300마력 60000rpm급 초고속 전동기의 실측 전류 파형을 고려한 손실 특성 해석

This paper deals with comparison and analysis for various losses of high-speed permanent magnet synchronous motor using phase current harmonic analysis. Through measured current wave, various losses are calculated and compared with losses according to current sine wave. Poynting vector, Steinmetz equation, finite element method and so on have been used to investigate the losses of high-speed permanent magnet machine.
