| Outline of Final Research Achievements |
In order to reduce the iron loss of electrical steel for motors, we have to control the magnetic easy axes which orient to thick-direction of the electrical steels due to random orientation of crystal grains. An in-plane eddy current loss associated with thick-direction change of magnetic flux will be reduced when the thick-direction components of the magnetization can be turned toward in-plane of the electrical steels. Therefore, to obtain a basic relation, we investigated magnetic properties of electrical steels under uniform in-plane stress.As a result, it is clearly observed that the magnetization increases with tensile stress, and decreases with compressive stress. It is expected that the magnetizations of thick-direction were rotated to in-plane by applying tensile stress. These results shows the proposed method can reduce the iron loss of the electrical steels.
