The magnetic permeability properties of electrical steels are especially sensitive to mechanical stress. During the manufacturing processes required to form a core, steel is subjected to stresses, grain structure is damaged, and the core loss increases. For wound or formed cores, where there is a substantial amount of both plastic and elastic strain, the [...]
