Short summary
This article introduces a new type of magnetic coupler which overcomes traditional limitations such as poor scalability and limited torque control. Its stackable disks and unique flux adjustment mechanism enable precise and wide-range torque adjustment without moving the disks. Through modeling verification, this design achieves high torque and excellent controllability, providing a practical solution for high-performance magnetic transmission in compact industrial applications.
