Abstract

1. Обмотка двухполюсной трехфазной электрической машины с числом пазов z=18, с шагом y=1-10, с числом параллельных ветвей а=1 и соотношением числа витков соединенных в треугольник четных катушек к числу витков соединенных в звезду нечетных катушек, равным, включает в себя шесть одно-двухслойных двухсекционных цепных катушек с соотношением числа витков в однослойных секциях к числу витков двухслойных секциях, равным 2:1, выводы расположены на внешних сторонах катушек, отличающаяся тем, что четные и нечетные катушки уложены в развалку, а начала катушек одноименных фаз звезды и треугольника смещены на два паза (40 эл. град.).2. Обмотка по п.1, отличающаяся тем, что выводы четных катушек выполнены на внутренних сторонах катушек.3. Обмотка по п.1, отличающаяся тем, что выводы нечетных катушек выполнены на внутренних сторонах катушек, а выводы начал катушек одноименных фаз звезды и треугольника расположены в общем пазу (смещение равно 0 эл. град.).4. Обмотка по п.1, отличающаяся тем, что выводы катушек выполнены на внутренних сторонах катушек, при этом выводы начал катушек одноименных фаз звезды и треугольника расположены в общем пазу (смещение равно 0 эл. град.).1. The winding of a bipolar three-phase electric machine with the number of grooves z = 18, with a step y = 1-10, with the number of parallel branches a = 1 and the ratio of the number of turns of the even coils connected into a triangle to the number of turns of the odd coils connected into a star, is equal to consists of six one-two-layer two-section chain coils with a ratio of the number of turns in single-layer sections to the number of turns of two-layer sections equal to 2: 1, the terminals are located on the outer sides of the coils, characterized in that the even and odd coils are laid out in a fork, and the beginning of ears of similar phases stars and triangles are offset by two slots (40 el. deg.). 2. The winding according to claim 1, characterized in that the conclusions of even coils are made on the inner sides of the coils. The winding according to claim 1, characterized in that the conclusions of the odd coils are made on the inner sides of the coils, and the conclusions of the beginnings of the coils of the same phases of the star and the triangle are located in a common groove (offset is 0 electric degrees). The winding according to claim 1, characterized in that the leads of the coils are made on the inner sides of the coils, while the leads of the coils of the same phases of the star and the triangle are located in a common groove (offset is 0 el. Degrees).
