Abstract: Сущность изобретения: мотор-колесо содержит закрепленный на полой оси якорь 2 с магнитопроводом 3, на котором размещены две группы электромагнитов 4.1 и 4.2. Индуктор 5 подвижно закреплен на оси 1 и имеет магнитопровод 6 с постоянными магнитами 7, размещенными равномерно с чередующимися полярностями. На роторе 5 размещен распределительный коллектор, представляющий собой равномерно размещенные по окружности на изоляционном основании токопроводящие изолированные пластины 9, 10, 11. Пластины 9 и 10 сгруппированы через одну в группы и соответственно соединены между собой . Кольцевой контакт электрически соединен с одной группой пластин 9, другая группа 10 через корпус соединена с первым выводом источника регулируемого напряжения. Распределительный коллектор может располагаться как на роторе, так и на статоре. В результате реализуется обращенная конструкция с постоянными магнитами на роторе, что позволяет за счет размещения постоянных магнитов на роторе упростить конструкцию, повысить мощность и скорость за счет подвода большего тока и улучшить тепловой режим. 14 з.п. ф-лы, 3 ил.
