Abstract

Для повышения механической жесткости и собственной частоты колебаний статора во вращающейся электрической машине, в статоре которой имеются зубцы (10) между пазами (8), куда помещается обмотка, и свободные концы указанных зубцов расположены в воздушном зазоре (7) между статором и ротором, в каждом промежутке между свободными концами соседних зубцов (10) статора установлена повышающая жесткость распорка (11). Таким образом, эти концы зафиксированы в тангенциальном направлении.Международная заявка была опубликована вместе с отчетом о международном поиске.To increase the mechanical rigidity and natural frequency of the stator oscillations in a rotating electric machine, in the stator of which there are teeth (10) between the slots (8) where the winding is placed, and the free ends of these teeth are located in the air gap (7) between the stator and the rotor, each gap between the free ends of adjacent teeth (10) of the stator is installed stiffening strut (11). Thus, these ends are fixed in a tangential direction. The international application was published along with an international search report.
