Balancing plant maintenance costs and activities with the need to achieve production goals is a daily challenge for most maintenance professionals. Since the motor-driven system is often a critical component in this dynamic, this article looks at some best practices to help it achieve those goals and meet customer demands.

This webinar recording covers the various types of trips or faults that occur in applications, as well as some of the causes for these events.

Centrifugal pump failures are most commonly attributed to seal failure, impeller damage and bearing failures. A good understanding of failure modes for seals, impellers and bearings is essential to providing customers with reliable pump repairs.

This book was developed to help electric motor technicians and engineers prevent repeated failures because the root cause of failure was never determined. By using a proven methodology combined with extensive lists of known causes of failures, one can identify the actual cause of failure without being an “industry expert.” In fact, when properly used, this material will polish one’s diagnostic skills that would qualify one as an industry expert.

In a previous article in Plant Engineering ("A systematic approach to AC motor repair," Plant Engineering, April 2015), EASA highlighted the good practices for electrical repair found in ANSI/EASA Standard AR100 Recommended Practice for the Repair of Rotating Electrical Apparatus, and the significant impact they can have on motor efficiency and reliability. But that was only part of the story, because mechanical repairs—and even documentation, cleaning, and inspection—can also markedly affect motor reliability and efficiency.

This technical paper, presented at the 2014 EASA Convention, will help you understand how and why shafts and fasteners fail.

Two of the most important expectations informed end users (customers) have of service centers are consistent best practice repairs and root cause failure analysis (RCFA). Following best practices helps ensure reliable repairs and maintenance of motor efficiency;and RCFA identifies the cause to help prevent a recurrence of the failure. Service centers can meet these expectations by performing repairs in conformance with ANSI/EASA AR100 Recommended Practice for Repair of Rotating Electrical Apparatus; and by providing RCFA in accordance with a proven methodology such as that in the EASA Root Cause Failure Analysis seminar reference manual. Our focus in this article will be on the importance of performing root cause failure analysis.
