Abstract

This paper presents the development of high efficiency (IE5-class) industrial motor with an amorphous core for large capacity applications. Interest in saving energy increases on a global scale, and the high efficiency of the motor attracts attention. As for the motor of the field of industry, legal regulation to IEC standard is promoted in each country. We developed the magnetic characteristic evaluation technology and highly precise analysis design technique in the motor to reduce a loss more from the IE4 efficiency class. We found core structure to reduce the loss of the amorphous metal core, and the trial motor was able to achieve an efficiency class of IE5 by applying it.
