要約(英語): A planetary type magnetic gear consists of coaxial inner and outer rotors with surface-mounted permanent magnet, and ferromagnetic stationary parts called pole-pieces. It offers desirable features which conventional mechanical gears do not have, such as low maintenance and acoustic noise, and inherent overload protection. This paper presents a comprehensive study of the influence of geometry and position of the pole-pieces on torque performance based on finite element analysis (FEA) and experiments. Surveyed parameters of the pole-pieces include lengths in radial and axial direction, width in circumferential direction, and position in radial direction. Finally, it is demonstrated that the maximum torque of the improved prototype gear is increased by 45% and the maximum efficiency achieves up to about 99%.
