No.3（2000）8.Construction of two-dimensional simulation model of a weiss type electromagnet with a general finite element method program
Akihiro MAKINO
The two-dimensional simulation model of a weiss type electromagnet was constructed with a general finite element method program, and the generated magnetic field between the magnetic poles was analyzed when the gap length was 30mm and 10mm.At the gap length of 30mm, the calculated results for linear conditions agreed with the experimental results qualitatively and quantitatively. However, at 10mm, the calculated results for non-linear conditions did not agree with the experimental results quantitatively due to magnetic saturation. In order to remove the influence of the magnetic saturation, it was considered how the magnetic flux was related to the cross section of the magnetic path in the two-dimensional field. As a result of modifying the magnetization curve of the material that was assigned to parts of the yoke, good agreement between the calculated and experimental results is obtained.
