Abstract

Изобретение относитс к электротехнической промьппленности и может быть использовано при изготовлении электрических машин. Целью изобретени вл етс улучшение качества за счет увеличени коэффициента заполнени паза и исключени электрического пробо изол ции. Способ укладки обмотки в пазы магнитопровода эл. машины осуществл етс следующим образом . Обмотку, состо щую из секций, охватывающих один или несколько зубцов магнитопровода, раздел ют на две части, имеющие аналогичные схемы намотки , так, чтобы их сумма быпа равна сумме витков тех же секций заданной обмотки. Укладку каждой катушечной группы (КГ) секции осуществл ют одним и тем же проводником в обеих част х КГ. Укладку в первой части КГ производ т от центра к периферии, а во второй - от периферии к центру. Затем КГ располагают послойно, начи- на с нижней и укладыва затем после- дующие катушечные группы, а концы проводников внутренних витков катушек вывод т вдоль оси магнитопровода. Отсутствие пересечени выводов КГ с витками исключает пробой изол ции. (ОThis invention relates to electrical industry and can be used in the manufacture of electrical machines. The aim of the invention is to improve the quality by increasing the filling ratio of the groove and eliminating electrical insulation breakdown. Method of laying the winding in the slots of the magnetic circuit of the el. machine is as follows. The winding, consisting of sections covering one or several teeth of the magnetic circuit, is divided into two parts having similar winding patterns, so that their sum is equal to the sum of turns of the same sections of the given winding. Laying of each coil group (CG) of the section is carried out by the same conductor in both parts of the CG. Laying in the first part of the CG is produced from the center to the periphery, and in the second - from the periphery to the center. Then the CGs are placed in layers, starting from the bottom and then the subsequent coil groups are laid, and the ends of the conductors of the inner turns of the coils are drawn along the axis of the magnetic circuit. The absence of intersection of the conclusions of the CG with the turns eliminates breakdown of isolation. (ABOUT
