Innovative Magnetic Gear Design Incorporating Electromagnetic Coils for Multiple Gear Ratios

Blog Article

In this study, a novel magnetic gear design is introduced.Unlike conventional magnetic gears that can only achieve a single gear ratio using permanent magnetic poles, the proposed design incorporates electromagnetic coils that can adapt to various control strategies, resulting in a multiple gear ratio for the same machine design.We selected a gear system with five gear ratios to validate the new design.The performance of the proposed design was compared with that of the Watch Bands conventional magnetic gear.

While permanent magnet poles offer high torque transmission with a small volume, they cannot provide different gear ratios for the same configuration.Therefore, this work suggests using a single-gear machine based on a fixed number of Craft Knife electromagnetic coils to achieve different gear ratios.This research outlines the design steps, simulation process, and detailed analysis.The results demonstrate the effectiveness of the proposed design strategy, which can be potentially applied to wind turbines, transportation, and other scenarios with comparable success.
