چکیده :

Magnetic Gears (MGs) can be considered as the game-changer technologies when it comes to power transferring. They can not only transfer mechanical power touchlessly but also bring merits such as lower noise and vibration with respect to typical gears. However, utilizing permanent magnets (PMs) puts them under scrutiny in terms of cogging torque, which leads to the ripple on the torque profile. The use of reluctance cores instead of PM-assisted sides in one category of design introduces a cost-effective assembly and levels up rigidity and robustness, which is especially considerable in high-speed applications. However, the essence of saliency operation during the flux modulation causes less average torque and more torque ripple, too. This paper seeks a novel thought about increasing torque density, which includes structural modification by utilizing Halbach arrays as well as applying high-temperature superconductors (HTS) in flux channels. Due to the lack of numerical design equations, finite element analysis (FEA) alongside scenario analysis was used to show the effectiveness of the suggested assembly.
