Problems solved by technology

[0004] The smaller the diameter of the rotor shaft, the smaller the inner diameter of the stator core, and because the coil span of the two-pole motor is larger, the number of coils in the inner diameter of the stator core is more, which makes it difficult or even impossible to insert the stator coil. complete rule

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like figure 1 A method of embedding the windings of a high-speed motor as shown, the stator core has a total of 24 embedding slots, and all four connected coils of the first phase coil are embedded in the lower side, so that there are 10 unembedded coil sides in the stator core. The number is reduced to 6, which completely solves the problem of wire embedding of motors with small inner diameters.

[0028] The specific wire embedding process is as follows: firstly, the two coil sides of the smallest coil among the four connected coils of the first phase coil are embedded, and both are embedded in the lower layer, and then the two coil sides of the smaller coil among the four connected coils of the first phase coil are embedded. Each coil side is also embedded in the lower layer, and then the two coil sides of the larger coil among the four connected coils of the...

Abstract

The invention relates to a motor, in particular to a coil inserting method of a high-speed motor winding, which is different from the prior art in that four connected coils of a first phase coil are all embedded into a lower layer edge, so that the number of unembedded coil edges in a stator core is reduced from 10 to 6. According to the invention, the coil inserting method is improved, the coil inserting problem of the two-pole motor is successfully completed, the frequency of a centrifugal air compressor with the rotating speed up to 100000r/min can be minimized, the inner diameter of the stator core can be made to be smaller, and the problem of large centrifugal force is solved.

Description

technical field [0001] The invention relates to a motor, in particular to a wire embedding method for a high-speed motor winding. Background technique [0002] Typical 24 stator slotted concentric windings, the number of coils per pole and phase is divided into 4 types, which are the largest, the largest, the smallest and the smallest, and the spans are 13, 11, 9 and 7 respectively. line methods such as figure 1 Shown: first embed the lower side of the smallest coil among the four connected coils of the first phase coil, and the upper side is not embedded for the time being - called the handle, the same below. Then embed the lower side of the smaller coil, the upper side of the handle, then the lower side of the larger coil, the upper side of the handle, and then the lower side of the largest coil, the upper side of the handle, and then the fourth coil of the second phase. The lower side of the smallest coil among the connected coils, the upper side is raised, then the low...
