Six-phase rectification generator winding coil inserting structure and coil inserting method

Abstract

The invention discloses a six-phase rectification generator winding coil inserting structure, which and relates to the technical field of motors, and. The structure comprises a stator core, the statorcore is provided with a first three-phase winding and a second three-phase winding, and the number of magnetic poles of a the stator is 4; wherein the difference between the first three-phase windingand the second three-phase winding is 30 degrees, and each phase winding of the three-phase windings comprises a first coil, a second coil, a third coil and a fourth coil which are sequentially connected in series; 24 wire slots are arranged along the circumference of the stator core, and a first ring edge of a phase coil in the first three-phase winding and a second ring edge of a phase coil inthe second three-phase winding are embedded in each wire slot. The invention further discloses a coil inserting method., coil Coil inserting of the front two-phase coil is completed by lifting while feeding, separating the coil from the groove and then falling into the groove, coil inserting of the subsequent coil edge can be completed only by connecting the previous inserted coil, coil insertingis simple and convenient, the winding is neat and compact, and the situation that the coil end is raised and cannot be shaped is avoided.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a wire-embedding structure and a wire-embedding method for a six-phase rectifier generator winding. Background technique [0002] With the development of the power system, more and more occasions require a generator system that can operate independently of the isolated grid. Since there is no phase difference in DC power, low-frequency oscillation will not occur, and the DC power transmission cost is low, the space is small, and the control is simple. Therefore, rectifier generators are required in many occasions. At present, six-phase rectifier generators use double Y-shift 30° windings, but there are also the following problems: [0003] The winding has six phases, and the coils are more and more complicated than ordinary three-phase motors, and there are many coil lead wires, which makes it difficult to insert the wire. One phase and one phase embedding will cause the ...

AI Technical Summary

Problems solved by technology

[0003] The winding has six phases, and the coils are more and more complicated than ordinary three-phase motors, and there are many lead-out wires from the coils, which makes it difficult to embed the wires. One phase and one phase embed the wires, which will cause the ends of the coils to rise, the ends of the windings cannot be shaped, and the windings are loose and messy.
