Legg's equation models magnetic material core loss at low flux densities. The equation has three loss components: hysteresis, residual, and eddy current. ==Equation== : where :: ''R''ac is the effective core loss resistance (ohms) :: ''μ'' is the material permeability :: ''L'' is the inductance (henrys) :: ''a'' hysteresis loss coefficient :: ''B''max is the maximum flux density (gauss) :: ''c'' is the residual loss coefficient :: ''f'' is the frequency (hertz) :: ''e'' is the eddy loss coefficient IEC Technical Committee is the modern definition.〔 refers to Publication 401〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Legg's equation」の詳細全文を読む スポンサード リンク
