Description

Technical Field

[0001] The invention relates to the technical field of motors, in particular to a flat wire motor winding. Background Art

[0002] The flat wire motor is a new type of motor that uses flat copper wire windings. The winding of the flat wire motor is one of its core components. The flat wire winding usually adopts a hairpin structure, that is, the flat wire is bent into a hairpin-like shape and then inserted into the stator slot. In order to further improve the performance of the motor, the flat wire motor winding usually adopts a multi-layer structure. Multi-layer windings can increase the number of conductors and improve the output power and efficiency of the motor. At present, in the field of new energy, most flat wire motors use full-pitch windings. However, this winding method has certain disadvantages. Due to the characteristics of full-pitch windings, the harmonic content of the motor is relatively large. This problem will bring many adverse effects. The first is the large fluctuation of the motor torque. The unstable torque will cause the motor to output unstable power during operation, affecting the normal working efficiency and performance of the equipment.

[0003] The Chinese patent with publication number CN118214190A proposes a winding structure, a stator assembly and a motor. The winding structure includes winding circuits of three phases and phase copper bars and star point copper bars. The winding starting positions of the 2m parallel winding branches of the winding circuit of each phase are respectively wound in m conductor slots. The m winding branches whose winding starting positions are at the outermost sides of the m conductor slots all circulate in the first winding direction or in the first winding direction and the second winding direction in sequence, and the winding end positions are all the innermost or outermost sides of the m conductor slots. The m winding branches whose winding starting positions are at the innermost sides of the m conductor slots all circulate in the second winding direction or in the second winding direction and the first winding direction in sequence, and the winding end positions are all the innermost or outermost sides of the m conductor slots. The winding structure can avoid the problems of difficulty in preparation and high cost of the three-phase winding structure due to the relatively large size and relatively complex structure of the phase copper bars and the star point copper bars.

[0004] However, the technical solution of this patent has the following problems: This patent divides the 2m parallel winding branches of each phase into two groups and sets the winding starting positions at the outermost and innermost sides of m consecutive conductor slots. This can make the three-phase copper bars have a relatively simple structure, but the winding structure needs to be connected by copper bars, which increases the mass and cost of the motor.
