Abstract

To predict efficiency of interior permanent magnet synchronous motor (IPMSM) for traction motor and to cope with the risk of demagnetization in the permanent magnets, accurate iron loss analysis and understanding of the characteristic of the iron loss are very important at motor design stage. In this paper, we present the method to estimate the iron loss for the IPMSM considering the driving conditions such as both field weakening control and maximum torque per ampere control.

차세대 고속 전철용 매입형 영구자석 전동기의 효율 및 매입된 자석의 감자를 방지하기 위해서 정확한 철손해석과 철손특성을 이해하는 것은 전동기 설계단계에서 매우 중요하다. 본 논문에서는 견인전동기의 약계자 제어 및 최대토크 제어와 같은 구동상황을 고려하여 운전영역별 철손해석을 수행하고 특성을 분석하고자 한다.
