Zusammenfassung:To design a core that has high feasibility and improves characteristics of an electric apparatus.SOLUTION: A core design processing device 100 acquires conditions data including a basic shape 400 of a core to be designed, magnetic characteristics data 500 of a high magnetic permeability section, and magnetic characteristics data 600 of a low magnetic permeability section to determine an arrangement of the high magnetic permeability section and the low magnetic permeability section in the core to be designed based on the acquired conditions data. The core design processing device 100 sets, in order to determine an arrangement of the high magnetic permeability section and the low magnetic permeability section in the core to be designed, a temporary arrangement of the high magnetic permeability section and the low magnetic permeability section in the core to be designed, performs an electromagnetic field analysis relative to a model of an electric apparatus including a core having the set temporary arrangement to determine an arrangement of the high magnetic permeability section and the low magnetic permeability section in the core to be designed based on characteristics of the model of the electric apparatus obtained by the electromagnetic field analysis and the temporary arrangement of the high magnetic permeability section and the low magnetic permeability section in the core to be designed.SELECTED DRAWING: Figure 1 【課題】 実現性が高く電気機器の特性を向上させるコアを設計する。【解決手段】 コア設計用処理装置100は、設計対象のコアの基本形状400、高透磁率部の磁気特性データ500、および低透磁率部の磁気特性データ600を含む条件データを取得し、取得した条件データに基づいて、設計対象のコアにおける高透磁率部および低透磁率部の配置を決定する。コア設計用処理装置100は、設計対象のコアにおける高透磁率部および低透磁率部の配置を決定するために、設計対象のコアにおける高透磁率部および低透磁率部の仮配置を設定し、設定した仮配置を有するコアを含む電気機器のモデルに対する電磁界解析し、電磁界解析により得られた電気機器のモデルの特性と、設計対象のコアにおける高透磁率部および低透磁率部の仮配置とに基づいて、設計対象のコアにおける高透磁率部および低透磁率部の配置を決定する。【選択図】 図1
