The invention relates to the technical field of stepping motors, in particular to a method for optimizing a stepping motor stator, and the method comprises the following steps: S1, keeping the stator diameter, the rotor diameter, the phase number and the step angle of a stepping motor unchanged, and reducing the number of pole pairs of each phase of the stepping motor; s2, increasing the number of windings on each large pole; and S3, adjusting the mechanical angle between the large pole center lines of the adjacent large poles, or adjusting the mechanical angle between the stator small tooth center lines of the adjacent large poles, so that the step angle is not changed under the condition that the beat number of the stepping motor is not changed before and after the number of pole pairs of each phase is reduced. According to the stepping motor, the number of pole pairs of each phase on the stator is reduced, and the mechanical angle between the large pole center lines of the adjacent large poles or the mecha
