The B-H curve and iron loss of electrical steel sheet are essential data for predicting electric motor characteristics. Typically, the
Epstein frame test is adopted widely, to acquire these magnetic properties. However, for the rotating electrical machines with small
geometry, the ring core test can be preferred. In this paper, B-H curve and iron loss of non-oriented electrical steel sheet are measured
by Epstein frame test and ring core test. Each result applied in finite element analysis (FEA) of the fabricated electric motor.
Furthermore, using these FEA results and d-q equivalent circuit, prediction of the electric motor performance is made. As the
experimental verification, the electric motor tests are done under no-load and load condition.
