The invention relates to the technology of manufacturing electrical machines and can be used in the manufacture of machines with disk bark.

The purpose of the invention is to improve the quality due to the uniformity of winding.

 Figure 1 shows a template with a winding preform wrapped around it; figure 2 - the location of the blanks around the circumference before laying in the disk; on fig.Z - the process of winding sections sequentially, one for each template located around the circumference.

The method is carried out as follows.

After winding, the coils are fixed against displacement. All P templates with wound blanks have a circumference (figure 2), between the first template and the second template 4, between the second template 4 and R-m template 5 Central

winding sections 2 are wound sequentially around the circumference, moving from one pattern to the next one after winding each section, the terminals are simultaneously executed, the turns are fixed from the displacement and the patterns are removed. Next, flat rings are attached to the frontal parts of the blanks and these rings are turned relative to each other by a step of the winding with simultaneous approach. In this case, the winding is laid in the plane. Then connect the leads to the current collector.

Another solution is also possible, in which, after positioning the templates around the circumference and winding the sections, the winding is laid in the plane using flat rings at the same time as removing the blanks from the templates. In this case, when turning the rings, the templates are gradually squeezed out into the slots located on the rings.

Thus, the proposed method improves the quality of the wave windings of electric machines due to the homogeneous laying of the turns around the core, which eliminates overlaps and, consequently, damage to the insulation of conductors. The use of such windings leads to an increase in the reliability of electrical machines.
