Technical Problems for Core Loss Reduction of High-Speed Motor


Article Preview

This paper describes the technical problems for upgrading efficiency by core loss reduction on high speed motor. These contents are based on the ultra-thin electrical steel sheet for motor core and vector magnetic characteristic technology. It is difficult to get successful results by replace of high performance core materials. Because the utilization technique of these materials is necessary as recipe for research and development of high efficiency high speed motor.
