The plurality of tooth upper insulations 11 are distributed around the yoke upper insulation 13, and the tooth yoke connection upper insulation 12 is respectively connected to the yoke upper insulation 13 and the tooth upper insulation 11. Specifically, the yoke upper insulation 13, the tooth upper insulation 11, and the tooth yoke connection upper insulation 12 can be respectively covered on the yoke 41, the tooth 42, and the tooth yoke connection 43 in the stator core 40 to achieve an insulation effect.

[0043] Furthermore, combined with Figure 1 , at least one of the upper insulators 11 of the tooth portion includes a first fixing platform 110 and a first positioning portion 111. The first fixing platform 110 has a pin fixing hole 101, and the pin 30 can be inserted into the pin fixing hole 101, thereby fixing the pin 30. The first positioning portion 111 is connected to the first fixing platform 110. The first positioning portion 111 is used to connect other components of the stator assembly 100, wherein the "other components" refer to components connected to the upper insulating frame 10, for example, the "other components" can be a pin fixing plate for positioning the pin, a bearing seat for installing the bearing, etc. According to different models or types of stator assemblies 100, the "other components" are adjusted accordingly. It can be understood that the first positioning portion 111 connects other components of the stator assembly 100 to connect the stator assembly 100 into an integral structure.
