Influence of Different Cutting Techniques on the Magnetic Characteristics of Electrical Steels Determined by a Permeameter

Research output: Contribution to journalArticleResearchpeer-review


In this paper, the influence of three different cutting techniques, in particular mechanical cutting, solid-state laser cutting, and carbon dioxide laser cutting, on the quasi-static hysteresis curves of three different materials, commonly used with electric machines, is investigated. Furthermore, the additional effects of sample size and cutting direction are discussed. In contrast to the commonly used Epstein frame or ring sample tests, the examinations are carried out with a permeameter. A significantly different shape of the hysteresis curves of the small laser-cut in contrast to the mechanically cut samples is found. Furthermore, for some samples a point of intersection is observed above which the magnetic behavior of laser-cut samples is better than that of the mechanically cut samples.
