Leadership Matters – 35 Years From My View

What does 35 years of practicing engineering get you? Thousands of projects (and some gray hair). EME, founded by Don Reilly and me, is celebrating its 35th year of service to our many clients. Over those years we performed over 3,000 projects varying from a few hours of consulting to major engineering efforts requiring detailed analysis. [...]

The Quarterly Engineering Problem – An Actual Case

EME was contracted to determine how high some large motors could be uprated. We determined an uprating of over 50% could be achieved provided the motors be rewound with minimum insulation thickness thereby maximizing the copper while at the same time reducing the thermal impediment for getting heat out of the coils. The manufacturer [...]

Passing The Baton by Alan J. Spisak

Passing The Baton – Alan J. Spisak, P.E., President/CEO How do you fill the shoes of a legend? As a young engineer fresh out of college, I joined EME.  Like many individuals transitioning from the role of an engineering student to that of a professional, I wasn’t certain what ‘being an engineer’ meant.  I had interned [...]

Generator Matters – When a Band-aide Won’t Work

End-Turn and Phase Lead Vibration Generator end baskets on large turbine generators present unique design challenges for generator manufactures and service organizations. End baskets are comprised of individual end turns, which are integral to the end basket support structure through their arch binding with other structural components.  This electrical and structural system made of [...]

Leadership Matters – Are your Suppliers Listening?

Customer Collaboration – In the practice of engineering we are fundamentally problem solvers.  Our education, training and vitally our experience, are all brought to bear when helping a customer to resolve or understand an issue.  When presented with an issue we quickly move into “Given, Find, Assumptions, Solutions” mode; transitioning as quickly as possible to [...]

The Quarterly Engineering Problem – An Actual Case

Many large hydro-generators have baffle plates on the rotor spider.  The baffle plates induce and control airflow in the unit to cool the rotor rim, pole windings and primarily the stator.  EME recently investigated a unit with a rotor of approximately 300 inches in diameter, which had 8 spider arms, and a span between [...]

Fuji GTLR Brushless Exciter – Will it Survive?

Recently a generator experienced an overspeed (approximately 4,739 rpm) event. Typically for a 60Hz generator the rotor is designed for stresses at 20% (<4,320) overspeed.  As a result, EME was asked to evaluate portions of the generator rotor (radial studs, retaining rings, forging, & wedges) to determine the stresses that existed at 4,739 rpm and [...]
