Negative Hypothesis of Equivalence between Dynamic Magnetic Loss and Eddy Current Loss in Ferrite Grains

Eddy current-based material loss imaging system prototype

Systems that associate positions with eddy current probe readings present inspection data more directly and usefully than the more common impedance plane display. We have economically constructed such an integration of an eddy current testing device with a position feedback device which gives 0.005” achievable resolution. The position and probe readings are fed to a PC and plotted in real-time ...

Eddy current generation enhancement using ferrite for electromagnetic acoustic transduction

examining the relationship between fear of negative evaluation and communication strategies by iranian efl learners

the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...

Modeling of Eddy Current Loss and temperature of the magnets in Permanent magnet Machines

The eddy current loss in the magnets of permanent magnet (PM) motors in a hybrid electric vehicle (HEV) and plug-in HEV is usually not taken into consideration in traditional motor design and analysis. However, due to the high conductivity of the rare-earth magnet, neodymium-iron-boron (NdFeB), and slot/tooth harmonics, there is eddy current loss generated inside the magnets. This loss may not ...
