Abstract：For adjustable-speed magnetic couplers， mechanical properties and adjustable-speed characteristics are both important characteristics. In order to realize the speed regulating function better， these two characteristics above should be studied deeply. An axial-flux solid asynchronous magnetic coupler was proposed， and the calculation model of the transmitted torque was established. From this， the adjustable-speed relationship expressions were derived under the constant torque load and variable load torque conditions， respectively. Moreover， the relationships between the torque and the speed regulation were solved by discretization. In addition， the above two working characteristics of the coupler were simulated by finite element method， respectively. Particularly， the curves of mechanical property and adjustable-speed characteristic were also obtained， and the optimal air gap control ranges under the two different conditions of the constant torque load and variable torque load were determined. Furthermore， the adjustable-speed relationships when the constant torque load or variable torque load were verified experimentally， and the experimental results are in good agreement with the results of theoretical calculation and simulation analysis.
