The invention relates to the technical field of automobiles, and discloses a hairpin winding type motor stator and a motor. The hairpin winding type motor stator comprises an iron core and a stator winding. A plurality of stator slots are formed in the iron core, and the iron core comprises an inserting side and a welding side. The stator winding is arranged in the stator slots and comprises a plurality of hairpin windings, each hairpin winding comprises a plurality of hairpins with the same shape, the two ends of each hairpin penetrate into the stator slots from the inserting side and penetrate out of the welding side, and the hairpin windings form a plurality of hairpin layers. The two ends of the hairpins arranged on the welding side are bent towards the two sides by the same number ofslots, so that the ends of the hairpins of the adjacent hairpin layers are in one-to-one correspondence, and the ends of the hairpins are connected with the ends of the adjacent hairpins which are arranged on different layers and in the same column according to rules. By using the hairpin winding type motor stator provided by the invention, automatic connection and subsequent processing are facilitated, the size of the motor is reduced, the structure of the motor is simplified, and the product quality and consistency are good.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a hairpin winding motor stator and motor. Background technique [0002] With the rapid development of new energy vehicle technology, the performance requirements of the motor are getting higher and higher. The increase in performance will inevitably lead to the complexity of the motor structure, and the contradiction between the performance of the motor and the complex structure is becoming increasingly prominent. [0003] The stator winding of an existing motor generally adopts round wires to form a coil, and the cross-sectional shape of the stator winding can be divided into a circular coil and a square coil. Compared with circular coils, square coils can effectively increase the slot fill rate of the motor, reduce the copper consumption of the motor to improve the efficiency of the motor, and at the same time reduce the height of the end of the motor stator winding, thereb...
