초록

자속 역전식 전동기(Flux Reversal Motor: FRM)는 고정자 치 표면에 영구자석을 갖는 구조이며 회전자가 돌극 형태이므로 관성이 적고 기계적으로 강인한 특성을 지녀서 고속기로의 적용이 가능하다. 그러나 단상 FRM은 구조적 특징으로 인하여 영구자석의 감자가 쉽게 일어나며, 고속 구동시 스위칭 주파수가 커짐에 따라 철손이 크게 상승하게 된다는 한계점을 지닌다. 본 논문에서는 유한요소법을 이용하여 단상 FRM의 설계 파라미터가 전동기의 감자특성에 주는 영향을 고찰해보았고 그 해결 방안을 제시하였으며 철손 특성을 분석하였다.

This paper presents the demagnetization and iron loss analysis of the single phase Flux Reversal Machine. It has a magnetic configuration similar to the switched reluctance machine but with multipole permanent magnets of alternate polarity on each stator salient pole embraced by concentrated coils. But it can be demagnetized by sudden over current and core losses increase because switching frequency is getting faster. This paper show demagnetization of permanent magnet and iron loss characteristic, and proposed a solution.
