Abstract

The invention discloses a stator winding coil, a stator winding, a stator, a motor and a vehicle, belongs to the technical field of motors. The coil is used for solving the technical problem that the winding welding space in the current motor is insufficient. The stator winding coil specifically comprises a coil body, and one end of the coil body is provided with a welding end; the welding end comprises a second vertical part and a second inclined part, one end of the second inclined part is connected with the coil body, the other end of the second inclined part is connected with the second vertical part, and a certain angle is formed between the width direction of the second vertical part and the width direction of the coil body. The coil has the advantages of large welding operation space, high welding efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator winding coil, a stator winding, a stator, a motor and a vehicle. Background technique [0002] At present, motors made of flat wire conductors, also known as motors with hairpin windings, are commonly used in new energy vehicles to improve the torque and efficiency of the motor. In order to form a three-phase symmetrical winding structure, motors using hairpin windings generally need to adopt processes such as flat wire conductor forming, wire insertion, twisting, and welding on the side of the twisted wire. During the twisting operation, the ends of the flat wire conductors to be welded are generally twisted in pairs to be radially opposite, that is, the welding surface between the two flat wire conductors of the same group is in the radial direction of the stator core. vertical. However, when there are many layers of flat wire conductors in the stator slot, such as fo...
