The promotion of power density.With the development of flat wire insulation technology, the resistance to voltage levels of flat wire itself are continuously improved, and are originally used for 48V
The flat wire winding technique of automobile current generator gradually starts the driving motor neck for the new-energy automobile that voltage class is several hectovolts
Domain.
To improve potential waveform, motor is typically designed as distributed winding, i.e. MgO-ZrO_2 brick q >=2, phase each in this way
The each pair of of band extremely has down q coil.In existing flat wire winding construction, the levels end bay number of stator slots phase of each coil
Deng only (or several) stator slot of artificial short distance (or long away from) when needing to avoid being closed.In such winding construction, no
By being insertion side or weld side outlet from stator, remove the special-shaped lines such as lead-out wire and wire jumper, be left two to three kinds it is main
Coil form, one of which quantity is most in these main coils, another or two kinds of quantity are seldom, these types of coil institute
Differed greatly with quantitative proportion.Such as to realize that 60 slots, number of pole-pairs 5, the winding construction per 4 layers of slot conductor number, every branch contain
Standard " u "-shaped coil 18：Wherein there are 16 across 6 stator slots, there are 2 across 5 stator slots, the two ratio is 8：1.
Since flat wire winding needs to use equipment pre-formed, a problem is brought in this way：It needs to make more work when making coil
It fills or configures more equipment to go to make the more coil of requirement, certain producing line production is caused to be critical and other producing line
Idle situation occurs.
Moreover, flat type copper wire is at least needed from during straightway is shaped to " u "-shaped coil in the top bending part of coil
It bends twice, flat copper line insulating layer has damage.The winding mode of the prior art, coil non-solder end winding overhang length one
It causes, each coil causes end turn space nervous, can exist in motor During Process of Long-term Operation in end " laminating " arrangement mutually
The risk of short circuit due to insulation breakdown.
Invention content
It is an object of the invention to overcome at least one defect of existing motor, a kind of flat wire stator winding of motor is provided
Structure solves the most span of dosage in the prior art mainly under the premise of conductor in ensureing slot is constant by Lithofacies dividing
