The axial electromagnetic force wave is the main noise origin for axial flux motor. A finite element method parametric model was built up based on axial-fluxin-wheel motor (AFWM). Based on the parametric model, the orthogonal experiment was designed with taking the thickness of permanent magnet, the length of air gap, the chamfer length of permanent magnet, the width of stator slot, and the hole of stator tooth as structural parameters. And sensitivity analysis for structural determinants that can affect axial electromagnetic force wavewas carried out. Based on the resultof orthogonal experiment, the mathematical model of calculating mainly axial electromagnetic force amplitude and average torque was established respectively by BP neural network. Then with the optimization goal of reducing the main axial force amplitude and improving the average torque, the multi-objective genetic algorithm was adopted to optimize the structural parameters of the motor. The FEM results show that the most optimized structural parameterscombination not only can effectively reduce the electromagnetic noise and improve the output performance of the motor.
