要約(英語): The magnetic properties of non-oriented electrical steel sheets under compressive stress were investigated. The iron loss under compressive stress decreases with the increase of Si content. In particular, a 6.5%Si steel sheet shows extremely low iron loss under compressive stress. This decrease is due to the decrease of magnetostriction. To evaluate the effect of magnetostriction on iron loss of the motor, we made IPM motors using 3%Si steel and 6.5%Si steel. In the motor using 3%Si steel, the motor loss is increased after the heat shrinking. On the contrary, in the motor using 6.5%Si steel, the motor loss showed little change after the heat shrinking.
