Simulation and statistical approaches on electrical steel’s magnetic behaviour under unidirectional single sheet tester

Evaluation of magnetic properties of electrical steel is vital in improving the quality of electrical machinery since it is used as magnetic cores for transformers, motors and generators. A double yoke single sheet tester (SST) was modeled using two identical C-cores wound with copper wires at limb...
