Summary on Grant Application Form |
|
AC magentic properties of non-oriented electrical steels will be measured in a purpose designed single sheet tester over a range of magnetising frequencies and waveforms. Losses will be analysed into components including anomalous loss in a form suitable for embedding into FEA programmes for predicting electrical machine losses. Likewise, algorithms of permeability - magnetic field - loss data will be produced in a form suitable for the machine performance prediction models. Vector hysteresis models will be investigated and the procedure for identifying the model parameter sfrom the set of experimental measurements defined. The vector hysteresis model will be integrated into a 3D finite element package. Predictions will be compared with measurements. The FE predictions will account for classical and anomalous losses.Dynamic magnetic domain studies will be carried out to help develop a better understanding of the mechanisms causing anomalous loss. An attempt will be made to measure internal flux distribution and effects of non-uniform material permeability. Anomalous loss will be directly measured in a stator lamination to provide data to assess the accuracy of computer models in analysing stray losses.
