Description
йых обмоток с отношением чисел пар полюсов 1 :2, в котором при переходе с одного числа полюсов на другое измен етс напра:вление то,ка в половине обмотки.windings with the ratio of the numbers of pole pairs 1: 2, in which, when switching from one number of poles to another, the direction changes in half of the winding.
Трехскоростна обмотка имеет И выводов. При 2/ 8 питание подаетс на клеммы As, Be и GS. При этом должны быть соединены клеммы А4 с А4/Вб, 64 с и €4 с С /ВвРабота двигател при осущестал етс подачей питани на клеммы А4, 84 и С при закороченных клеммах AS, Bs и Cs.The three speed winding has AND conclusions. At 2/8, power is applied to terminals As, Be and GS. In this case, terminals A4 should be connected to A4 / Vb, 64 s, and € 4 to C / V. The engine is supplied with power to terminals A4, 84 and C with shorted terminals AS, Bs and Cs.
При трехфазное питание подаетс на клеммы Аб и Сб и соединенные вместе клеммы А4/Ве -В4/Вб-С4/Вб, образующие вход фазы Вб. Некотора несимметри обмотки, имеюща место при Т-образном включении, не оказывает существенного вли ни на характеристики двигател .When three-phase power is supplied to the terminals Ab and Sb and the A4 / Be-B4 / Wb-C4 / Wb terminals connected together, which form the input of the Wb phase. Some asymmetry of the winding, which occurs when the T-shaped inclusion, does not have a significant impact on the characteristics of the engine.
Предлагаема трехскоростна обмотка отличаетс простотой, небольшим числом выводов , минимальным числом катушечных групп и междукатушечных соединений.The proposed three-speed winding is characterized by simplicity, a small number of leads, a minimum number of coil groups and paddle connections.
Предмет изобретени Subject invention
Трехфазна трехскоростна полюсопереключаема обмотка машин переменного тока с отношением чисел пар полюсов 2:3:4, содержаш ,а 12 одинаковых катушечных групп, равномерно распределенных по расточке статора отличающа с тем, что, с целью упрощени обмотки и уменьшени числа выводов , перва и втора фазы содержат по три параллельные катушечные группы с пор дковыми номерами дл первой фазы 1, 5, 9, дл второй фазы 3, 7, 11, а треть фаза содержит шесть катушечных групп, соединенных в три параллельные ветви с последовательным включением двух катушечных групп в каждой ветви с номерами 4 и 10, 12 и 6, 8 , причем средние точки параллельных ветвей третьей фазы образуют выводы обмотки с числом полюсов р 4, а точки соединени параллельных ветвей трех фаз и концы трех параллельных ветвей третьей фазы образуют выводы обмотки дл р 2.The three-phase, three-speed pole-switching winding of alternating current machines with the ratio of the numbers of pole pairs 2: 3: 4 contains and 12 identical coil groups uniformly distributed over the stator bore, which in order to simplify the winding and reduce the number of outputs, the first and second phases contain three parallel coil groups with sequence numbers for the first phase 1, 5, 9, for the second phase 3, 7, 11, and the third phase contains six coil groups connected in three parallel branches with the series connection of two coils groups in each branch with numbers 4 and 10, 12 and 6, 8, the middle points of parallel branches of the third phase form winding pins with the number of poles p 4, and the connection points of parallel branches of three phases and the ends of three parallel branches of the third phase form winding pins for p 2.
