Description
Technical field
The present invention relates to threephase asynchronous stator single layer winding technical field, particularly threephase asynchronous stator single layer winding is just being overlapped a winding and inserting method, is applicable to number of poles 2P=6, groove and counts the threephase asynchronous stator single layer winding that Z=36, parallel branch count a=1.
Background technology
At present, for the stator winding of middle-size and small-size threephase asynchronous, all extensively adopt single layer winding.This single layer winding can only be put the effective edge of a coil in each stator slot, the part that connects two effective edges after coil setting-in outside iron core two end slots, claim end winding or the end of a thread, as be applicable to number of poles 2P=6, groove and count the threephase asynchronous stator single layer winding that Z=36, parallel branch count a=1, its advantage is: do not exist interlayer to puncture, layer insulation, buried copper activity coefficient are not high.This single layer winding comprises coiling, rule, wiring, and its method for winding is: adopt by hand, held line before this by single line, or around a whole phase, but want many between every adjacent lines bag, around a circle, then cut off, each line Bao Jun has a stature, a tail; Its coil-inserting method is that single line bag, single line bag are by pitch 1-6 embedded groove; Its mode of connection is to connect after head and a string, tail and tail string, finally occurs six wire U1, V1, W1, U2, V2, W2.The number of poles 2P=6 providing as Fig. 1, groove is counted Z=36, parallel branch is counted the circular wiring schematic diagram of threephase asynchronous stator single layer winding of a=1, the head of first the line bag of U in the mutually U1 that goes out to go between wherein, the tail string of the tail of first line bag and the 4th line bag, and fix by pad A1, the head of the 4th line bag is gone here and there mutually with the head of the 7th line bag, and fix by pad A2, the tail of the 7th line bag is gone here and there mutually with the tail of the tenth line bag, and fix by pad A3, the head of the tenth line bag is gone here and there mutually with the head of the 13 line bag, and fix by pad A4, the tail of the 13 line bag is gone here and there mutually with the tail of the 16 line bag, and fix by pad A5, the head U2 that goes out to go between of the 16 line bag, equally, V mutually in, the head V1 that goes out to go between of the 3rd line bag, its tail tail, head's pad is respectively B1, B2, B3, B4, B5, the head of the 18 the line bag V2 that goes out to go between, W mutually in, the head W1 that goes out to go between of the 5th line bag, its tail tail, head's pad is respectively C1, C2, C3, C4, C5, the head of second the line bag W2 that goes out to go between.The deficiency of this coiling, rule, mode of connection is: the one, and complex process, cost are high; The 2nd, due in when coiling, many around a circle between two line bags, will by how during rule around a circle from centre, cut off, so increased the consumption of material; The 3rd, the lengthening of the end of a thread and the existence of pad, caused resistance increasing, thereby increased power consumption, also increased the heat of motor operation, affected the performance of motor.In order to change above deficiency, the inventor had once succeeded in developing " reversed wire embedding and wiring method of double layer winding of three-phase asynchronous motor ", and had obtained national inventing patent, and its patent No. is 200810138790.4, by anti-cover rule connection, realized the serial connection that part need not be welded.But this anti-cover rule only limits to one instead to be overlapped between interior adjacent lines bag mutually, in fact saved the serial connection of 1-4 in the same phase adjacent lines of two layer winding bag, still also there is part pad in online bag outside, is not in three-phase, so be not suitable for threephase asynchronous stator single layer winding rule.
Summary of the invention
The object of the present invention is to provide a kind of not only not need to around between a whole phase time adjacent lines bag, want many around a circle then by how around a circle cut off after rule again, make stator winding clean and tidy, attractive in appearance, save wire rod, reduce costs, raise labour efficiency, and realize line bag within and without all less than serial connection by just overlapping, all there is no pad, save wiring step, can reduce resistance, power consumption, temperature, be exclusively used in number of poles 2P=6, groove is counted Z=36, parallel branch is counted the threephase asynchronous stator single layer winding of the threephase asynchronous stator single layer winding of a=1 and is just being overlapped winding and inserting method.
In order to reach above object, the technical solution adopted in the present invention is: this threephase asynchronous stator single layer winding is just being overlapped winding and inserting method, comprise coiling step and rule step, in rule step, first determined caulking groove, No. 1 groove that groove over against upper line outlet is decided to be to motor stator shell, like this, make to go between U1, V1, W1, U2, V2, W2 all draw from the upper and lower line outlet of motor stator shell, it is characterized in that: described coiling step is:

(G), embed U the 3rd line bag mutually, and by just overlap W phase and V mutually the 3rd to the 6th line bag realize the U direct cross-slot of the 3rd line bag line mutually: No. 13 groove of empty motor stator shell (1); By U mutually in the 4th next circle of line bag solution be the line of the 4th line bag, by W phase, V mutually the 3rd to the 6th line bag from U coming to protheca below of the 3rd line bag that comprises line mutually, together with U mutually the 4th to the 6th line bag be successively placed on the right workbench (2) of motor stator shell (1); U is embedded in No. 14 groove of motor stator shell (1) on the lower floor limit of the 3rd line bag mutually, limit, upper strata embeds in No. 9 groove of motor stator shell (1) again; Line is direct cross-slot;
(H), embed the limit, upper strata of first line bag of U phase of slinging and the limit, upper strata of first line bag of W phase: last, to sling U to embed in No. 33 groove of motor stator shell (1) on the limit, upper strata of first line bag mutually, the W coming slinging is the limit, upper strata of first line bag mutually, because its end of a thread is on upper strata, embedded in No. 35 groove of motor stator shell (1), and the W1 that goes out to go between.
2. threephase asynchronous stator single layer winding according to claim 1 is just being overlapped winding and inserting method, it is characterized in that: described just cover refers to follows U phase, W phase, V phase rule order, the line bag of rule not by counterclockwise from line bag that will rule pass below middle part forward surface cover come.
