Abstract Thickness and frequency dependence of core loss in the non-oriented electrical steel containing 3.1wt% Si was investigated in the range of 0.20-0.70㎜ in thickness and 50-400㎐ in frequency. As the specimen becomes thinner, the eddy current loss decreases whereas the hysteresis loss increases. Due to this phenomenon, there exists a thickness where the minimum core losss can be otained at a given frequency. The portion of eddy current loss in the core loss increases with frequency, and this tendency becomes more prominent in thicker specimen. The respective portions of eddy current and hysteresis loss are found to be dependent on specimen thickness and test frequency.
