Description
Изобретение относитс к конструкци м электрических машин средней и большой мощности.The invention relates to the design of electric machines of medium and high power.
Известна электрическа машина, име юща щеточноколлекторный узел, рас- положенный под лобовой частью обмотки 1 .A known electric machine having a brush collector unit located under the frontal part of the winding 1.
Однако така конструкци характеризуетс недостаточной эксплуатационной надежностью электрической машины из-за загр знени рабочей поверхности коллектора продуктами износа деталей токосъема.However, such a structure is characterized by insufficient operational reliability of the electric machine due to the contamination of the working surface of the collector with wear products of the current collection parts.
Наиболее близкой к предлагаемой вл етс электрическа машина с двум коллекторами, расположенными по обе стороны от сердечника ротора и лобовых частей обмотки 2.Closest to the present invention is an electric machine with two manifolds located on either side of the rotor core and the frontal parts of the winding 2.
Недостаток известной конструкции заключаетс в значительной аксиальной длине машины.A disadvantage of the known construction lies in the considerable axial length of the machine.
Цель изобретени - повышение эксплуатационной надежности.The purpose of the invention is to increase operational reliability.
Поставленна цель достигаетс тем, что щеточноколлекторные узлы расположены внутри лобовых частей обмотки, а сердечник имеет аксиальный канал, выходы которого обращены к поверхност м сопр жени щеток с коллекторами, а вход через радиальные каналы сооб2The goal is achieved by the fact that the brush-collector units are located inside the frontal parts of the winding, and the core has an axial channel, the outlets of which are facing the interfaces of the brushes with the collectors, and the entrance through the radial channels is communicating
щен с каналом подвода хладагента., расположенным в валу.Schen with a channel for supplying a refrigerant. Located in the shaft.
На чертеже показана предлагаема г электрическа машина.The drawing shows the proposed electric machine.
Электрическа машина включает статор 1, в котором вращаетс на полом валу 2 ротор 3, который имеет два д коллектора 4 с поверхностью 5 сопр гжени щеток с коллекторами, расположенные под лобовыми част ми 6 обмоток.The electric machine includes a stator 1, in which a rotor 3 rotates on a hollow shaft 2, which has two collectors 4 with a surface 5 of matching brushes with collectors located under the frontal parts 6 of the windings.
Сердечник ротора 7 имеет систему . радиальных 8 и аксиальных 9 каналов. 15 Выходы 10 каналов 9 обращены к поверхност м 5 сопр жени щеток с коллекторами .The core of the rotor 7 has a system. radial 8 and axial 9 channels. 15 The outlets 10 of the channels 9 face the interfaces of 5 brushes to the collectors.
Хладагент подаетс через полый Coolant is fed through the hollow
