AI Technical Summary
Existing modular stator assembly devices are prone to damaging the stator and the roundness of the splices is not high enough, making it difficult to meet high precision requirements.
The stator tooth block is assembled in a modular manner using precision-machined positioning and fixing blocks and rings. It is fixed without damage by magnets and achieves efficient transfer and positioning by welding the base.
It achieves high-precision and high-roundness stator splicing, avoids stator damage, simplifies the process, reduces costs, and improves production efficiency.
