The stator design optimization method based on the response surface model is proposed to solve various problems in the design and optimization of the stator structure of the motor. They include that the stator design mode of the stator is not completely separated from the disturbance mode, the stator vibration amplitude is small and the stator vibration is large in the local internal stress. First, the sample point is selected in the design space for the Latin hypercube sampling method when setting the stator design size as a variable. The stator modal and harmonious response value is obtained by the finite element analysis of the stator size structure obtained by the combination of each sample point, and the stator response surface model is established. Then, the remains are used. The transmission algorithm optimizes the stator on the basis of the response surface model. Finally, the finite element software is used to model the stator before and after the optimization to verify the correctness of the optimization results.
