Maximizing Electric Motor Efficiency

How to get the most from your rotating machines BY STEPHEN MANSFIELD, TechnoWise Inc. An area of great interest is improving the efficiency of electrical devices. More electric motor efficiency means less electrical energy consumed and thus less impact to the environment. By far, the largest...

Monitoring Stator Winding Deterioration

The importance of partial discharge testing in electric motors BY VICKI WARREN, Iris Power LLP Comparing partial discharge (PD) results obtained from a single machine is a valuable tool that enables companies to observe the gradual deterioration of a machine stator winding. Proper monitoring of...

Enhance Performance with VFD Technology

Energy savings for pumping applications BY TOM NEUBERGER & STEVEN WESTON, Eaton In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars and aluminum foil. Because VFD improved process...

Overload Protection for Electric Motors

Thermal images are an easy way to identify apparent temperature differences in industrial three-phase electrical circuits, compared to their normal operating conditions. By inspecting the thermal differences of all three phases side-by-side, technicians can quickly spot performance anomalies on...

Understanding Short Circuit Motor Contribution

A back to basics approach BY DARRELL BROUSSARD, GE Industrial Solutions An electric motor’s contribution is the current generated by a motor or motors during a short circuit condition. It represents a small but important value that is needed to determine the maximum short circuit current...

Reviewing Electric Motor Reliability Research

What did the studies really say—then and now? BY HOWARD PENROSE, Ph.D., CMRP One of the most frequently quoted studies related to electric motor reliability is a 1983 Electric Power Research Institute (EPRI) project, entitled “Assessment of the Reliability of Motors in Utility Applications:...

Improving Motor Maintenance Practices

Useful approaches to building an effective operation and maintenance program

BY IAN CULBERT AND VICKI WARREN, Iris Power Engineering

The pressures to be more competitive and cost-effective in today’s deregulated market have driven plants to reduce resources by making more informed, condition-based decisions regarding equipment maintenance activities. These decisions go beyond the traditional technical specifications and acceptance criteria that were used when plants where designed and manufactured.

Motor maintenance programs must balance safety and economic...
