The invention provides a stator of a centralized winding motor and a vehicle, and relates to the technical field of vehicles. The stator of the centralized winding motor comprises: a stator core configured to have a hollow cylindrical shape having an interlayer; a winding wire which is positioned in the interlayer; and a busbar assembly which comprises a bus bar pad, and a U-phase busbar, a V-phase busbar and a W-phase busbar which are formed by winding wire outlet ends, wherein the busbar pad comprises an installation part which is located on the inner side of the hollow cylinder of the stator core and used for installing the U-phase busbar, the V-phase busbar and the W-phase busbar and enabling the U-phase busbar, the V-phase busbar and the W-phase busbar to be separated from one another. The U-phase busbar, the V-phase busbar and the W-phase busbar in the stator of the centralized winding motor are arranged on the busbar pad and are separated from one another so that the UVW three-phase insulation electrical distance is increased, the insulation performance is better and the reliability is higher.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a stator of a centralized winding motor and a vehicle. Background technique [0002] The stator of the traditional block-type centralized winding motor, the structure from the outside to the inside includes: the outermost sheath, which is close to the sheath is a layer of insulating paper, and the inside is (all close to) the W-phase confluence row, insulating sheet, V-phase bus bar, insulating sheet, U-phase bus bar. Each phase bus bar is provided with soldering points at the corresponding position so that it can be welded with the outlet end of the corresponding three-phase line (the outlet end of each phase line is the head end or tail end after the winding is wound in the tooth slot). The U-phase at the outlet end of the winding is connected to the U-phase bus bar, the V-phase is connected to the V-phase bus bar, the W-phase is connected to the W-phase bus bar, and the U-ph...
