Multi-Objective Optimization and Analysis of Thrust on an Axial Magnetized Dual Stator 2DoFPM Machine Linear Component

Two degrees-of-freedom permanent magnet (2DoFPM) machines, which have high theoretical and practical value, are widely used in advanced manufacturing fields such as robotics and machine tools. This paper focuses on significant force ripples in the linear component of 2DoFPM machines and explores multi-objective optimization related to the output thrust of the linear component. First, on the basis of a theoretical analysis, the structure and operating principle of the 2DoFPM machine are briefly presented. Second, Taguchi's orthogonal array method is employed to design a simulation experiment. Third, three-dimensional finite element analysis (3D-FEA) of the machine is conducted. Last, through statistical analysis and data comparison, the optimal parameter combination is obtained.
