V-belt Fault Detection using Motor Current Signature Analysis in Centrifugal Fan System

Abstract

Asynchronous drives are widely used in many industrial applications because of their low cost, high performance and robustness. However, faulty operations may appear during the lifetime of the system. This paper deals with the use of motor current signature analysis (MCSA) as a diagnostic technique for the influence of V-belt drive faults on three-phase induction motors. For this purpose, we create faults on the belt such as axial misalignment and side-cut-off fault.
