Motor Current Signature Analysis To Detect Faults In Induction Motor Drives - Fundamentals, Data Interpretation, And Industrial Case Histories.

Tutorialpg. 145-156Induction motor drives are the most widely used electrical drive system and typically consume 40 to 50 percent of an industrialized nation’s total generating capacity. In the USA the total generating capacity is approximately 800,000 MW; consequently induction motor drives are major assets in the process and energy industries. Motor current signature analysis (MCSA) is a condition monitoring technique that is now widely used to diagnose problems such as broken rotor bars, abnormal levels of airgap eccentricity, shorted turns in low voltage stator windings, and certain mechanical problems. This tutorial sets out to present the fundamentals on MCSA plus data interpretation and the presentation of industrial case histories
