초록

종래의 터보기기는 회전자의 높은 회전속도를 얻기 위하여 증속기어를 사용하였으나 근래에는 초고속 전동기를 적용하여 기계적인 효율 및 시스템의 소형차에 관한 연구가 활발히 진행중이다. 본 논문은 직접구동방식의 터보 압축기를 위한 초고속 영구자석 동기전동기 구동시스템에 관한 논문으로서 150마력 70,000rpm 영구자석 동기전동기 구동시스템을 개발하여 상품에 적용하였다.

Turbo compressor needs high speed rotation of impeller in structure, high rated gearbox and conventional induction motor. This mechanical system increased the moment of inertia and mechanical friction loss. Resently, the study of turbo compressor applied super high speed motor and drive, removing gearbox made its sire small and mechanical friction loss minimum. This paper describes the implementation of the vector control schemes for a variable-speed 131㎾ PMSM(Permanent Magnet Synchronous Motor) drive in super-high speed application.
