Abstract

We performed the stress analysis of a SPM motor core with the shrink fitting, and calculated the iron loss by FEM using the B-H curve and iron loss measured under a compressive stress. We examined the effect of shrink fitting on iron loss of an actual motor and the validity of the estimation of the iron loss by FEM analysis using the measured properties affected by the stress. It is shown that the magnetic properties under the compressive stress should be considered for the precise estimation of the iron loss in a motor with the shrink fitting.
