The stator core 1 includes a core body 11, an insulating frame 12, and a hook frame 4. The core body 11 is provided with a winding tooth assembly 3, which includes six circumferentially distributed winding teeth. The insulating frame 12 is located on the outer periphery of the core body 11, and the hook frame 4 is located on the insulating frame 12. The hook frame 4 includes three hooks. A conductor 2 is wound around the six winding teeth and the three hooks to form a triangular connection of two in series or two in parallel. After the insulating frame 12 is fitted onto the outer periphery of the core body 11, the six winding teeth, except for the inner surface, are partially or completely covered by the insulating frame 12, so that the conductor 2 and the core body 11 are insulated from each other, preventing short circuits caused by current flowing through unexpected paths.

The middle part of the wire 2 is supported by the winding teeth and hooks, which avoids the situation where the end of the wire 2 has no support point at the winding teeth. This reduces the possibility of the end of the wire 2 becoming loose or unraveling after winding. In addition, the middle part of the wire 2 has a certain tension after winding, which makes the wire 2 wrapped around the winding teeth, reducing the possibility of the wire 2 detaching from the winding teeth and hook frame 4, thereby improving the stability of the stator.

In this embodiment, the wire 2 is wound by only one wire 2, and the wire 2 is wound in the form of a triangle connection in parallel with each other in sequence after being hooked on the first wire hook 41, until the wire 2 is hooked on the first wire hook 41 again, and the wire 2 is fixed at both ends after being wound, thereby improving the stability of the wire 2 after being wound, and reducing the possibility of loosening, disordered winding and broken wire of the wire 2; the middle part of the wire 2 does not have the lap joint of two wires 2, further reducing the loosening, disordered winding and broken wire of the wire 2.

In this embodiment, the wire 2 is wound by only one wire 2, and the wire 2 is wound in the form of a triangle connection in parallel with each other in sequence after being hooked on the first wire hook 41, until the wire 2 is hooked on the first wire hook 41 again, and the wire 2 is fixed at both ends after being wound, thereby improving the stability of the wire 2 after being wound, and reducing the possibility of loosening, disordered winding and broken wire of the wire 2; the middle part of the wire 2 does not have the lap joint of two wires 2, further reducing the loosening, disordered winding and broken wire of the wire 2.

[0044] In the embodiment, as shown in Figure 4 and Figure 9 As shown, the connecting ribs 111 are circumferentially connected by annular rib bodies 113 between adjacent connecting ribs 111, the annular rib bodies 113 are integrally connected with the inner wall of the core body 11, the annular rib bodies 113 support the wire 2 between adjacent winding teeth, thereby reducing the instability of the wire 2 between adjacent connecting ribs 111 due to lack of support, and thereby affecting the stability of the wire 2 winding. Further, the inner side of the annular rib body 113 is provided with a blocking rod 114, by the arrangement of the blocking rod 114, the wire 2 supported on the annular rib body 113 is blocked by the blocking rod 114, thereby reducing the possibility of the wire 2 being separated from the annular rib body 113, and further improving the stability of the wire 2 between the adjacent two winding teeth.
[0045] In order to distinguish the wire 2 wound on the winding tooth and the wire 2 passing through the winding tooth, the outer end of the connecting rib 111 is provided with a blocking block 115, and the wire 2 extends through a wire passing bridge 116 between the blocking block 115 and the inner side wall of the core body 11, when the wire 2 passes from the outer side of the winding tooth, the wire 2 extends in the wire passing bridge 116, so that the blocking block 115 distinguishes the wire 2 wound on the winding tooth and the wire 2 passing through the winding tooth, and also facilitates judging whether the wire 2 winding is wrong.
[0046] In another embodiment, as shown in Figure 2 The insulating frame 12 includes an upper insulating frame 121 and a lower insulating frame 122, the upper insulating frame 121 and the lower insulating frame 122 are respectively sleeved on both ends of the core body 11, when the stator structure plays a supporting role, the upper insulating frame 121 and the lower insulating frame 122 play a protective role, thereby reducing the possibility of affecting the service life of the core body 11 due to wear; when the wire hook frame 4 is connected with the insulating frame 12, the wire hook frame 4 is fixedly installed through the mounting seat 5; specifically, the mounting seat 5 is connected between the upper insulating frame 121 and the lower insulating frame 122, and plays a role in stabilizing the upper insulating frame 121 and the lower insulating frame 122; the wire hook frame 4 is installed through the mounting seat 5, specifically, as shown in Figure 9 andFigure 10 As shown, the outer wall of the mounting base 5 is provided with multiple protruding ribs 51. The outer wall of the protruding rib 51 is in the shape of "I" or it can be a "T" with a width on the outer side of the mounting base 5 that is greater than the width on the inner side of the mounting base 5. An installation gap 52 is formed between two adjacent protruding ribs 51. The hook frame 4 is embedded in the installation gap 52 to fix the hook frame 4 in the radial direction of the iron core body 11. The hook frame 4 is embedded in the installation gap 52 to facilitate the stability of the hook frame 4 before it is fixed, thereby facilitating the installation of the hook frame 4.
[0047] To facilitate distinguishing the hooking sequence of conductor 2, such as Figure 9 As shown, the upper insulating frame 121 has two dividing posts 44 on its end face, and a gap 45 is formed between the two dividing posts 44. The gap 45 is directly opposite the second hook 42 located in the middle on the radial side of the iron core body 11. When the conductor 2 is hooked to the second hook 42, it enters and exits through the gap 45. The conductor 2 hooked to the first hook 41 and the second hook 42 extends from the outside of the dividing post 44, which makes it easier to distinguish the conductor 2 hooked to the first hook 41, the second hook 42 and the third hook 43, thereby reducing the possibility of winding errors of the conductor 2 and improving the accuracy of winding of the conductor 2.
