Abstract :
Electrical steel is used in an electrical motor or a transformer because it has superior magnetic property such as magnetizing characteristics and low iron losses. Numerical calculation such as finite element method is useful to evaluate and design the motor characteristics of electrical torque or iron losses. In this paper, the combined analysis of electromagnetic field and mechanical stress is applied to the shrink fit and the stamping effect phenomena to estimate the iron loss in comparison with the experimental data.
