Abstract

Изобретение относитс к обмоткам электрических машин переменного тока с двум разнополюсными магнитными пол ми в общем магнитопроводе. Цель изобретени - расширение области применени обмотки путем получени чисел пар полюсов 9/6, а также улучшение параметров дл полюсности р. Обмотка выполнена из восемнадцати равномерно смещенных ка- тущек и соединена в три параллельные ветви, начала и концы которых образуют зажимы дл полюсности р , а выводы от их средних точек - дополнительные зажимы дл полюсности р . В первую ветвь включены последовательно катушки с номерами 1, 7, 13, -16, -10, -4, а дл двух других ветвей номера катушек чередуютс относительно первой ветви с интервалами в две (дл второй ветви) и в четыре (дл третьей ветви).катушки Указанные дополнительные зажимы выполнены от средних точек второй и третьей звезд, а шаг катушек по пазам равен полюсному делению дл полюсности р. Знак минус перед номером катушки означает ее встречное включение в ветви. 3 ил. (ЛThe invention relates to windings of electric machines of alternating current with two polarized magnetic fields in a common magnetic core. The purpose of the invention is to expand the field of application of the winding by obtaining the numbers of pairs of poles 9/6, as well as improving the parameters for polarity p. The winding is made of eighteen uniformly displaced grooves and connected in three parallel branches, the beginnings and ends of which form clamps for polarity p, and the leads from their midpoints - additional clamps for polarity p. In the first branch, coils numbered 1, 7, 13, -16, -10, -4 are connected in series, and for the other two branches, the number of coils alternate with respect to the first branch with intervals of two (for the second branch) and four (for the third branch ). Coils These additional clamps are made from the midpoints of the second and third stars, and the groove step of the coils is equal to pole division for polarity p. The minus sign in front of the coil number means its counter-inclusion in the branches. 3 il. (L
