Abstract

Usage: in the technology of manufacturing electrical machines, in particular in the technology of manufacturing windings of disk drives of DC electric motors, sections of which are made of insulated wire. SUMMARY OF THE INVENTION: sections are wound onto a template, the cross section of which is an octagon, obtained from a rhombus by cutting off four isosceles triangles pairwise symmetric with respect to the diagonals of the rhombus, whose equal sides lie on the sides of the rhombus, after which the sections are removed from the template, bent along two parallel smaller diagonals of the initial rhombus, straight lines passing through the vertices of the octagon, so that the folding parts of each section are in parallel planes against each other They are installed on the disk of the magnetic circuit lapped one on top of the other and squeezed, fixing their position by gluing with an insulating base in a semi-solidified state, covering the surfaces of the magnetic circuit in contact with them. 2 ill.

Description

The invention relates to the technology of manufacturing electrical machines and can be used in the electrical industry.

The purpose of the invention is the expansion of technological capabilities by expanding the range of products and reducing its cost.

In FIG. 1 shows a template for winding flat sections and shows the ABCDEFGH section thereon; FIG. 2 - the location of the curved sections of the winding on the magnetic core.

The invention is carried out as follows.

Section 2 is wound onto template 1. The section of template 1 in the winding plane is the octagon ABCDEFGH, obtained from a rhombus truncated at the vertices by isosceles triangles pairwise symmetrical with respect to the rhombus engines. The flat section 2 is removed from the template 1 and bent along two parallel smaller diagonal of the initial rhombus with straight lines AD and ЕН so that the bent sections of the section are in parallel planes against each other. The end surfaces of the magnetic core 3 core, as well as its outer cylindrical surface, are insulated with a semi-solidified material. Preliminary00

lento-made sections 2 are mounted on the drive line 3 lapped one on top of the other and crimped, fixing their position by gluing with the semi-hardened state of the insulating base covering the surfaces of the magnetic conduit in contact with them 3. Method of manufacturing a disk core winding allows the use of a winding from an insulated wire, each section of which contains four active and four frontal parts located on the corresponding surfaces of the core disk, that is, due to the winding of sections on and a template having a cross-section in the form of a rhombus, truncated at the vertices by isosceles triangles, pairwise symmetrical with respect to the rhomba diagonals, and bending of the removed sections along two parallel smaller diagonals of the original rhombus are straight lines passing through the vertices of the octagon so that the foldable parts of the section turn out to be in parallel planes opposite each other, to expand technological capabilities by expanding the range of manufactured engines in the range of supply voltages, powers, rotational speeds nor eliminate the known drawbacks of anchor windings formed by stamping, but also reduce the volume of work involved in the orientation and assembly of coil sections in the respective planes, i.e. to reduce the cost of the armature due to the fact that otgi0

the parts of the sections that are turned out are parallel to each other, and before installing the sections and crimping them onto the corresponding surfaces of the magnetic conductor, insulating material in a semi-solid state is applied to fix their position.
