Combined winding "Slavyanka"

Revolution in the field of electric motors

About the combined winding technology "Slavyanka"

The combined winding technology "Slavyanka" is applicable for most types and kinds of electrical rotating machines, both single-phase and three-phase ones. In their classic version, these motors are designed with either a "star" or "delta" winding.

The peculiarity of "Slavyanka" is combining two winding types in one electric motor. "Star" and "Delta" are combined in parallel with a 30-electrical-degree shift of the resultant electromagnetic induction vectors.

The combined winding was named "Slavyanka". Motors with this winding type have unique performance features and outperform all the world rivals available in the market.

    Comparative tests of the "Slavyanka"-rewound motor. University of Bologna, September 2013

    Задача испытания — создать мотор с совмещёнными обмотками для электробагги на базе технологии «Славянка» и провести его сравнительное испытание со стандартным двигателем.

    Стандартный мотор, изготовленный специально для багги, весил 54 кг и имел медный ротор. Для тестирования технологии «Славянка» был выбран общепромышленный двигатель весом 27 кг с алюминиевым ротором.

    Его технические характеристики: 4-х полюсный мотор AEG 100-го габарита, 3 кВт, с КПД 86% и классом энергоэффективности IE2. При испытаниях использовался контроллер, разработанный в университете, который прекрасно синхронизировался с двигателем, перемотанным по технологии Дуюнова.

    Тестирование проводилось в трех различных режимах: • номинальном 135 А , • 270 А , • 350 А .

    В итоге модифицированный двигатель не добрал 1 кВт по номиналу и 1 кВт по максимальной мощности. Прежний мотор от электробагги выдавал 20 кВт мощности на 350 Амперах, а с совмещёнными обмотками – 19 кВт.

    There were differences in the efficiency values too: the electric buggy motor - 91%, the modified general-purpose industrial motor with "Slavyanka" – 89%.

    Виктор Арестов, руководивший испытаниями, признал, что выбор двигателя для тестирования был не совсем верным. Для достижения запланированных результатов следовало выбрать мотор не 100-го, а 112 габарита, с большей мощностью в 4 кВт.

    Однако, стоит учесть тот факт, что разница в весе моторов была почти двукратной, а специальный двигатель для электробагги имел медный ротор, тогда как модифицированный мотор — алюминиевый (изменив алюминиевый ротор на медный, можно увеличить КПД на 2-3%).

    При этом, мотор с совмещёнными обмотками весом 27 кг показал практически такие же параметры, как специально разработанный оригинальный двигатель весом 54кг!

    В Белгородском государственном технологическом университете были проведены сравнительные испытания двух асинхронных электродвигателей АИР 71В4.

    Целью мероприятия была проверка заявленных характеристик электромотора АИР 71В4, модернизированного по технологии «Славянка», с аналогом заводского исполнения, но со стандартной трехфазной обмоткой.

    В процессе испытаний отмечено снижение шума и температуры нагрева модифицированного мотора. Зафиксировано значительное улучшение характеристик модернизированного электродвигателя практически во всех режимах и увеличение КПД в более широком диапазоне нагрузок.

    Был сделан вывод, что в процессе реальной эксплуатации двигатель с совмещенными обмотками позволит снизить потребление электроэнергии на 14-20%. Наиболее высокие показатели экономии могут быть достигнуты в режимах работы электропривода с нагрузкой на двигатель ниже номинальной. Кроме того, снижение величин пусковых и номинальных токов, уменьшение рабочей температуры обмотки статора, уменьшение внутренней вибрации проводников в катушках и пазах статора значительно снизят темпы износа изоляции проводников.

    Исследователи рекомендовали технологию «Славянка» для ремонта асинхронных электродвигателей на промышленных предприятиях с целью значительной экономии электроэнергии.

    Testing the motor with "Slavyanka". Belgrade, October 7, 2015

    Цель тестирования — определить, как изменились характеристики электродвигателя после смены типа обмотки с традиционного на сочетание «звезда-треугольник».

    В сербскую компанию D.O.O. «Savian» поступил на модернизацию асинхронный электромотор мощностью 15 кВт со сгоревшей обмоткой. Двигатель эксплуатировался в условиях каменоломни. Владелец мотора, компания D.O.O. Kuevo, заказала его полноценный ремонт со сменой типа обмотки.

    В результате применения энергосберегающей технологии «Славянка» технические характеристики модернизированного двигателя изменились следующим образом.

    The nominal power increased from 15 kW to 19 kW, i.e., by 26.6%.

    Токи холостого хода до ремонта не определялись, так как двигатель был неисправен. По паспорту данное значение составляло 27 А, а после модернизации снизилось до 13,4 А.

    Проведенные испытания наглядно продемонстрировали энергоэффективность технологии «Славянка». Технический директор D.O.O. Kuevo подтвердил надежность работы модернизированного двигателя.

    Инженеры российского завода своими силами провели модернизацию асинхронного электродвигателя 5АИ160М2У2 мощностью 18,5 кВт, установленного в дренажном насосе. Во время ремонта сгоревшая старая обмотка была удалена путем обжига, а двигатель перемотали с применением запатентованной технологии «Славянка».

    The goal of the tests is to identify changes in the motor performance characteristics after modernization.

    До ремонта электродвигатель 5АИ160М2 был рассчитан на работу с напряжением 660В, после модернизации питается от 380В. При напряжении 500В, поданном в лабораторных условиях, холостой ток уменьшился в среднем на 12% (с 27,3 А до 24,0 А). При работе от 380В холостой ток уменьшился на 3%, а при работе под нагрузкой — на 2%.

    После перемотки увеличилась производительность насоса (длительность цикла работы насоса снизилась на 39 секунд). Это привело к уменьшению необходимого времени работы двигателя на 8%. Общая экономия энергии за одно включение насоса составила 12 %. Потребляемая энергия при откачке бака до перемотки достигала 2,573 кВт, после перемотки снизилась 2,3368 кВт. Экономия — 10%.

    The test results confirmed the efficiency of the combined winding technology "Slavyanka".

    In 2014, the citizen of Belgorod region Igor Korkhov modernized the general purpose industrial motor in size 100 by rewinding it using the "Slavyanka" technology. As a result, the motor became 10 times more powerful with a comparatively light weight of 29 kilograms.

    Before modernization, the motor power was 4 kW, and after - increased up to 12-13 kW, with the maximum of 50 kW.

    "Igor Korkhov equipped the Tavria car with a modernized motor. The heavy car started quite vigorously in both first and third gear, while running very quietly. The maximum speed of the car amounted to 110 km/h, and it could run about 100 kilometres on a single charge ."

    Igor Korkhov started modernizing Tavria back in the beginning of 2000s. The car had already been equipped with an electric motor, but the engineer wasn't satisfied with the speed that didn't exceed 50 km/h. So, he first equipped Tavria with an American commutator electric motor, and then - with a combined winding motor completed with a Curtis controller.

    Tavria has been in running order to the present day and is used by its new owner. And Igor Korkhov is a member of Duyunov's team now working for "SovElMash" in Zelenograd.
