Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0014] Such as figure 1 -2. The stator of the split-tooth brushless motor in this embodiment includes: the stator 1 is formed by splicing a plurality of stator teeth 2 into a ring, and each stator tooth 2 is wound with a stator coil 3. The stator with this structure can greatly improve the stator core. The utilization rate of materials; it can realize simultaneous and high-speed winding of multiple stator teeth; it can improve the slot fullness rate.

[0015] The two sides of the stator teeth 2 are respectively provided with a tenon 4 and a tenon 5 for realizing splicing of the stator teeth 2 .

[0016] The cross section of the outer wall and the inner wall of the stator tooth 2 is arc-shaped.

[0017] Apparently, the above-mentioned embodiments are only examples for clearly illustrating the present invention, rather than limiting the implementation of the pre...

Abstract

The invention relates to a tooth-splicing type brushless motor stator, comprising a stator which is spliced into an annular shape by a plurality of stator teeth, and each stator tooth is coiled with a stator coil. Further, in order to provide convenience for splicing and installation, two sides of the stator tooth are respectively provided with a rabbet and a mortise used to realize splicing of the stator teeth. In order to make the stator teeth form an annular stator after splicing, cross sections of an outer side wall and an inner side wall of the stator tooth are in an arc shape. The tooth-splicing type brushless motor stator is formed by splicing a plurality of stator teeth, and the stator is not an integrated one, so that utilization rate of a stator core material is greatly improved, and a plurality of stator teeth can wind in high speed at the same time, and coil space factor can be improved.

Description

technical field [0001] The invention relates to a spliced-tooth type brushless motor stator. Background technique [0002] In the current permanent magnet brushless DC motor, the stator is an integral structure, the utilization rate of the stator core material is low, and the slot fullness rate is low. The slot full rate refers to the proportion of the space occupied by the coil after it is placed in the slot. Generally speaking, it is the ratio of the cross-sectional area of ​​the wire to the effective area of ​​the slot. [0003] How to improve the utilization rate of the stator core material and the slot fullness rate is a technical problem in this field. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a simple structure, the utilization rate of the stator core material and [0005] The stator of split-tooth brushless motor with high slot filling rate. [0006] In order to solve the above-mentioned technica...
