The invention provides a stator winding, a stator and a motor, the number of slots in each phase of each pole is three, any phase winding comprises a coil group I and a coil group II which are arranged on the radial innermost layer and the radial outermost layer of a stator core, the coil group I comprises a plurality of first conductor groups which are sequentially arranged along the circumferential direction of the stator core, and the coil group II comprises a plurality of second conductor groups which are sequentially arranged along the circumferential direction of the stator core. The coil group II comprises second conductor groups which are sequentially arranged in the circumferential direction of the stator iron core; the at least one third coil group is arranged on two adjacent layers in the radial direction of the stator core, the third coil group is arranged between the first coil group and the second coil group, and the third coil group comprises a plurality of third conductor groups which are sequ
