Abstract: Aiming to resolve the problems of vibration and low efficiency, the novel dual three phases meshing motor was designed. A simple and quite accurate model based on finite element method was presented to analyze the nonlinear magnetic field and dynamic model of motor in this paper. The geometry structure, electromagnetic parameters and control model were simulated and studied as a whole. The design to control and dynamic performance of motor were considered by data transfer from Ansoft. Maxwell to Matlab. A simulation was taken for a translational meshing motor under switch control method. The prototype was manufactured and the torque experiment was implemented. Practical limitations have been incorporated in the simulation model to make it closer to the experimental setup. The results of simulation are corresponding with experiment results, which validate the effective of the simulation model.
