Bearing Wear
Progressive spalling and friction in rolling element bearings
Why electrical signals?
Motor current patterns reflect the mechanical condition of every component in the drivetrain. ESA measures these patterns with precision, detecting bearing wear, misalignment, cavitation, and more — before they become catastrophic failures.
Unlike vibration sensors that require physical installation on assets, electrical measurements are taken at the Motor Control Center. One installation point monitors unlimited motors across your facility.
- No asset instrumentation: Measure at the MCC, not the motor
- Physics-based: Motor current patterns reveal drivetrain condition
- Complete coverage: Monitor 100+ motors from a single installation
What ESA Detects
Misalignment
Angular or parallel misalignment in couplings and gearboxes
Cavitation
Vapor bubble collapse in pumps and fluid systems
Blockage
Debris, sediment, or flow obstruction in lines
Belt Degradation
Belt slippage, wear, or tension loss in drive systems
Unbalance
Mass imbalance in rotors causing vibration
