The insertion portion 332a of the second layer also with the insertion portion 331a ' configuration in pairs of the ground floor of the groove 35 that is positioned at the adjacent pole span of groove that is passed with insertion portion 332a.The 4th layer insertion portion 331b ' and the 3rd layer the insertion portion 332b that is positioned at the groove 35 of the adjacent pole span of groove that is passed with insertion portion 331b ' dispose in pairs.The end 332d of insertion portion 332a links to each other with the end 331d ' of insertion portion 331a ' in the axial outside of stator core 32 axial forward end.The end 331e ' of insertion portion 331b ' links to each other with the end 332e of insertion portion 332b in the axial outside of stator core 32 axial forward end.
The coupling part of the coupling part of end 331d ' and 332d and end 332e and 331e ' is arranged in stator core 32 radially, thereby forms the adjacent layer coil-end.In the case, the coupling part of end conductor can be not overlapping in the axial outside of stator core 32 axial forward end, thereby form the second coil-end 31b.
Here, the conductor 331 that comprises insertion portion 331a, 331b, coupling part 331c and end 331d, 331e is called as big portion section.The conductor 332 that comprises insertion portion 332a, 332b, coupling part 332c and end 332d, 332e is called as little section.
Big portion's section 331 and little section 332 are included in the basic portion section 33.Basic portion section 33 is arranged in the groove 35 in a particular manner, thereby forms the stator coil 31 around twice of stator core 32 turnover.But, form the portion's section of drawing lead of stator coil 31 and the return portion of first and second laps that are connected stator coil 31 and be included in the portion's section with given shape.Stator coil 31 comprises portion's section of 9 given shapes.By connecting first lap and second lap, just by connecting the coil-end that inner coil end and outer coil end just can form given shape.
To the manufacture process of stator coil 31 be described below.
At first, arrange that basic portion section 33 makes the return portion 331c of big portion section 331 pass through to the outside of the return portion 332c of little section 332.Before being installed to portion's section 33 in the groove 35, twist part section 33 makes insertion portion 331a and insertion portion 332a corresponding respectively in the ground floor and the second layer of groove (first groove) 35, and conductor 332b and conductor 331b are corresponding to respectively in third and fourth layer of another groove (second groove) 35 of the pole span of clockwise direction and first groove interval of stator core 32.Then, the parts 33 with distortion are inserted into the groove 35 from the axial rearward end of stator core 32.Like this, insertion portion 331a, 331b, 332a and 332b just are arranged in the groove 35 in the above described manner.
After insertion section section 33, will be from the end bent of portion's section 33 that the axial forward end of stator core 32 is stretched out.Specifically, the end 331d and the 331e of crooked big portion section 331 make end 331d circumferentially leave end 331e along stator core 32.The point place that each end 331d of big portion section 331 and 331e extend to groove 35 about one and half grooves that passed apart from portion's section 331.The end 332d and the 332e of crooked little section 332 make end 332d near end 332e.Each end 332d and 332e extend to the some place of about one and half grooves.
After having carried out above-mentioned steps, by welding, for example ultrasonic bonding, arc welding and soldering are electrically connected all sections 33 in the groove 35, the 4th layer end 331e ' and the 3rd layer end 332e.Similarly, the end 332d of the second layer and the end 331d ' of ground floor are electrically connected.When finishing above-mentioned steps and form all ends shown in Figure 4, just formed the second coil-end 31b of stator 2.
When the axial rearward end of stator core 32 is seen stator core 32, big portion's section 331 and little section 332 just are arranged to form shown in Figure 5.The longitudinal centre line L1 of the groove 35 that overlaps with the radius of stator core 32 and be approximately 90 ° from the angle theta 1 between the centre line L 2 of portion's section 331 that ground floor stretches out.The longitudinal centre line L3 of the groove 35 that overlaps with the radius of stator core 32 and be approximately 100 ° from the angle theta 2 between the centre line L 4 of the 4th layer of portion's section 331 of stretching out.Just, angle theta 2 is greater than angle theta 1.
Therefore, at return portion 331c, near the curve stator core 32 internal diameters is less than near the curve stator core 32 external diameters.The minimum diameter D1 of the first coil-end 31a is greater than the inside diameter Ds o of stator core 32.Near stator core 32 internal diameters position folds return portion 331c with respect to the internal diameter contact wire of groove 35 to the outside diameter of stator core 32.Arrange little section 332 in the same way.
In addition, minimum diameter D1 is greater than the outer diameter D r of rotor 3.The maximum outside diameter D2 of basic portion section 33 just the external diameter of the first coil-end 31a greater than the outer diameter D s of stator core 32.This has just reduced the interference of coil-end 31a and other parts.Therefore, reduced the height of coil-end.Because the interval between fan and the coil-end 31a increases, thereby also reduced the noise of fan.
The U-shaped lead that is used to form portion's section 331 and 332 can be made as shown in Figure 6.At first, long lead is cut into certain length and forms straight lead 100 (step 1).Then, straight lead 100 is arranged on the certain location, and it is bent to U-shaped (step 2) basically by downward (direction shown in the arrow A 1) mobile removable pin 210.Therefore, just make U-shaped lead 200 with return portion 202, first straight line portion 205 and second straight line portion 207.
Secondly, along continuous straight runs (direction shown in the arrow A 2) is moved into forming roll 212, thus a side of return portion 202 form with regard to depression sweep (big sweep) 204 (step 3), as shown in Figure 7.Return portion 202 has flat 206 in a side relative with big sweep 204.Here, big sweep 204 is called as first curved portion, and flat 206 is called as second curved portion.Return portion 202 is corresponding with return portion (coupling part) 331c, 332c.
The part of first straight line portion 205 is corresponding with the insertion portion 331b, the 332b that are arranged near in the groove 35 of stator core 32 external diameters.The part of second straight line portion 207 is corresponding with the insertion portion 331a, the 332a that are arranged near in the groove 35 of stator core 32 internal diameters.
Because the return portion 331c and the 332c of portion's section 331,332 have big sweep 204 that is positioned at stator core 32 outside diameters and the flat 206 that is positioned at internal side diameter, therefore, have improved the evenness of the first coil-end 31a inner rim.By this structure, coil-end 31a, 31b and cooling air the generating means for example interval between mixed flow fan 11 and the centrifugal fan 12 increase.Therefore, reduced the noise of fan.
In addition, the portion's section for all portion's sections 33 rather than given shape all is formed uniformly bending.In other words, portion's section 33 is made identical length (identical resistance).Therefore, can keep its generating effect.
In addition, because first curved portion 204 is provided with near the outside diameter of stator core 32, the maximum outside diameter D2 of the first coil-end 31a is greater than the outer diameter D s of stator core 32.By this structure, towards the internal diameter of the back end housing 4b of the first coil-end 31a internal diameter greater than preceding end housing 4a.And back end housing 4b is being provided with pore 42 on the position of the first coil-end 31a.Therefore, improved cooling performance.
Portion's section 33 has the cross section that is roughly rectangle at insertion portion at least, and therefore, the zone of the groove 35 that portion's section 33 is occupied increases.Therefore, can obtain higher energy output, reduce its size simultaneously.Because the air duct on centrifugal direction increases, and therefore, under the situation of same cross-sectional area, compares with the portion's section with circular cross section, has improved the cooling effectiveness of coil-end 31a.
By adopting U-shaped lead 200 to form stator coil 31, can produce stator 2 at an easy rate, and can reduce production costs.But the present invention is not limited to embodiment aforesaid and shown in the drawings, under the situation that does not break away from aim of the present invention, can also other variety of way realize the present invention.
For example, as shown in Figure 8, second curved portion 206 can be slight curving.U-shaped lead 200A has little sweep 208 in the side near stator core 32 internal diameters, has big sweep 204 in the side near stator core 32 external diameters.The curvature of first curved portion 204 is greater than the curvature of second curved portion 208.In order to make U-shaped lead 200A, in step 3, adopt two format rolls 212.Apply power by two format rolls 212 from the both sides of lead 200A and form first curved portion 204 and second curved portion 208.
The present invention can be applicable to the electric rotating machine of any kind of, and a kind of in the electric generator of vehicle just.
