Abstract

This paper describes the characteristics analysis of induction motors by considering stress caused by shrink fitting of stator cores. The electromagnetic field and stress analyses are combined in order to take into account the deterioration of permeability and the increase in core loss. The calculated results are compared with the result of experiments in order to confirm the validity of the combined analysis. It is revealed that the efficiency of the induction motor decreases by several percent because of increases in both the core loss and the copper loss by the shrink fitting.
