In the accompanying drawings, function identical element is correspondingly provided with identical reference symbol.
Fig. 1 shows the stator 1 for motor.Stator 1 can be provided for the starter generator of such as motor vehicles.
Stator 1 has laminated core 2, and the laminated core can be in a way known per se by soft magnetic metal lamella (coercive force field strength
Degree be less than 1000A/m) formed, the soft magnetic metal lamella is electrically insulated from each other and axially 3 stacked or layered.
In the groove 4 of laminated core 3, in each case, two conductor elements 6,7 pass through axial notch opening
5 insertions.For clarity, in each case, only some specific elements are already provided with reference symbol.Each groove
4 conductor element 6,7 is arranged to align in radial direction 8, and one behind another.In each case, radial direction side
Pointed to vertically outward to 8 from the axis 9 so as to limiting axial direction 3.Axis 9 corresponds to the rotor that can be arranged in the stator
Expection rotation axis.
Different radial distances between conductor element 6,7 cause two rings or layer 10,11, wherein radially outer conductor element
6 forming layers 10 and the forming layer 11 of inner radial conductor element 7.Layer 10,11 is the part of the Double Layer Winding 12 of stator 1.Institute
In the example shown, Double Layer Winding 12 includes six electric coils, and each electric coil is the respective subset by connecting conductor element 6,7
It is and caused.In each case, a conductor element of a conductor element of outer layer 10 and internal layer 11 is formed in coil
One coil be connected (phase connection) or coil connection 13.The coil connection 13 of coil is each arranged in connection
In region 14.
For purposes of illustration, Fig. 2 shows single electric coil 15.The diagram that diagram in Fig. 2 corresponds in Fig. 1, wherein
Eliminate all that conductor element 6,7 associated with other electric coils.Coil 15 shown in Fig. 2 have altogether three circle or
Three circles 16, they connect 17 by linkage in join domain 14 and are electrically connected to each other.
In order to form the circle 16 of coil 15, circumferentially direction U1 is tilted or warpage for the conductor element 6 of outer layer 11, and
The conductor element 7 of the internal layer 11 warpage on relative circumferential direction U2.Therefore, the conductor element 6 of two layers 10,11,7 quilts
Interlocking, result are tilting zones with the inclination angle relative to end face 18.End conductor also has leads parallel to what axis 9 oriented
Body end portion.For this purpose, end conductor has skew.
The inclination angle of all tilting zones of end conductor is all identical.Therefore, these end conductors especially closely one
On top of the other.End conductor is the part on the winding head 20 on the end face 18 of laminated core 2.
Fig. 3 shows how electric with the soft magnetic metal lamella of laminated core 2 electrical conductive elements 6,7 in the inside of laminated core are
Insulation.For clarity, in each case, several reference symbols are provided just for the specified element in Fig. 3.Each conductor
Element 6,7 is formed by conductive bar 21 and electrical insulation parts 22.
Fig. 4 shows individually there is conductive bar 21 and the single electrical conductive elements 6,7 of electrical insulation parts 22 again.Each
In the case of, bar 21 can be tape conductor or flat conductor.The material of bar 21 can be such as copper.Electrical insulation parts 22
It is configured to sheath or hose element 23.
Fig. 3 shows how each bar 21 passes through the material and laminated core 2 of hose element 23 by means of insulation component 22
Electric insulation.Hose element 23 is formed by thermoplastic, and the thermoplastic can have such as polyamide and/or PPSU
And/or PPA.
Fig. 3 also showed that in the region on each winding head 20, as the interlocking shown in Fig. 1 or the result of warpage, each
How bar 21 is pressed against the groove walls 24 of corresponding recesses 4, and wherein bar 21 is mechanically supported or warpage.
The plastics of hose element 23 can be applied in bar 21 by means of extrusion molding.
For this purpose, it is directed across extrusion by each bar 21 or by being separated to produce the wire of bar 21
Arrange (not shown).Annular gap is located therein, and plastics are gone out with deformable or liquid or fluid state from the annular gap
It is existing.As a result, the flexible pipe rested on bar 21 or wire is generated.
Fig. 5 shows during bar 21 is produced from wire how this wire to be divided into bar length
25 bar 21.It can provide herein：Eliminated absolutely by removing the plastic insulation of hose element 23 from bar 21 to be formed
The end 26 of edge, result are that each hose element 23 has the insulated lengths 27 for being less than bar length 25.Bar length can example
Such as in the range of such as 8cm to 15cm.
How Fig. 6 displayings by means of hose element 23 surround bar 21 with plastics, and wherein have can be for hose element 23
Thickness degree or wall thickness 28 in the range of 0.1mm to 0.5mm.The edge 29 of bar 26 preferably have bent portion or
Radius of curvature 30 in the range of 0.5mm to 1.5mm.This produces advantages below：During vibration movement edge 29 will not cut or
Tear hose element 23.
The external diameter 32 (that is, external diameter 32 of the hose element 23 in circumferential direction U1, U2) of conductor element 6,7 is than this
The small at most 0.2mm of recess width 33 on individual direction.Hose element 23 preferably contacts with two groove walls relative to each other.
How Fig. 7 displayings by means of stator 1 can obtain motor 34.In the case of motor 34, rotor 35 is rotatable
Ground is arranged in stator 1.Rotor 35 is connected in a rotationally fixed manner to axle 36.Motor 34 may be mounted at such as motor vehicles
In 37.Motor vehicles 37 can be such as automobile, specifically, passenger car or truck.Axle 36 can be connected to vehicle part 38,
The vehicle part can be such as pump of explosive motor or the hydraulic braking circuit for BAS.Can be with
Per se known manner by means of inverter by alternately making the electric coil of stator 1 be powered come motor 34.This is in stator
Inside produce rotating excitation field, this field drives rotor 35.Rotor 35 then rotates around axis 9.
Generally speaking, example shows that the electricity for the copper cash rod that how can obtain stator by extruding the plastic coating of application is exhausted
Edge.The thickness of plastic layer can optionally be set by certain way so that the pin of extrusion or the bar of extrusion can be inserted directly
Enter into the groove 4 in laminated core 2 and then interlocked or warpage or distortion.The advantages of better than prior art, exists
In the high cost process of groove insulation can be eliminated.Specifically, it is not necessary to put insulating paper in a groove and then with leaching
Stain resin carrys out varnish(ed) paper.Another advantage is that any one of insulating surface coating on insulating paper or bar is not
It can be damaged.
The hose element being made up of thermoplastic is flexible, and the shape with bar during warpage or distortion is fitted
Match somebody with somebody.The hose element being made up of plastics also has enough mechanical load-bearing capabilities, and nevertheless, can still select sufficiently thin
Plastic coating.
Therefore, the overall cost reduction saved and be associated be present in manufacturing step or processing step.Furthermore, it is possible to
Relatively short time cycle manufacture stator 1.With and with electric insulation face coat and subsequently, by means of insulating paper cast multiple
Compound compares the face coat for the bar 21 that bar is fixed in groove 4, and the plastic coating by extruding application, which has, to be changed
The mechanical load-bearing capability entered.
Therefore, example totally show the present invention how to permit tape conductor thermoplastic sheath be used for manufacture motor around
Group.
