Approximation of Hysteresis Changes in Electrical Steel Sheets

This paper describes a simple method of approximating hysteresis changes in electrical steel sheets. is based on assumptions that flux density or field strength are sum difference functions describe one curve the limiting loop and certain ‘transient’ component. Appropriate formulas present as those inverse dependencies proposed. An application this approximation requires knowledge measured few minor loops. Algorithms for determining proposed discussed. The correctness was verified through comparison loops with calculated several different excitations magnetic occurring dynamo transformer Additionally, an example discussed paper. recommended numerical calculations distribution
