Stator core structure with asymmetric tooth shoulders for single-layer concentrated winding

The invention discloses a stator core structure with asymmetric tooth shoulders for a single-layer concentrated winding, and belongs to the technical field of servo motors. The widths of all teeth of the stator iron core are the same, every two winding teeth on the stator iron core form a group, the winding teeth are named as a base group, and the base group is composed of teeth with full tooth shoulders and straight teeth without tooth shoulders adjacent to the teeth with full tooth shoulders; a stator core adopts an asymmetric tooth shoulder and asymmetric notch structure, a stator winding is wound on teeth of a full tooth shoulder in a single-layer concentrated manner, a stator winding is not wound on straight teeth of a tooth shoulder-free manner, and a slot between the teeth of two adjacent asymmetric tooth shoulders is an unoccupied slot. The stator core structure provided by the invention has the technical effects that concentrated winding is convenient to realize, the occupied space of the end part is
