Abstract

To realize the lightweight and fine design requirements of electric locomotives based on actual working conditions, the loss characteristics of three kinds of high-frequency core materials for electric locomotives, ferrite, amorphous alloys, and nanocrystalline materials, were deeply studied in this paper. Firstly, the core material loss characteristics were measured by simulating the actual working state of the locomotive at high frequency. Based on the traditional Steinmetz loss model being optimized and improved and considering the generality of the loss model under different operating frequencies, the loss calculation model was modified by introducing the correction coefficient of the loss model with the change of frequency. Finally, using nanocrystalline core materials as an example, the calculation accuracy of the optimized loss model was verified by direct measurement of the loss characteristics of the core materials, simulation calculation, and physical verification, which proved the feasibility of the optimization scheme of the loss model.
