Abstract
Description
Technical Field
[0001] The utility model relates to the field of winding devices, in particular to a low-loss stator winding device for three-phase AC motors. Background Technique
[0002] The stator winding refers to the winding installed on the stator, that is, the copper wire wound on the stator. The winding is a general term for a phase or the entire electromagnetic circuit composed of multiple coils or coil groups. According to the shape of the coil winding and the installation wiring method, motors can be divided into two categories: concentrated type and distributed type. The winding and installation of the concentrated winding are relatively simple, but the efficiency is low and the operating performance is also poor. Most of the stators of AC motors use distributed windings. According to different machine types, models and coil winding process conditions, each motor is designed to adopt different winding types and specifications.
[0003] For most existing stator windings, when repairing or manufacturing the windings, it is often necessary for workers to manually place the copper wire in the corresponding position of the stator, and then start the machine to wind the winding. It is necessary to frequently change the orientation of the stator to wind different positions, so as to complete the stator winding. Its use is complex, and the situation of winding errors often occurs, resulting in losses of manpower and copper wire. Moreover, the surface of the copper wire is not cleaned, and it is easy to be mixed with oil stains, sundries, etc. Content of the Utility Model

One ends of the two telescopic rods 7 far away from the hydraulic pumps 6 are fixedly connected with a pushing plate 8. One side of the pushing plate 8 is fixedly connected with two wire blocking plates 9. And a rotating rod 26 is arranged on the opposite side of the two wire blocking plates 9. One end of the rotating rod 26 sequentially penetrates through the pushing plate 8 and a connecting block 25 and is connected with the output end of a first motor 4. And the connection part of the rotating rod 26 and the first motor 4 is movably connected through a bearing. One end of the rotating rod 26 far away from the first motor 4 is fixedly connected with a winding plate 10. One side of the winding plate 10 is fixedly connected with two winding rollers 11.
[0026] As Figure 1 shown, one side of the top end of the base 1 is fixedly connected with a fixing seat 12. A connecting rod 14 penetrates through one side of the fixing seat 12. And one end of the connecting rod 14 is connected with the output end of a second motor 13. One end of the connecting rod 14 far away from the second motor 13 is fixedly connected with a cleaning brush 15. By arranging the second motor 13, the connecting rod 14 is driven to rotate by the second motor 13, so that the connecting rod 14 drives the cleaning brush 15 to clean the copper wire in the winding operation in real time, preventing the oil stains and sundries on the copper wire from affecting the stator power generation.
[0027] As Figures 1-4As shown in the figure, on one side of the top end of the base 1, a connecting plate 16 is fixedly connected. On one side of the inner wall of the connecting plate 16, a winding plate 17 is clamped by a fixing bolt 18. On one side of the upper end surface of the base 1, a clamping plate 19 is fixedly connected. The outer wall of the clamping plate 19 is movably connected with a stator 20.
