May 2026. Recall is measured across 1,437 confirmed fault events; the false-alert rate across 1,402 customer-facing detected and false-alert outcomes. Inconclusive, not applicable, and unresolved outcomes are excluded from the metric denominators. Reviewed quarterly. Methodology: SAM4 alert issued, field verification by customer or Samotics service engineer, outcome logged.
Michael Horner, Yorkshire Water
"System works very well, support is also very good which is fundamental in making further improvements. Critical in our monitoring of hard to reach assets such as submersible pumps."
John McCrystal, DuPont
"We invested heavily in condition-based maintenance — vibration, oil analysis, airflow, the lot. But those approaches can still be snapshots. SAM4 added continuous visibility."
