- For mechanical failures or asset-specific failure modes (e.g., cavitation in a pump) unique vibrations are generated that travel throughout the drivetrain and reach the motor where they affect the air gap between the rotor and the stator. These vibrations cause variations in the motor’s magnetic field that are visible in current and voltage signals. Then, by translating these measurements into a frequency spectrum, we can compare real-time data to a baseline and identify deviations corresponding to specific failure modes.
- For electrical failures, SAM4 captures the relevant variations in the current and voltage data and can identify electrical unbalances, harmonic distortion, and more.
