Using Motor Electrical Signature Analysis to Determine the Mechanical Condition of Vane-Axial Fans

PDF Version Also Available for Download.

Description

The purpose of this research was a proof of concept using a fan motor stator as transducer to monitor motor rotor and attached axial fan for mechanical motion. The proof was to determine whether bearing faults and fan imbalances could be detected in vane-axial fans using Motor Electrical Signature Analysis (MESA). The data was statistically analyzed to determine if the MESA systems could distinguish between baseline conditions and discrete fault frequencies for the three test conditions: bearing inner race defect, bearing outer race defect, and fan imbalance. The statistical conclusions for these proofs of concept were that MESA could identify ... continued below

The statistical conclusions for these proofs of concept were that MESA could identify all three faulted conditions.
