Calculation of Rotor Loss according to analysis of Harmonics for Permanent Magnet High Speed Motor

영구자석 고속모터의 고조파 분석을 통한 회전자 손실해석

High speed PM machines are being developed as motor/generators for gas-turbine generator sets in smaller power sizes, and as motors for number of applications including gas compressors, machine tools and turbo molecular pumps. Due to the high peripheral speed of the rotor and the relatively high conductivity of the magnets used, rotor eddy current loss can be substantial. This paper deals with the calculation of rotor eddy-current losse in permanent magnet(PM) high speed motor using the analysis of harmonics.
