Winding Vibration & Magnetic Wedges Detection

In a 24/7 critical compressor, Enging detected an abnormally high spectral component at 896 Hz, causing a high-frequency ripple in the motor phase currents.
By validating the motor's internal design with the client, it was confirmed that this frequency was linked to internal stator winding vibration — a fault that often goes unnoticed until severe damage occurs.

With early detection powered by Electric Signature Analysis (ESA), the issue was identified before it escalated, ensuring reliability and continuous operation.
