变温条件下Energetic磁滞模型参数修正方法
Correction Method of Energetic Hysteresis Model Parameters Under Variable Temperature Conditions
摘要
Abstract
The hysteresis characteristics of ferromagnetic materials are temperature-dependent,thus the performance of iron core equipment is affected by temperature.However,the existing Energetic hysteresis models can not effectively characterize the temperature,resulting in a significant error in the loss calculation.Therefore,the influence of each pa-rameter of the Energetic hysteresis model on the shape of hysteresis loop is firstly studied in this paper.The magnetic properties and temperature dependence of the ferromagnetic material are analyzed.Then,based on the parameter identifi-cation by formula method,the shape eigenvalues of hysteresis loops at different temperatures are extracted.The Curie temperature and critical exponent coefficients are introduced,and the expressions of the shape eigenvalues with respect to temperature are proposed.The expressions of eigenvalues are combined with the identification formulas of various model parameters.Moreover,the model parameter identification method considering temperature characteristics is proposed and a modified Energetic hysteresis model under variable temperature conditions is established.Finally,the hysteresis loop of the material at various temperatures was simulated and compared with multiple sets of measured values while taking the measurement results of the ultimate hysteresis loop of a nanocrystalline alloy as an example,which verified the consist-ence and feasibility of the proposed model.关键词
