The invention relates to the technology of winding electrical machines and can be used in the manufacture of single-layer windings of smooth (.base) Korea. There is a known method of laying a two-layer winding of smooth koreas by successively superimposing the lower and upper layers of the winding sections on the core, followed by fixing them with the help of technological wedges of HP. The disadvantage of this method is that it takes a lot of time to perform the winding laying operation due to the complexity of installation and the removal of large wedges. The closest to the invention to the technical essence and the achieved result is the method consisting in laying the lower and upper layers of the winding sections on the core, pre-artery fixation of clamping elements and final fixing them with a bandage 2. The disadvantages of this method are low productivity of work when laying the winding core of rigid sections and low coefficient of copper filling of the winding space. The purpose of the invention is to increase labor productivity and increase the filling ratio of the winding space of the media. This goal is achieved by installing a two-, stepped cylinder with grooves on the forming surfaces and clamping elements located in the grooves of the larger cylinder step, prior to application of the coils at the end of the core, on the side opposite the manifold, movably in the axial direction, and the preliminary fixation are installed by installing the front parts of the coils in the slots of the lower stage and T1 displacement 3. 9 clamping elements along the core axis. 1 shows a core core with a cylinder installed at its end; figure 2 is an end view of the cylinder; on fig.Z - heads coils, laid in the grooves of the cylinder; 4 a core with the coils fully laid and fixed. The method is carried out as follows. from the end of the core 1, on the side opposite to the collector, install a two-stage cylinder 2, which has on the forming surfaces grooves 3 in the form of a dovetail, evenly spaced around the circumference of a greater degree; and grooves H around the circumference of a smaller step. The number of slots k is equal to the number of coils. The 8 grooves 3 of the larger cylinder stage are fitted with clamping elements 5, which are axially movable and made in the form of a shank entering the groove and protruding arcuate segments. Before laying the coils 6, the clamping elements are set to their extreme positions. The coils are mounted on the receiver, the factory frontal part 7 in the groove k is placed interlayer insulation 8 and fixed by moving the clamping elements along the axis of the core. After the coil is secured in the slots of the collector, it is finally fixed in the active part by means of a bandage. Then they move the latches, remove the cylinder and transfer the core with the coils to subsequent operations. The efficiency of using the method is to increase labor productivity by using a simpler technological device and to increase the filling ratio of the winding space with copper. The invention of the method of laying a single-layer winding of smooth Korean electric machines by applying winding coils to the core, pre-fixing them with clamping elements and finally fixing a bandage on the core, characterized in that, in order to increase labor productivity and increase the filling ratio of the winding space with copper, before applying the coils at the end of the core from the side opposite to the collector, install a two-stage cylinder with grooves on the forming surface and clamping elements arranged in the slots more stage cylinder movably in the axial direction, and the provisional fixing is performed installing the coil ends in the coil slots at stage and it peremescheni- clamping elements along the axis of the core.
