PURPOSE:To provide a magnetic field analyzing method capable of simply analyzing an analytical object such as a rotary machine subjected to skew and made unknown quantity to be not uniform in z direction in a two-dimensional field. CONSTITUTION:At least two or more meshes are prepared (11), non-steady magnetic field analysis (12) is performed regarding at least one unknown quantity as an eddy current by using the two or more prepared meshes, correction calculation (13) for the eddy current obtained as a result of the non-steady magnetic field analysis is executed to calculate an eddy current correction value, and static magnetic field analysis (14) is executed by the use of the eddy current correction value and the two or more meshes. Consequently, the analysis of a rotary machine considering a skew which can not be executed by a conventional method can be simply executed by two-dimensional magnetic field analysis and a magnetic field of a rotary machine subjected to skew such as an induction motor can be numerically calculated. |
