Stator structure, motor, drive assembly, and vehicle

Abstract

The present invention relates to a stator structure, a motor, a drive assembly and a vehicle, the stator structure comprising: an annular iron core component, in which a plurality of winding slots are arranged on an internal wall of the iron core component; and three-phase windings, in which each in-phase winding comprises a plurality of parallel winding branches, the winding branches being rotationally symmetrical in the circumferential direction.Each winding branch comprises a plurality of hairpin windings connected by connecting cables and having different pitches; a winding slot is divided into M layers along the radial direction of the iron core component; the M layers of hairpin windings are arranged in each winding slot; the hairpin windings in each winding branch pass through M layers of slots in different winding slots; and the three-phase windings are arranged periodically in sequence along the circumferential direction, with each hairpin winding inserted into the corresponding winding slots.
