Magnetic gears are innovative systems that enable torque transmission without mechanical contact, eliminating common disadvantages associated with traditional mechanical gears, such as wear, maintenance requirements, and noise. One of the key advantages of magnetic gears is their inherent torque-limiting capability, which protects the system from overload. However, in certain applications, a fixed torque limit may not be desirable, and a dynamically adjustable torque transfer mechanism is required. In conventional magnetic gear systems, the maximum torque capacity is determined by the design parameters and the selected permanent magnets, which can limit operational flexibility. This study proposes a novel magnetic gear system capable of variable torque transmission capability, allowing for real-time adjustment of the torque-limiting characteristic. The proposed system enhances adaptability in various industrial and robotic applications, offering a significant advancement for systems requiring adjustable torque limit control.
