چکیده :

The growing demand for high-efficiency and low-maintenance power transmission systems has accelerated interest in magnetic gearing technologies. Compared with conventional mechanical gears, magnetic gears offer silent operation, improved reliability, and inherent overload protection, making them highly attractive for modern transportation and renewable energy applications. This paper presents the design, analysis, and optimization of a novel Double-Layer Radial-Flux Magnetic Gear (DLRFMG) aimed at improving torque density and reducing torque ripple. The proposed structure employs two torque conversion layers to achieve a higher gear ratio and torque transmission capability. To optimize the performance, the Taguchi method was applied with an L27 orthogonal array, enabling multi-objective optimization of maximum applicable torque and torque ripple across all rotors with minimal experiments count. The results demonstrate significant improvements, with maximum torque enhanced by up to 72.45% and torque ripple reduced by more than 60% compared with the initial design. Analysis of variance (ANOVA) further identified the dominant influence with their corresponding percentages of the most effective control factors. The optimized DLRFMG exhibits superior torque characteristics, making it a promising solution for applications such as electric bicycles, transportation systems, and renewable energy devices.
