A new heat resistant impregnating resin has been developed for two kinds of traction motors: dc motor and variable-voltage, variable-frequency (VVVF) inverter-type induction motor. Motorette test of dc motor under more severe conditions than IEEE No. 304 indicates that the insulation system satisfies the thermal class 220°. Motorette test on mica insulation for the induction motor according to IEEE No. 275 also demonstrated conformance with thermal class 220. The insulation system has been successfully applied to the VVVF inverter-type induction motors.

The use of structural adhesives has become wide spread in many areas of manufacturing. This paper will discuss one specific application of structural adhesives to bond transformer tank covers. The procedure used in the evaluation and the acquired test data and conclusions will be presented. In addition other applications of structural adhesives for transformers, both in use and under investigation will be discussed.

Prediction of the mechanical properties (modulus and strength) of a mica reinforced epoxy composite has been examined. Influence of mica platelet volume fraction and its aspect ratio (length to thickness ratio) on the predictability of the mechanical properties has been evaluated; theoretical results are compared against the experimental values. The role of failure modes, platelet pull-out and fracture, in controlling the mechanical properties has been studied using scanning electron microscopy. Theoretical upper and lower limits on the flexural strength of the composite have been proposed.

Engineering Services, in the specialized niche of Electrical Engineering entitled Electromagnetic Compatibility (EMC), are offered in the three general areas of Design Consulting, Laboratory Testing, and Theoretical Education. These three service areas are offered both by Independent Corporations and by In-House Resource Groups.

The influence of environmental contamination on the flashover voltage of three polymer insulating materials nomely polystrene, polyvinyl chloride and polymethylmethacrylate is studied. The insulation was subjected to direct voltage stresses under inhomogeneous field conditions (roa-plate electrode system). Results are presented and discussed in this paper. The flashover voltage of polymer insulating materials was found to decrease with increasing the contaminate solution, moisture absorption and ambient temperature. The polarity of the applied voltage was also found to affect the magnitude of the flashover voltage. The variation of thickness of the polymer insulating materials on the surface flashover voltage is also discussed.

Statistical Process Control (SPC) must be viewed as a “way of life” and not just another quick-fix pill. Success takes time. Also, quality must be built around the concept of survival and blended in with other pertinent subjects, such as product applications, etc. SPC topics such as capability, control charts, and pareto analysis should be made as simple and understandable as possible. Use of video tapes is especially helpful. Finally, and most importantly, stress the fact that statistics do not control quality, people do!

The work of the NEMA Magnet Wire Technical Committee has not yet yielded single definitive tests for windability and formability and, realistically, may never do so. The Committee is, however, investigating several test procedures that show some promise of being able to provide quantitative evaluation of the desired properties.
