Abstract: Based on the magnetic circuit analysis of the traditional single-layer disc permanent magnet eddy current coupling, an integral double-layer disc permanent magnet eddy current coupling was designed. The coupling installed the permanent magnets of two single-layer disc permanent magnet eddy current couplings on the front and back of a piece of back iron in a N-S corresponding manner, thus, reducing the loss caused by the back iron reluctance in the magnetic circuit, improving the magnetic energy utilization rate of the permanent magnet and increasing the torque. Through the equivalent magnetic circuit method, a mathematical model of the structure was established, and combined with the finite element method simulation model, the torque characteristics were comprehensively analyzed. A prototype of the permanent magnet eddy current coupling was built, and the reliability of the above analysis was verified through experiments. The results show that the mathematical model built is accurate; and the torque of the coupling is greatly improved compared to the torque of the traditional permanent magnet eddy current coupling.
