Abstract: Aiming at the solutions of leaking problems exist in some special industries including the vacuum robot area, we bring out the technology of magnetic transmission module used for ultra-high vacuum robot. Though the magnetic transmission technology had been expanded rapidly for decades with the development of magnetic materials in the 1970s, there are scarcely some cases using magnetic transmission for robots in China. The principle of the magnetic transmission is presented in the beginning of this paper and then we introduce the designing process of the magnetic coupling. During the process of designing, we use the ANSYS software to do analysis of the magnetic circuit to achieve optimisation. In the end of this paper, we draw a conclusion that the magnetic coupling designed by us is fit for the power transportation for ultra-high vacuum environment and the torque can be transmitted to meet the designing goal.

Keywords: magnetic transmission; ultra-high vacuum robots; magnetic circuit optimisation; FEA; finite element analysis; magnetic coupling; China; robot design.
