[0002] Currently, brushless DC motors include stator assemblies and rotor assemblies. The stator assembly includes a stator core, a winding frame, and windings. The windings are wound on the winding frame, and the winding frame is assembled on the stator core.

[0003] However, the inventors of this utility model discovered during the development of this utility model that: the winding frame typically includes a first winding frame and a second winding frame. The first winding frame is inserted into one end of the stator core, and the second winding frame is inserted into the other end of the stator core. Then, the first winding frame and the second winding frame abut against each other. The height of the winding frame formed by the abutment of the first winding frame and the second winding frame is fixed. Therefore, one winding frame can only be matched with one type of stator core. The stator core is formed by stacking multiple stator iron sheets. When adding stator cores and adjusting the thickness of the stator cores, there is a gap between the first winding frame and the second winding frame. To meet the insulation requirements, insulating paper needs to be inserted into the gap, which is very troublesome. Utility Model Content

[0020] Please see Figure 1 The winding frame includes a first winding frame 1 and a second winding frame 2. The first winding frame 1 includes a first chuck 11 and a plurality of first plug-in portions 12. The plurality of first plug-in portions 12 are fixedly spaced to the first chuck 11. One end of the first plug-in portion 12 opposite to the first chuck 11 is provided with a groove 121. The second winding frame 2 includes a second chuck 21 and a plurality of second plug-in portions 22. The plurality of second plug-in portions 22 are fixedly spaced to the second chuck 21. The second plug-in portion 22 is provided with a protrusion 221. One second plug-in portion 22 is inserted into the groove 121 of one first plug-in portion 12. By adjusting the depth of the second plug-in portion 22 inserted into the groove 121, the distance between the first chuck 11 and the second chuck 21 is adjusted, thereby adjusting the height of the winding frame. For the first throttle portion 11 mentioned above, please refer to Figures 2-5 The first chuck 11 includes a first wire-concealing groove 111, a first outer wire-blocking plate 112, a first wire-binding groove 113, a first arc-shaped transition portion 114, and a first clearance groove 115. The first wire-concealing groove 111 is disposed between two adjacent first insertion portions 12. The first wire-concealing groove 111 is used to accommodate the winding cable. Accommodating the winding cable in the first wire-concealing groove can prevent it from encroaching on the stator space during wire binding. The first outer wire-blocking plate 112 extends from the end of the first chuck 11 away from the second chuck 21. The first outer wire-blocking plate 112 is provided with a plurality of first wire-passing grooves 1121. The first wire-passing grooves 1121 are used to accommodate the winding cable. During wire binding, the cable can be wrapped around the first wire-passing groove in an S-shape before binding, which helps to maintain the tension of the binding and makes the binding less difficult. The first chuck 11 has a first binding groove 113 on its surface away from the second chuck 12. The first binding groove 113 is used to bind the winding. The first chuck 11 also has a first arc-shaped transition portion 114 on its surface away from the second chuck 21. When using enameled wire winding, the first arc-shaped transition portion 114 helps to reduce the tension of the enameled wire winding at the bend and protect the enamel film on the surface of the enameled wire. The first chuck 11 has a first clearance groove 115 on its surface facing the first insertion portion 12. The first clearance groove 115 surrounds the first insertion portion 112. When the first winding frame 1 is inserted into one end of the iron core, the first clearance groove 115 ensures that there is still a gap between the first chuck 11 and the stator iron core, which can avoid interference during assembly.

[0021] In some embodiments, the first chuck 11 is provided with an inner wire baffle on the side near the stator core. The end of the inner wire baffle away from the second chuck 21 is arc-shaped, which can ensure that there is a certain creepage distance between the winding coil and the stator core, so that the winding frame is also suitable for high voltage type stator assemblies.

[0022] For the first connector 12 mentioned above, please refer to Figure 3 and Figure 4 The first plug-in portion is provided with a groove 121, which is disposed on the inner surface of the first plug-in portion 12.

[0023] For the second chuck 21 mentioned above, please refer to Figures 6-8 The second chuck 21 includes a second wire-concealing groove 211, a second outer wire-blocking plate 212, a second wire-binding groove (not shown), a second arc-shaped transition portion (not shown), and a second clearance groove 213. The second wire-concealing groove 211 is disposed between two adjacent second insertion portions 22. The second wire-concealing groove 211 is used to accommodate the winding cable. Accommodating the winding cable in the second wire-concealing groove can prevent it from encroaching on the stator space during wire binding. The first chuck 11 extends from the end away from the second chuck 21 with a first outer wire-blocking plate 112. The first outer wire-blocking plate 112 is provided with a plurality of first wire-passing grooves 1121. The first wire-passing grooves 1121 are used to accommodate the winding cable. During wire binding, the cable can be wrapped around the second wire-passing groove in an S-shape before binding, which helps maintain the tension of the binding wire. The second chuck 21 has a second binding groove on its surface opposite to the first chuck 11. The second binding groove is used to bind the winding. The second chuck 21 also has a second arc-shaped transition portion on its surface opposite to the first chuck 11. When using enameled wire winding, the second arc-shaped transition portion helps to reduce the tension of the enameled wire winding at the bend and protect the enamel film on the surface of the enameled wire. The first chuck 11 has a first clearance groove 115 on its surface facing the first insertion part 12. The second clearance groove 213 is arranged around the second insertion part 22. When the second winding frame 2 is inserted into the other end of the stator core, the second clearance groove 213 ensures that there is still a gap between the second chuck 21 and the stator core, which can avoid interference during assembly. In some embodiments, the side of the second chuck closest to the stator core has an inner wire baffle plate. The end of the inner wire baffle plate away from the first chuck is arc-shaped, which can ensure that there is a certain creepage distance between the winding coil and the stator core, so that the winding frame can also be used for high-voltage stator assemblies.

[0024] For the second connector 22 mentioned above, please refer to Figure 6 and Figure 7 The second plug-in portion 22 is provided with a groove 221, which is disposed on the outer surface of the second plug-in portion 22.

[0025] In this embodiment of the utility model, the winding frame includes a first winding frame 1 and a second winding frame 2. The first winding frame 1 includes a first chuck 11 and a plurality of first plug-in portions 12. The plurality of first plug-in portions 12 are fixedly spaced at the first chuck 11. One end of the first plug-in portion 12 away from the first chuck 11 is provided with a groove 121. The second winding frame 2 includes a second chuck 21 and a plurality of second plug-in portions 22. The plurality of second plug-in portions 22 are fixedly spaced at the second chuck 21. The second plug-in portion 22 is provided with a protrusion 221. One second plug-in portion 22 is inserted into the groove 121 of one first plug-in portion 12. By adjusting the depth of the second plug-in portion 22 inserted into the groove 121, the distance between the first chuck 11 and the second chuck 21 is adjusted, thereby adjusting the height of the winding frame. That is, by adjusting the height of the winding frame, when the first winding frame 1 and the second winding frame 2 are respectively inserted to both ends of the stator core, there is no gap between the stator core and the winding frame, and there is no need to insert insulating paper.
