Abstract: The output torque is the most important index for the design of disc type permanent magnet coupler, the output torque characteristics of a detailed analysis of disc type permanent magnet coupler, starting from the analysis of the eddy current field theory and equivalent magnetic circuit theory, deduced the disc type permanent magnet coupler output torque formula, analysis of the important parameters of permanent magnet thickness, air gap and the thickness of copper the thickness of the output torque. By using the finite element software Ansys, established the 3D model of disc type permanent magnet coupler, the finite element simulation analysis of transient field, verify the correctness of the conclusion, provides a theoretical basis for the optimization design of disc type permanent magnet coupler.
