Motor winding and motor

The invention provides a motor winding and a motor, the motor winding comprises a stator iron core and a plurality of stator conductors, the stator iron core is provided with a plurality of wire outlet grooves distributed along the radial direction of the stator iron core, each wire outlet groove is internally provided with a plurality of stator conductors with different phases, and each stator conductor comprises a connecting section extending out of the wire outlet groove. The connecting sections are distributed along the circumferential direction of the stator core and form a plurality of ring layers; the connecting sections of the plurality of stator conductors form a plurality of welding pairs, and each welding pair comprises two connecting sections which are positioned on adjacent ring layers and have the same phase; and the spans of the two mutually welded connecting sections in at least one pair of adjacent ring layers are different. According to the invention, the two mutually welded stator conductor
