Description

The stator winding of cylinder submersible linear electric machine with oil and winding method thereof

Technical field

The invention belongs to the stator winding and the winding method thereof of a kind of parts of reciprocating type oil immersion line motor, particularly a kind of cylinder submersible linear electric machine with oil.

Background technology

Its coil of existing cylinder submersible linear electric machine with oil adopts round cross section electromagnetic wire, along a direction coiling, lead-in wire comes from inside and outside both sides, particularly inboard lead-out wire must cause the outer end and be connected with another coil, so lead-out wire will be across winding, thereby requires to increase insulation system, will take volume like this, in the confined space, influence the sectional area of lead, in oil well casing,, therefore can not realize high-power lifting because the space is little.

Summary of the invention

The stator winding and the winding method thereof that the purpose of this invention is to provide a kind of cylinder submersible linear electric machine with oil, the winding structure uniqueness of coil, lead-out wire does not take volume, does not influence the sectional area of lead, improves the lifting force of linear electric motors to greatest extent.

The stator winding of cylinder submersible linear electric machine with oil provided by the invention, it comprises the stator coil winding, it is characterized in that: the stator coil winding is to be made of a plurality of single cake coil polyphones, the two ends lead-out wire of each single cake coil all is arranged on outside the circle, each single cake coil is the double-layer coil structure, one deck coil is clockwise winding structure, and another layer line circle is counterclockwise winding structure.

The electromagnetic wire that above-mentioned stator coil winding adopts is flat type electromagnetic wire.

The winding method of stator winding is: at first determine electromagnetic wire length by the length of run of a plurality of coils of stator winding, elder generation's coiling head end list cake coil, draw back half of head end list cake coil total length and added line length that S is set is curved, as the coiling starting point, from inside to outside divide two-layer coiling with counter clockwise direction in the direction of the clock, the two ends lead-out wire is all around to circle, the head end lead-out wire is link of stator winding, other end lead-out wire carries out the continuous coiling of next single cake coil, method is the same, each single cake coil of coiling finishes until the whole coilings of electromagnetic wire by that analogy.

Advantage of the present invention is: 1, the winding structure uniqueness of stator coil, two ends lead-out wire place the coil outside, and lead-out wire does not take volume, has increased the power of linear electric motors.Improve the lifting force of linear electric motors to greatest extent.2, coil is selected the coiling of flat type electromagnetic wire for use, makes full use of dish-type iron core space, improves the motor copper factor to greatest extent, thereby has also improved the sectional area of electromagnetic wire, reduces the reactive loss of motor.3, make cake molded lines circle and dish-type iron core have the tight of maximum area to contact; every circle electromagnetic wire all has a side closely to contact iron core; help to outside heat conduction; guarantee on the one hand when sense of current moment change; avoid the vibrations of coil; again for electromagnetic wire provides good radiating condition, effectively protected the insulating barrier of lead simultaneously on the other hand.

Embodiment

See Fig. 1,2, stator winding concrete structure provided by the invention following (this example is the wherein phase winding in three phase windings): the electromagnetic wire that the stator coil winding adopts is a flat type electromagnetic wire.The whole winding winding is provided with a plurality of single cake coils 1, and the two ends lead-out wire of each single cake coil 1 all is arranged on outside the circle, and each single cake coil 1 lead-out wire polyphone (being the line 4 excessively that connects between each single cake coil).Each single cake coil 1 is a double-decker, and one deck coil 2 is clockwise winding structure, and another layer line circle 3 is counterclockwise winding structure.One deck coil 2 clockwise coiling directions are converted to another layer line circle 3 counterclockwise coiling directions, and at inner ring starting point place S to be set curved, and its structure is seen shown in Figure 3.

The winding method of coil is as follows:

Electromagnetic wire adopts a flat type electromagnetic wire, at first determine electromagnetic wire length by the length of run of a plurality of coils of winding, carry out the coiling of head end list cake coil 1 earlier: draw back half of head end list cake coil 1 total length and added line length that S is set is curved, as the coiling starting point, from inside to outside divide two-layer coiling with counter clockwise direction in the direction of the clock, the two ends lead-out wire is all around to circle (referring to Fig. 1-3), the head end lead-out wire is link of this winding, other end lead-out wire carries out the continuous coiling of next single cake coil, winding method is identical with head end list cake coil, that is: draw back half of second single cake coil 1 total length and added line length that S is set is curved, as the coiling starting point, from inside to outside divide two-layer coiling with counter clockwise direction in the direction of the clock, each single cake coil 1 of coiling finishes until the whole coilings of flat type electromagnetic wire by that analogy.
