Description
Technical field
The present invention relates to a kind of stator structures of motor, and in particular to the flat wire motor stator knot as made of flat type copper wire coiling
Structure.
Background technique
Flat wire motor should be successfully applied in multiple industrial circles such as water power, wind-powered electricity generation, in recent years, with new-energy automobile
Market, which is flutterred, opens up and technological break-through, flat wire motor also in being applied in new-energy automobile drive area gradually, flat wire motor compared with
Traditional round wires motor has higher power density, and unfailing performance is more preferable, and failure repair rate is lower.Currently, in foreign countries with general
It is sharp this, the new-energy automobiles advanced enterprises such as tesla, successfully by flat wire motor application to the vehicle of oneself, and successfully
Realize industrialization.At home, each enterprise of China is also in largely deposit flat wire motor the relevant technologies and technological ability.
But due to flat wire motor use flat copper wire material carry out winding technique, in manufacturing process still have compared with
High technical difficulty.Especially in winding solder joint junction, more flat type copper wires at butt welding point is needed to be bent in various degree,
Bending difficulty is big, and short time consumption is long, while can also seriously damage the original insulation of flat type copper wire and copper wire performance.
Summary of the invention
For above the shortcomings of the prior art, the present invention provides a kind of stator mechanisms of horizontal flat wire motor, use
Busbar connector, at order and winding solder joint flat type copper wire assigned, spot welding two procedures, the electrical connection of winding solder joint can be completed.
To achieve the above object, the technical scheme is that
A kind of stator structure of flat wire motor, including stator core, stator winding and outlet terminal, stator winding is using flat
Copper wire carries out coiling, it is characterised in that further includes busbar connector, busbar connector is fixed at winding welding point, is electrically connected with solder joint
It connects.
The busbar connector is made of insulator foot and copper bar, in the direct jack to insulator foot of copper bar.
The insulator foot is curved groove structure, and radian is consistent with motor stator radian.Outside insulator foot inner arc
Equipped with assigning slot, slot insied width and machine winding flat type copper wire equivalent width.
The copper bar is arcuate structure, and radian is consistent with insulator foot.Copper bar is made of copper bar main body with protrusion, protrusion
Positioned at the upper end of copper bar main body, protrusion is electrically connected with winding solder joint.
The cross-sectional area of copper bar main body and protrusion is not less than the cross-sectional area of stator winding flat type copper wire.Raised institute is in place
It sets and assigns the leading-out terminal of slot, winding solder joint in same perpendicular with insulator foot.
Compared with prior art, the present invention has significant advantages and beneficial effects, is in particular in:
1, using busbar connector, the bending technique of more flat wires is avoided, production ease is improved；
2, the bending of flat wire is avoided, to reduce the damage bent to flat type copper wire exterior insulation and inner conductor；
Detailed description of the invention
Fig. 1 is flat wire motor stator structure figure
Fig. 2 is busbar connector copper bar structure chart
Fig. 3 is busbar connector insulator foot structure chart
Specific embodiment
Specific implementation method of the invention is as follows:
As shown in Figure 1-3, a kind of stator structure of flat wire motor, the stator core 1 made of magnetic links, flat type copper wire coiling
Stator winding 2, copper outlet terminal 6 and busbar connector 3 form, stator winding carries out coiling, copper wire cross section using flat type copper wire
Product determined by motor rated power and size of current, busbar connector 6 is fixed at winding solder joint, with solder joint by way of soldering into
Row electrical connection.
Busbar connector 5 is made of insulator foot 3 and copper bar 4, and insulator foot 3 is polyethylene material, and copper bar 4 is brass material,
4 jack of copper bar is inside insulator foot 3.
The generally curved groove structure of insulator foot 3 insulator foot groove 10 and assigns slot 9 by insulator foot shell 11
Composition assigns the flat of the insied width of slot 9 and stator winding 2 wherein assign on the inner arc outer wall of 9 committee member's insulator foot shell 11 of slot
Copper line width is consistent, thus guarantee assign slot 9 can the flat type copper wire by way of assigning with electronics winding 2 fix.
Copper bar 4 is similarly arcuate structure, and radian and insulator foot 3 are consistent, and cross-sectional area is not less than 2 flat type copper wire of stator winding
Cross-sectional area.Copper bar 4 is made of copper bar main body 7 and protrusion 8, and the cross-sectional area of copper bar main body 7 and protrusion 8 is not less than stator
The cross-sectional area of the flat type copper wire of winding 2.The outlet for assigning slot 9,2 solder joint of stator winding of raised 8 positions and insulator foot 3
End is in same perpendicular.
It assigns slot 9 that three, 8 setting three of copper bar protrusion are set altogether, and assigns slot 9, copper bar protrusion 8 and stator winding 2
Solder joint corresponds respectively, mutually compact, and is electrically connected by way of soldering.
For for exemplary embodiment of the invention, it should be understood that be in the protection scope of claims of the present invention
A certain kind demonstrative example therein has the guiding effect that those skilled in the art are realized with corresponding technical solution, and
Non- limitation of the invention.
