Research on motor with nanocrystalline soft magnetic alloy stator cores

Abstract

The authors built a prototype motor with NANOMET stator cores. NANOMET is one of the several nanocrystalline soft magnetic alloys [see ref. 1]. Motor iron loss and other characteristics were compared with 35A360 (Japanese Industrial Standards), which is one of the widely used conventional electromagnetic steel sheet, and the effectiveness of the new material is shown. This study describes the method to build NANOMET stator cores, and presents the evaluation results of the prototype motor.
