Abstract

This paper presents the structural analysis of concentrated flux type motor for vehicle. The maximum stressoccurred at non-magnetic region therefore structural analysis of non-magnetic material region is necessary for design ofconcentrated flux type motor. The maximum stress can be reduced by applying more layers of joints. Stress can bereduced to 70% of 1 layer model as 2 layers are applied. Therefore, safety factor can be increased without change ofmaterial.
