Magnetic gears have been proposed as a means of increasing torque density within electromechanical systems, while avoiding problems associated with traditional mechanical gears. While the idea behind magnetic gears goes back to early patents, their study and use in industry has been very limited to date. This study looks into variations of the concentric planetary magnetic gear which could lead to further use. It also investigates applying winding function theory (WFT) to aid in analysis of the gear. The new application of winding function theory is verified with the use of finite element analysis (FEA) as well as a prototype which has been fabricated.
