Sommario/riassunto |
|
Provides coverage of Motor Current Signature Analysis (MCSA) for cage induction motors This book has 13 chapters and contains a unique database of 50 industrial case histories on theapplication of MCSA to diagnose broken rotor bars or unacceptable levels of airgap eccentricity in cage induction motors with ratings from 127 kW (170 H.P.) to 10,160 kW (13,620 H.P.). There are also unsuccessful case histories which is another unique feature of the book. The case studies also illustrate the effects of mechanical load dynamics downstream of the motor on the interpretation of current signatures. A number of cases are presented where abnormal operation of the driven loadwas diagnosed. Other unique features include: . All case histories are presented in a step-by-step format, with predictions and outcomes supported by current spectra and photographic evidence to confirm a correct orincorrect diagnosis. Chapter 13 presents a critical appraisal of MCSA including successes, failures, and lessons learned via industrial case studies. There are 10 questions at the end of chapters 1 to 12 and answers can be obtained viathe publisher Current Signature Analysis for Condition Monitoring of Cage Induction Motors: Industrial Application and Case Histories serves as a reference for professional engineers, head electricians and technicians working with induction motors. |
