Abstract: This paper designs an embedded permanent magnet synchronous motor for the fully electric injection molding industry,and analyzes the electromagnetic noise sources of the motor using analytical methods; selecting magnetic steel thickness,magnetic steel V-shaped angle,stator slot depth,air gap length,and pole arc angle as independent variables,and electromagnetic torque,torque ripple,and radial electromagnetic force as dependent variables,an orthogonal experiment was established using Taguchi method to optimize the dependent variables. Finite element simulation software is used to calculate the output performance before and after optimization, as well as the noise pressure level at the main frequency points of the motor,providing reference for actual industrial production.
