This paper proposes a new design method for sleeve thickness and interference based on a multi-dimensional visualization algorithm that overcomes difficulties in solving. The contact pressure between the rotor core and the permanent magnet, the maximum equivalent Mises stress of the permanent magnet, and the maximum equivalent Mises stress of the sleeve are selected as the optimization objectives. The stress limit strength of the permanent magnet and sleeve are taken as constraints, and the sleeve thickness and interference are selected as decision variables. Then the multi-dimensional visualization algorithm is used to find the optimal region of sleeve thickness and interference. Finally, the design solution is validated by the finite element method. The results show that the design method proposed in this paper can obtain the optimal region of sleeve thickness and interference with the characteristics of a simple solution process and intuitive results.
