Axial field motor, stator assembly and stator winding process

Abstract

The invention discloses a stator assembly, through sequentially implemented process steps such as unit body winding, multi-unit preparation, winding assembly and stator embedding, the winding of a single unit body can be realized by relying on a single flat wire, and the whole In the unit body structure, the winding of the stator winding can be completed only by the bending process, and the reliable layout and relative structure shaping between the conductors can be realized without additional processes such as welding, which greatly reduces the difficulty of the stator winding process, simplifies the process steps, and improves The efficiency of the process operation is improved, and the winding arrangement is regular and beautiful, so that the stator winding after winding can be embedded in the corresponding slot of the stator housing as a whole, thereby further reducing the difficulty of the embedded wire assembly of the stator assembly and realizing efficient automatic insertion. Wire assembly, while reducing the process cost and the overall manufacturing cost of the motor. The invention also discloses a stator assembly manufactured by the above-mentioned stator winding process and an axial magnetic field motor using the stator assembly.

Description

technical field [0001] The invention relates to the technical field of axial magnetic field motor stator matching technology, in particular to a stator winding technology. The invention also relates to a stator assembly manufactured by the stator winding process and an axial field motor using the stator assembly. Background technique [0002] In the current axial field motor stator processing and assembly process, the generally adopted stator winding methods are usually divided into centralized winding and distributed winding. [0003] Specifically, the centralized winding usually winds a coil on a stator tooth, and its embedding process is simple, but it will generate large harmonics in the motor magnetic field, which reduces the performance of the motor; while in the distributed winding structure, A coil usually spans multiple stator teeth. This type of winding structure has a relatively complicated wire embedding process, but the harmonics of the motor magnetic field are...

[0003] Specifically, the centralized winding usually winds a coil on a stator tooth, and its embedding process is simple, but it will generate large harmonics in the motor magnetic field, which reduces the performance of the motor; while in the distributed winding structure, A coil usually spans multiple stator teeth. This type of winding structure has a more complex wire embedding process, but the harmonics of the motor magnetic field are small and the motor performance is better.
