The advantages that good, is suitable as the production material of insulating part.
Preferably, complete stator will be spliced into specifically, phase around each stator teeth for making coil in the step 3
In adjacent two stator teeths：The protrusion of one stator toothholder is bonded with the groove of another stator toothholder.Pass through protrusion and groove
The mode of fitting is spliced, and simple and practicable and splicing gap is small.
Preferably, two neighboring stator teeth being connected as a single entity specifically, to adjacent by welding in the step 4
The splicing seams of two stator teeths carry out terminals fuse, and the length direction of splicing seams is parallel with axis stator, same splicing seams
At least two fusion points are set along stator shaft orientation, are had enough by multiple fusion point stators along the length direction of splicing seams
Bonding strength.
The beneficial effects of the invention are as follows：（1）Stator is welded after being spliced by modular stator teeth, each before welding
Stator teeth eliminates the reliance on high-precision automatic coil winding machine all around coil is made, cost-effective, and it is difficult to reduce stator manufacture craft
Degree；（2）Modular stator teeth can be more reasonably utilized stator space, and the inner space of motor is made further to reduce,
Achieve the purpose that reduce motor size；（3）Protrusion and groove cooperation, the splicing seams for making two neighboring stator teeth are small as possible, just
In follow-up welding.
