동축 마그네틱 기어의 자석 재질에 따른 최적효율 설계 및 비교

다국어 초록 (Multilingual Abstract)

Various studies have been conducted since magnetic gears can replace mechanical gears and the non-contact power transmission characteristics of magnetic gears have emerged. Recent studies use rare earth permanent magnets to represent the high power density of magnetic gears. However, the conductive properties of the rare earth permanent magnets resulted in a decrease in efficiency. Using the ferrite permanent magnets, which have no conductivity, were difficult to compete in size. This paper presents the basic design of magnetic gears using three permanent magnet (NdFeB, Nd-bonded, Ferrite) materials and shows the results of size, efficiency characteristics.
