摘要: The magnetic properties of nonoriented electrical steel sheets under compressive stress were investigated. Iron loss decreases with an increase Si content. In particular, a 6.5% sheet shows extremely low deterioration ratio iron stress. Furthermore, the 6.7% was negative. These results explained well by magnetostriction. decrease To evaluate effect magnetostriction on in motor, interior permanent magnet motors made using 3.0%, 6.5%, and sheets. motor 3.0% steel, increased after heat shrinking. On contrary, showed little change shrinking decreased
