Description
Изобретение относитс к области электромашиностроени , в частности к полюсопереключаемым обмоткам электродвигателей nepsMetiHoro тока.The invention relates to the field of electrical engineering, in particular to the pole-switched windings of nepsMetiHoro electric motors.
Известны трехфазные двухслойные полюсопереключаемые обмотки с отношением чисел полюсов 6/4, с числом катушек кратным 27, с шестью вывод,ами , выполненные с сопр жением. фаз,. 1 .Three-phase two-layer pole-switching windings are known with a pole ratio of 6/4, with a number of coils of a multiple of 27, with a six pin, am, made with coupling. phases, one .
Однако такие оьмоГки либо нетехнологнчны в изготовлении и неудобны при укладке в статор, так как они выполн ютс из разновитковых катушек либо их применение приводит к недостаточно высокому использованию активной части двигател .However, such dangers are either non-technological to manufacture and inconvenient when placed in the stator, since they are made of different-turn coils or their use leads to an insufficiently high use of the active part of the engine.
Из известных обмоток наиболее близкой по технической сущности к предлагаемой вл етс трехфазна двухслойна полюсопереключаема обмотка с отношением чисел полюсов 6/4 с числом катушек кратным 27, с сопр жением фаз AVs/AAt. и шестью выводами с подключением напр жени при к выводам 6С1, 6С2, 6СЗ, а при к 401, 4С2, 4СЗ 2 .Of the known windings, the closest in technical essence to the proposed one is a three-phase two-layer pole-selectable winding with a pole ratio of 6/4 and a number of coils of a multiple of 27, with junction of AVs / AAt phases. and six pins with connecting voltage at pins 6С1, 6С2, 6СЗ, and at k 401, 4С2, 4СЗ 2.
Она выполнена таким образом, что при работе двигател на одной из двух скоростей вращени часть обмотки неIt is designed in such a way that when the engine is running at one of the two rotational speeds, part of the winding does not

Целью изобретени вл етс повы 11ение энергетических показателей и мощности двигател .The aim of the invention is to increase the energy performance and engine power.
Это достигаетс соответствующим распределением катушек обмотки по катушечным группам и катушечных групп по параллельныч1 вэтв м, причем на обС их скорост х вращени обметка, состо ща из одинаковых катушек, используетс полностью. Коэффициенты распределени .л обмотки близки к максимальнмм, This is achieved by appropriately distributing the winding coils among the coil groups and the coil groups along parallel lines, and at their speeds of rotation, overlay consisting of identical coils is fully utilized. The distribution coefficients of the winding are close to maximum,

Обмотка выполнена с сопр жением фаз ,Ж/Ш и имеет б выводов.5 and the magnitudes of magnetic inductions in the air gap, differing at both speeds, are approximately 15%. The winding is made with the mapping of phases, F / W and has b conclusions.
