摘要

A new grain-oriented electrical steel sheet, "JGE," without a forsterite (Mg_2SiO_4) undercoating was developed. Because JGE has no hard coating such as forsterite, the lifetime of stamping dies is about ten times longer than with conventional grain-oriented steel sheets. Iron loss at the area between the tooth and yoke of the motor core is remarkably reduced using JGE. Therefore, the maximum motor efficiency of segmented core motors using JGE is higher than that with the highest grade of non-oriented steel sheet. Based on these results, JGE offers important advantages as a material for application to segmented core motors.
