Armature winding.
Background technology
Flat type copper wire wave winding armature winding in the prior art, when every slot conductor number N=4 layer, often three-phase windings are selected
Connection type be：1,2 layers of composition, one branch（Internal layer）, 3,4 layers are an other branch（Outer layer）, two branch circuit parallel connections companies
It connects, is easy the presence of imbalance between such two branches, causes two branch temperature distributing disproportionations, internal layers higher than outer layer winding temperature
The problem of.
From motor wave winding principle it is found that when per slot conductor number N=2 layer, every branch has 3 intercoil connections, 1 asterism
Connection, 3 power outlets.Existing flat type copper wire wave winding motor, when every slot conductor number N=4 layer, two branch circuit parallel connections connect
When connecing, two branches one share 6 intercoil connections, 2 asterism connections, 6 power outlets, and these special-shaped wires have distribution and collect
In, the problem that structural wiring is complicated, batch production technique is bad.
Invention content
The purpose of the present invention is to provide a kind of improved flat type copper wire wave winding armature winding, described is this improved flat
Copper wire wave winding armature winding will solve temperature distributing disproportionation, intercoil connection and star between two branches of three-phase windings in the prior art
The technical issues of point connecting line and the distribution of three-phase lead-out wire are concentrated, wiring is complicated and batch production technique is bad.
The present invention this flat type copper wire wave winding armature winding, including four and the above even level wave winding structure, wherein
The flat type copper wire of each freedom four of every branch and the above even level is constituted, and the wave winding structure includes drawing line end and non-drawing
Leading-out terminal, is arranged pad on the extraction line end, and the non-extraction line end is U-shaped line, and the U-shaped line of non-extraction line end
Pitch is equal.
Further, the extraction line end winding overhang is using two kinds of different pitch connections.
The present invention compares with prior art, and effect is positive and apparent.The present invention provide a kind of flat type copper wire wave around
Group scheme, to realize when per slot conductor number of plies N=4,6,8,10 ... and parallel branch can improve armature winding when being even number
The uniformity of inside and outside layer improves ectonexine winding temperature inhomogeneities, improves the electricity function index of motor.Maximum feature
It is to eliminate flat type copper wire armature end-connections intercoil connection, only remaining power outlet and asterism connecting line, it is different to enormously simplify end
The topology layout of shape line reduces electric motor winding end bulk.The non-U-shaped line equal pitch of extraction line end simultaneously is easy to implement certainly
Dynamicization plug wire.

Specific implementation mode
Embodiment 1:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, this improved flat type copper wire wave winding armature winding of the invention, this implementation
Example illustrates by taking 54 slots, number of pole-pairs P=6, short distance Y1=8, every slot conductor number of plies N=4 as an example.Specific implementation mode is：
This improved flat type copper wire wave winding armature winding of the present invention is four layers of wave winding structure, winding leading-out wire end terminal
U1, U2, U3, U4, V1, V2, V3, V4 ... ... index number 1,2,3,4 respectively it is corresponding per slot in 1,2,3,4 layer of conductor, 1,2
Layer winding is identical with 3,4 layers of winding configuration, but the connection type of end connecting line is different.The winding changes existing pad
It is placed on the layout of the non-lead-out wire of winding, is changed to draw line end.The non-U-shaped string pitch of extraction line end of winding is equal (Y2=10), and U
Molded line shape is identical, is more easy to realize that volume production automates U-shaped line molding and automation plug wire.
The flat type copper wire wave winding does not use prior art（A branch is constituted by 1,2 layer（Internal layer）, 3,4 layers are
An other branch（Outer layer）, two branch circuit parallel connection connections）, be also two branches per phase winding, but every branch is by 1,2,
3,4 layers of flat type copper wire are constituted.
The measure is to every slot conductor number of plies N=4, and 6,8,10 ... and parallel branch when being even number, various stator and rotor slots cooperations
Be applicable in, and winding pitch be short distance, it is whole away from, it is long away from being applicable in.
Two parallel branches of U phase windings, one branch of U phases power supply is from terminal U1 into another branch is from X4 into then
According to winding current direction, respectively by wave in the form of by all conductor series connections.
Parallel branch 1：U1 is first from 2# slot first layers（Dotted line）Into then with the entrance 12# second layers of pitch Y2=10（It is real
Line）, first layer 20# slot (dotted lines are then entered with Y1=8）, 30# is sequentially entered with same rule, 38#, 48#, 1# ... are proper
It detours one week well, to avoid winding from being closed, and does not change the pitch for drawing line end, artificially drawing line end one slot of retrogressing
(pitch Y1=7) go out to be directly entered 1# slots, same the second circle of rule detour, third circle, from U2 after detouring in this way from 48# in this way
Go out, winding third layer is then entered from U3 with same rule, finally goes out to connect asterism from the 4th layer of U4.
Parallel branch 2：Enter from the 4th layer of (solid line) X4 of 1#, then with the rule of branch 1 from the 3rd layer of 11# slots (dotted line)
X3 goes out, then from the 1# second layers (solid line) X2 into finally going out to connect asterism from 11# first layers (dotted line) X1.
V phases, W phases are as U phase winding rules, and final principle expanded view is as shown in Fig. 1 and end connection figure 2.Finally will
Asterism line U4, V4, W4 connect into an asterism, and asterism line X1, Y1, Z1 are connected into another asterism.Three phase mains lead-out wire：
U phases:U1-X4, V phase：V1-Y4, W phase：W1-Z4；Adjacent intercoil connection is connected directly：U2-U3, V2-V3, W2-W3, X2-X3, Y2-
Y3, Z2-Z3, adjacent intercoil connection are in 2,3 layers of position in the same slot, do not need additional connecting line, be directly welded at one
It rises, draws line end in this way and be only left power outlet and asterism connecting line, enormously simplify the structure cloth of end special line
Office reduces electric motor winding end bulk.
