Time‐averaged and instantaneous magnetic loss characteristics of different products of electrical steel for frequencies of 16 2/3 Hz up to 500 Hz

Traditionally, products of electrical SiFe steel are focussed on applications for frequencies 50–Hz. However, the recent developments electric drive systems yielded a strong extension range from f = 16 2/3 Hz up to ca. 500 Hz. In spite high industrial relevance, literature offers corresponding data material’s magnetic energy losses in very rare ways. This paper reports first comparative, multi-parametric study eight different that comprise non-oriented steels (NO), grain-oriented (GO) and scribed (SGO). Consistently at IEC-standardized samples, they were analysed whole frequency was split into low (LF) medium (MF), with 80 as border. Data is presented time-averaged total P, hysteresis PH eddy current PE. LF proved be governed by MF rather PE, however, variations. Further, instantaneous magnetization power functions p(φ) determined basic insights involved temporal dissipation. GO-steels profiles close rectified co-sinus can fully attributed dissipative losses. On other hand, p(t) NO-steels SGO-steels prove include negative segments reflect potential power, course alignments atomic moments instants induction. Examples relevance accumulated production technology, product categorization, failure tracing conversion.
