DC MACHINE ANCHORS

The invention is based on the technology of single-layer windings of coreless cylindrical cores of direct current machines and can be used in the electrical industry.

Known sposbb manufacturing winding, unplugged core of an electric machine, in which the winding workpiece is obtained by winding a wire onto a turn pattern to a turn, fastened with technological tapes, and after removing the workpiece from the pattern these leit.y are cut into pieces carrying the two conductors adjacent sections, so that the cut on one side corresponds to the middle of the part on the opposite side. After forming the winding by repeatedly circumventing the core, the active layer is filled with copper winding and fixed by compounding {.

The disadvantage of this method is the large labor intensity due to the successive installation and gluing of the active side of each elementary section.

The closest to the present invention is a method of manufacturing a winding of the electric core of an electric machine, according to which the winding of the core is manufactured from one or several (depending on the number of parallel conductors) wires that are wound 5 roundly wound by turn to turn a special pattern and are placed along the length of the pattern at a distance corresponding to the unfolded length of the circumference of the core. The parts of the winding soldered to the collector are made in the form of loops formed

The coil is pressed against the core by an insulating strip by rotating the core and due to the tension created by the tension device. After that, measles is impregnated or compounded With subsequent crimping and baking in a special mold 2. The disadvantage of this method is that it is impossible to manufacture a single-layer winding, since with continuous winding of the winding billet a coil to a coil and subsequent unfolding of the billet with a shift less than the template diameter, it is impossible to form a winding into one layer. If the value of the shift is set equal to the diameter of the diam., Then in this case it is possible to stretch and then form the winding into a flat ribbon with one layer. However, the total length of the molded winding will either be much longer than the length of the core circumference and when laying it on measles it will wrap more than one layer or equal to the circumference, but in this case the coil laid on the measles will not provide a diametrical arrangement. sections of the winding, which would entail a violation of the electrical circuit of the core and, as a consequence - the impossibility of the motor in a given mode. The purpose of the invention is the expansion of technological and logical capabilities by ensuring the manufacture of a single-layer winding. The goal is achieved in that according to the method, the winding of the workpiece is carried out with a step equal to twice the width of the winding sections, and the forming of the workpiece is carried out by inserting parts of sections of one side of the workpiece into intersection grooves of the other side, while inserting parts of sections of the ends of one side of the workpiece into intersection grooves of the ends the other side lead during the laying of the workpiece to measles. FIG. 1 shows a template with a wound workpiece; in fig. 2 is a section A-A in FIG. one; in fig. 3 shows the step of forming a blank into a flat ribbon; FIG. 4 shows the step of laying a piece of measles. The manufacture of a single-layer winding of a gapless core is carried out as follows. First, wire 1 is wound on the template 2 with a step equal to twice the width of section 3. The total winding length is determined by the diameter of the core 4 and is equal to the length of the circumference passing through the center of the wire 1 laid on the measles 4. On each section 3, conclusions 5 are made in the form of loops, by pulling the wire 1 onto the rod 6 of the template 2. During winding, the active parts of section 3 are fastened with insulating tape 7, while on one side of the template 2, the leute 7 is placed under sections 3 on one half of the total winding length, and in the second half - over sections 3. On the opposite On the opposite side of the template 2, the tape 7 is placed oppositely, i.e., first over sections 3, and then under sections 3. Then, the winding 8 is removed from the template 2 and molded, simultaneously shifting by a distance equal to half the circumference of the core 4 (schag winding). In this case, sections 3 of one side of the workpiece 8, along the active part, are inserted into intersection grooves 9 of the other side until the winding is in the form of a flat tape. After that, the winding blank 8 is placed around the core 4, inserting sections 3 of one end of the winding blank into intersection grooves 9 of the second end. The winding is fixed on the bark 4 and the frontal parts are molded. Then the bark 4 with the winding is impregnated with an electrically insulating compound and polymerized in the mold. The proposed method allows one-layer windings to be produced for baseless DC machines of direct current. This method is easy to mechanize, which will increase productivity and improve working conditions. The invention The method of manufacturing a winding of a non-core core of a direct current machine, comprising winding the winding billet on a template, fastening the turns of the active part of the winding. reeling, forming the blank into a flat tape with a shift to the winding core and laying the workpiece to a measles, characterized in that, in order to expand technological capabilities by ensuring the production of a single-layer winding, the winding of the blank is carried out in steps equal to twice the width of the winding sections forming the billet is carried out by inserting parts of sections of one side of the billet into intersection grooves of the other side, while inserting parts of sections of the ends of one side of the billet into intersectional grooves of the ends of the other side lead to about the time of laying billet measles.
