Folding has the plumb joint of a 5mm-10mm, and the plumb joint is parallel with flat segments；As the complex root flat type copper wire of lead-out wire, in plumb joint
End re-extended 20mm or more, extraction the end of a thread as electrical connection.
A kind of stator structure, including above-mentioned winding flat type copper wire, stator core and slot paper uniformly divide on stator core circumference
It is furnished with stator slot, the slot paper is arranged in stator slot, and flat type copper wire and stator core is isolated；It is characterized by: stator slot is
Sulculus mouth structure；Flat type copper wire as winding has intermediate a flat segments and both ends bending section, and both ends bending section is towards Xiang Fanfang
To；It is bent with plumb joint again in the end of the bending section, both ends plumb joint is parallel with flat segments；The flat segments of the flat type copper wire
It is disposed in stator slot from small-rabbet, both ends bending section is in outside stator slot both ends, by the plumb joint and other stators at both ends
The plumb joint of flat type copper wire and neat rear welding, form electrical connection in slot.
The flat segments of stacked flat type copper wire are layered in the stator slot, the interlayer of flat type copper wire both ends bending section is placed in insulation material
Material.
The same groove layer position of stator slot is placed in two to three flat type copper wires, and two to three flat type copper wires side by side
The plumb joint at both ends is parallel-connection structure.
The utility model has the characteristics that design is unique, design is reasonable, compact-sized；Using the flat copper of both ends bending and molding
Line, molding making are easy, can directly be placed in from stator small-rabbet, solve the trouble of traditional hair clip winding wears groove, and keep stator
The characteristic of small-rabbet, reduces cogging torque；Moreover after the assembly of flat copper line winding group, it is not necessarily to hair clip winding overhang trimming, is subtracted
After few special equipment is put into, and flat type copper wire is placed in slot, adjustable position is gone back, higher copper factor is reached.
