Influence of the geometric parameters of a vertical rotational single-sheet tester on sample field homogeneity

Résumé

Purpose The horizontal rotational single-sheet tester (RSST) suffers from weaknesses such as the reduced size of test samples, measurement disturbances due to magnetic flux leakage and nonhomogeneity of field in the measurement area. Although the vertical RSST allows to overcome the first two aforementioned drawbacks, the heterogeneity of the field in the test sample remains an issue. In addition, there is still a lack of device standardization to ensure test repeatability, as already is well established with the Epstein frame. This paper aims to investigate the influence of several parameters on the field homogeneity in the test sample. Design/methodology/approach A fully 3D finite element model of a vertical RSST is developed and used to perform a sensibility study on several geometrical parameters. Findings The influence of several parameters on the field homogeneity in the test sample, such as the geometrical dimensions of the yokes, the presence or not of holes drilled inside the test sample for B-coil placement as well as the size of the H-coils and B-coils, is addressed. Originality/value It is expected that this study will contribute to the optimization and standardization vertical RSSTs.
