要約(英語): In the characteristic evaluations of large rotating machines, such as turbine generators, modeling of complex structures, small-sized parts, or local physical behaviors may lead to ill-conditioned and/or a large number of elements. In this study, analysis modeling for evaluation of the electromagnetic behaviors using the nonconforming mesh connection technique is developed by improving the sliding method to simulate movements and the developed method is applied to model the coil end part of a turbine generator. The analysis results are verified by measurements and with the results of a model without the nonconforming mesh connection. Then, the merits and important points regarding the application of the nonconforming mesh connection technique are described.
