Abstract: The impact of armature winding distribution on electromagnetic force and vibration was analyzed in a 4-pole 10-slot brushed DC motor with different winding distributions. The analytical methods were used to analyze the mechanism and order characteristics of radial electromagnetic force; finite element simulation was used to analyze the temporal and spatial orders of air gap magnetic field and radial electromagnetic force for different wingding distribution models; combining
vibration testing and modal testing, explain the mechanism of additional electromagnetic force generated by difference in winding distribution on vibration. The results indicate that the influence of armature winding distribution on motor electromagnetic vibration cannot be ignored. It is necessary to consider the influence of armature winding distribution when analyzing motor vibration.

Key words: brushed DC motor, armature winding, winding distribution, electromagnetic force, electromagnetic vibration
