Description

Technical Field

[0001] The invention relates to the technical field of generator winding connection structures, and in particular to a generator Z-type stator winding phase connection structure. Background Art

[0002] Stator winding refers to the winding installed on the stator, that is, the copper wire wound on the stator. Winding is a general term for a phase or the entire electromagnetic circuit composed of multiple coils or coil groups. Electric motors can be divided into centralized and distributed types according to the shape of the coil winding and the embedded wiring method. The winding and embedding of centralized windings are relatively simple, but the efficiency is low and the operating performance is also poor.

[0003] The original generator Z-type stator winding phase-to-phase connection adopts the method of leading the phase-to-phase connection leads of each coil of each phase to the winding ends and directly connecting them to each other. Although the structure is simple, each lead must be insulated. When they are put together, the winding ends are bloated, the dimensions are out of tolerance, and the wiring is messy. It is very easy to cause insulation damage during the shaping process, affecting the quality of the generator Z-type stator winding. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a generator Z-type stator winding phase-to-phase wiring structure, which overcomes the deficiencies of the prior art and effectively solves the problem of end wire size deviation and shaping insulation damage when the generator Z-type stator winding is connected in phase.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A generator Z-shaped stator winding phase connection structure comprises a stator, on the peripheral outer wall of which are fixedly connected phase connection copper rings distributed at equal distances, and short leads are welded on the outer walls of the phase connection copper rings, the short leads and the phase connection copper rings are welded by brazing, and a butt connection wire is fixedly connected to the outer wall of one end of the short lead.

[0007] Preferably, the lengths of the short leads on the phase-to-phase connecting copper rings decrease in sequence clockwise, and the short leads show periodic changes.

[0008] Preferably, an organic shell is fixedly connected to one side of the interphase connecting copper ring on the outer wall of the stator.

[0009] Preferably, a winding is provided on the inner wall of the stator, and one end of the butt-joint wire is connected to the outer wall of the winding.

[0010] Preferably, a rotor is arranged at the center of the inner wall of the stator and inside the winding.

[0011] The beneficial effects of the present invention are:

[0012] 1. The phase-to-phase connection structure of the Z-type stator winding of the generator of the present invention uses a phase-to-phase connection copper ring to replace the original long lead wire of the body of each phase connection, and the phase-to-phase connection lead head of each coil of each phase only leads out a short lead wire, which solves the problem that the end wire size is easy to exceed the tolerance and the shaping insulation is damaged when the Z-type stator winding of the existing generator is connected in phase, and improves the quality of the phase-to-phase connection of the Z-type stator winding of the generator;

[0013] 2. The phase-to-phase wiring structure of the generator Z-type stator winding of the present invention effectively improves the quality of the phase-to-phase wiring of the generator Z-type stator winding. This phase-to-phase connection structure also has a certain degree of versatility. By connecting copper rings, it solves the problem of bloated and messy ends caused by too many end leads, and effectively solves the problem of easy out-of-tolerance wire size and shaping insulation damage at the end of the generator stator winding.
