Step 3: the direction of striding stator slot along a last step from the coil end of last step formation continues to stride the also rightabout coiling N1 circle formation tertiary coil of the last step coil-winding in edge of M stator slot;
Step 4: repeated execution of steps two and three, when the number of turns on presetting pilot trench reached the N1+N2 circle, flow process finished.
The above-mentioned pilot trench that presets can be the arbitrary stator slot on the stator core, and promptly the initiating terminal of winding can begin coiling from any stator slot of stator core.
Said preset direction is clockwise direction or counter clockwise direction.
Through said method of the present invention, solved motor windings and caused the end connecting line too concentrated along the single direction coiling all the time, skewness; Can not effectively utilize the stator core end space and cause the end winding size big, be difficult to satisfy the drawback of motor matching requirements, method for winding of the present invention has disperseed the end connecting line greatly; So not only make electric machine structure compact, be convenient to the motor assembling, and; Owing to reduced the end connecting line of adjacent windings; Therefore correspondingly reduce resistance, reduced the energy consumption that the heating of resistance causes, improved electric efficiency.
Fig. 1 is the coiling expanded view of prior art three phase electric machine winding, consults Fig. 1 and can know, is wound with three phase windings on the stator core of motor, and number of pole-pairs is 3, and coil 1 is striden 4 and is example, and existing is example with the A phase winding, describes its method for winding in detail.The coiling of the initiating terminal of A phase winding from the stator slot 1 of stator core clockwise around to stator slot 4; Repeat after the intact required number of turn, lead-out wire, repeats again after the intact identical number of turn 7 clockwise around to stator slot 10 along equidirectional from stator slot; Lead-out wire along equidirectional from stator slot 13 clockwise around to stator slot 16; Like cocycle, behind the stator slot of complete stator core, draw coiling A ' up to evenly and at intervals, promptly accomplish the coiling of A phase winding; The winding method of B phase winding and C phase winding is identical with A phase winding winding method, at this repeated description not.By on can know, three stator slots of being separated by between the adjacent coiling of each phase winding, i.e. coiling whenever from a coil around to its adjacent coil the time; One section end winding connecting line is left in the capital, like this, and along with the increase of coil quantity; The end winding connecting line is also many more, not only makes electric machine structure be difficult to satisfy the motor matching requirements, is not easy to the machine coiling; And, correspondingly reduced the operating efficiency of motor windings because increasing of coiling makes that the electric current under the same voltage has reduced.
