The invention relates to a stator winding of a flat-wire motor and a motor. The stator winding of a flat-wire motor includes a stator and a three-phase winding structure. Each phase winding structure has four branches formed in parallel through a star connection. Each phase winding structure Both include the insertion side and the welding side, the welding side is arranged with lead-out terminals and multiple star points, and the insertion side is arranged with hairpin lines; among the 4 branches of each phase winding structure, 2 branches are adjacently connected and arranged on the welding side. On the outermost side, the other two branches are adjacently connected and arranged on the innermost side of the welding side. The outermost star points are welded to the first copper bar, and the innermost star points are welded to the second copper bar. , the 4 branches of each phase winding structure are welded to the corresponding third copper bar on the welding side. In the stator winding of the flat wire motor, the star points are concentrated on the outermost and innermost sides of the welding side. All the star points need to be welded on the copper bars on the outermost and innermost sides. The welding is simple and convenient, which can reduce the difficulty of welding.
Description
technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a flat wire motor stator winding and the motor. Background technique [0002] At present, the stator windings of the drive motors of new energy vehicles mostly use round wire structures (motors with stator windings using round wire structures are hereinafter referred to as round wire motors). It is increasingly difficult for round wire motors to meet the requirements of complete vehicles. Compared with round wire motors, flat wire motors (motors whose stator windings use a flat wire structure) have the advantages of high slot fill rate and high power density. [0003] In an existing flat wire motor stator winding, the hairpin wires with different pitches, the neutral point, and the three-phase wire outlets of the winding are all arranged on the welding side, which increases the height of the end of the solder joint side and the difficulty of welding, and the risk of w...
