Core Tester Iron Losses Segregation by Finite Element Modeling

A new designed core tester and its feeding and control devices are presented in this paper. With this workbench, mounted single phase induction motor stators can be magnetically fed with controlled induction waveforms in order to evaluate their quality in the industrial environment. As the measured data involves the machine stator as well as the core of the testing apparatus, Finite Element and iron losses modeling are employed in this paper in order to distinguish the losses of the stator under test and the losses of measurement device itself. Therefore, the main goals of this paper are to propose a new tester design as well as a numerical way allowing the separation of the losses in the stator under test and the losses inherent to the tester itself.
