Abstract
Abstract The development of high-efficiency, low-loss motors is required for industrial and automotive applications. We propose that motors with high efficiency and low loss can be developed by controlling the vector magnetic properties of non-oriented electrical steel sheets by applying stress. Therefore, it is necessary to examine not only the magnitude of the magnetic field strength but also the spatial phase difference between the B and H vectors under stress. In this paper, we present a measurement system that we developed to clarify the relationship between stress and vector magnetic properties.
