[Method] The mathematical model of the three-dimensional moving eddy current field was built,and the numerical methods of eddy-current losses and torque was derived. The key parameters were analyzed by electromagnetic simulation software, such as the number of magnetic poles, the thickness of the permanent magnet, the air-gap and the thickness of double cylindrical copper sleeve, which affect the output torque. [Result] The Optimal selection principle of the key parameters were de- rived by using the finite element and numerical analysis,which verified by test. [Conclusion] The research method for the magnetic circuit structure design and torque calculation of the adjustable permanent mag- netic driver in this paper was an effective method for improving performance.
