Abstract: Изобретение относится к электротехнике, а именно к электрическим машинам, и может быть использовано в устройствах, работающих в кратковременном или повторно-кратковременном режиме, а также в устройствах, рабочий цикл которых включает как продолжительный, так и кратковременный режим работы. В способе и электродвигателе многократное изменение номинальной мощности частотно-регулируемого электродвигателя осуществляют путем варьирования числа витков фазы электродвигателя. Номинальную частоту напряжения изменяют таким образом, чтобы произведение числа витков фазы на номинальную частоту напряжения оставалось неизменным. Для обеспечения варьирования числа витков фазы якорная обмотка электродвигателя выполнена разделенной на части с одинаковым числом витков с возможностью их соединения или последовательно, или параллельно, или последовательно-параллельно в зависимости от режима работы. В результате на порядок увеличивается допустимая мощность электродвигателя при работе его в кратковременном режиме. Возможен выбор базового электродвигателя значительно меньшего типоразмера по сравнению с существующими рекомендациями, снижается трудоемкость и стоимость изготовления с использованием узлов базового электродвигателя. Изобретения могут быть реализованы, когда требуется кратковременное увеличении мощности или для обеспечения большого динамического момента, в частности для приведения в движение больших инерционных масс, или в конце их движения для защелкивания какого-либо ограничителя, или в электростартерах с ограниченными размерами и массой. 2 н. и 3 з.п. ф-лы, 1 ил.
