Abstract

1. Статор электрической машины, содержащий корпус, сердечник с вентиляционными каналами, обмотку, лобовые части которой имеют форму корзины, внешнее и внутреннее кольца для крепления лобовых частей обмотки, узел крепления внешнего кольца к корпусу, отличающийся тем, что во внутреннем кольце выполнены вентиляционные отверстия, а между корзиной и наружным кольцом - полости, сообщающиеся через проходы в корзине с вентиляционными отверстиями во внутреннем кольце, причем указанные полости расположены напротив выхода из вентиляционных каналов сердечника.2. Статор по п.1, отличающийся тем, что во внешнем кольце выполнены вентиляционные отверстия, с которыми сообщаются полости.3. Узел крепления внешнего кольца к корпусу статора электрической машины, содержащий упругие элементы, каждый из которых закреплен одним концом на корпусе, а другим - на внешнем кольце, отличающийся тем, что упругий элемент выполнен в виде шпильки.4. Узел крепления по п.3, отличающийся тем, что шпилька выполнена с резьбовыми концами, на одном из которых размещена закрепленная на корпусе гайка.1. The stator of an electric machine, comprising a housing, a core with ventilation channels, a winding whose frontal parts are in the form of a basket, an outer and inner ring for attaching the frontal parts of the winding, an attachment unit of the outer ring to the housing, characterized in that the ventilation rings are made in the inner ring and between the basket and the outer ring - the cavity communicating through the passages in the basket with ventilation holes in the inner ring, and these cavities are located opposite the exit of the ventilation ducts in the core. 2. The stator according to claim 1, characterized in that in the outer ring there are ventilation openings with which the cavities communicate. The attachment site of the outer ring to the stator housing of the electric machine, containing elastic elements, each of which is fixed at one end to the housing, and the other on the outer ring, characterized in that the elastic element is made in the form of a stud. 4. The fastening assembly according to claim 3, characterized in that the stud is made with threaded ends, one of which has a nut fixed to the housing.
