Abstract

The invention belongs to the technical field of motors and particularly relates to an S-shaped ranking and winding process of a high pressure stator coil. The S-shaped ranking and winding process of the high pressure stator coil comprises the following steps of 1, conducting pre-preparation on coil winding; 2, fixing an initial section of a coil and winding a first turn; 3, winding a second turn to a Nth turn, namely using a reversing tool to reverse a wire on the end portion of the first turn, winding the second turn on a winding former close to the first turn, winding a third turn on the second turn, using the reversing tool to reverse a wire on the end portion of the third turn, winding a fourth turn on the first turn, and sequentially winding until the regulated Nth turn is wound; and 4, tightening the tail end of the coil and cutting off. The S-shaped ranking and winding process solves the problem of coil turn explosion, coil turn position displacement and uneven ranking and the like due to the fact that width of the coil wound when the existing high pressure stator coil adopts an N-rank winding mode is smaller than one.

Description

High-tension stator coil S type is arranged and technique for coiling

Technical field

The invention belongs to technical field of motors, be specifically related to high-tension stator coil S type and arrange and technique for coiling.

Background technology

Now present, the high-tension stator coil coiling mostly adopt N arrange sub-thread connect around method carry out, the method for this coiling is very simple, also can solve the problem that coil replaces at lead-out wire.Yet, for the wire gauge flakiness ratio less than 1 coil, if adopt the N-type transposition, then being easy to occur in rise type and trimming the quick-fried circle of coil, wire turn alters the position and arranges unequal problems, have a strong impact on the quality of motor, increase to a great extent the production cost of enterprise, be unfavorable for very much the long-run development of enterprise.

Summary of the invention

Purpose of the present invention: adopt N to arrange winding method to alter the position and arrange unequal problems at the quick-fried circle of coil, wire turn that the coiling flakiness ratio occurs during less than 1 coil, arrange and technique for coiling and propose high-tension stator coil S type in order to solve existing high-tension stator coil.

Technical scheme of the present invention: high-tension stator coil S type is arranged and technique for coiling, may further comprise the steps:

Step 1: prepare before the coil winding;

Step 2: first section fixing and coiling the first circle of coil;

Step 3: the second circle to the N circle coiling, namely the end position utilization commutation instrument at the first circle commutates line, near the first circle coiling second circle on winding former, coiling the 3rd circle on the second circle, end position utilization commutation instrument at the 3rd circle commutates line, coiling the 4th circle on the first circle, coiling is gone down until around the N circle to regulation successively;

Step 4: tighten the coil tail end and cut off.

High-tension stator coil S type of the present invention is arranged and technique for coiling, utilized preferably the arrangement position of wire turn, the bar insulation that does not need again treatment coil, arranging the coil technique for coiling with existing N compares, this S type arrange and technique for coiling more simply, also economical with materials more, also solved simultaneously because of the wire gauge flakiness ratio less than 1 be difficult to adopt N to arrange and carry out sub-thread connect around the coil processing problems, greatly improved the quality of motor, save to a great extent the production cost of enterprise, be very beneficial for the long-run development of enterprise.

Further, in the described step 3, before commutation, the wire gauge of commutation place is taked partly repeatedly to wrap one deck 6050 poly-rare imines films.

6050 gather the use of rare imines films, can strengthen the wire gauge dielectric strength of commutation place.

Description of drawings

Fig. 1 is that stator shape circle N-type is arranged and the winding structure schematic diagram in the prior art;

Fig. 2 is that high-tension stator coil S type of the present invention is arranged and the winding structure schematic diagram.

Illustrate: 1,2,3 among Fig. 1 and Fig. 2 ..., N represent the first circle coil, the second circle coil, the 3rd circle coil ..., N circle coil.

Embodiment

As shown in Figure 2, the invention provides high-tension stator coil S type and arrange and technique for coiling, may further comprise the steps:

Step 1: prepare before the coil winding;

Step 2: first section fixing and coiling the first circle of coil;

Step 3: the second circle to the N circle coiling, namely the end position utilization commutation instrument at the first circle commutates line, near the first circle coiling second circle on winding former, coiling the 3rd circle on the second circle commutates line coiling the 4th circle on the first circle at the end position utilization of the 3rd circle commutation instrument, coiling is gone down until around the N circle to regulation successively, in this step, before commutation, the wire gauge of commutation place is taked partly repeatedly to wrap one deck 6050 poly-rare imines films;

Step 4: tighten the coil tail end and cut off.

In the present embodiment, step 3 is extremely important, takes full advantage of the arrangement position of wire turn, the bar insulation that does not need again treatment coil, not only simplify the operation of coil winding, and saved bar insulation and processed needed human and material resources and financial resources, be very beneficial for the long-run development of enterprise.

In addition, polyimide film is a kind of novel high temperature resistant organic polymer thin film, be by pyromellitic acid anhydride and diaminodiphenyl ether in extremely strong property solvent dimethylacetylamide through polycondensation and salivate film forming, form through imidization again.Polyimide film is the present in the world best film class insulating material of performance, has good mechanical property, electrical property, chemical stability and very high radiation resistance, high temperature resistant and resistance to low temperature.In the step 3, before the commutation, the wire gauge of commutation place is taked partly repeatedly to wrap one deck 6050 poly-rare imines films, can greatly strengthen the wire gauge dielectric strength of commutation place, thereby improve the quality of motor.

Above-described only is preferred implementation of the present invention, should be understood that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
