Изобретение относитс  к области электротехники.This invention relates to the field of electrical engineering.

Известен статор электрической машины , имеющий канал между обмоткой и стенкой паза. Однако в указанной ,конструкции крепление обмотки в пазах статора при помощи распорных элементов недостаточно надежно, так как при работе машины стержни обмотки под действием динамических сил могут перемещатьс  в тангенциальном направлении, что приво,цит к повреждению изол ции и снижению эксплуатационной надежности машины. Кроме того, крепление обмотки в пазах статора при помощи распорных и опорных изол ционных элементов усложн ет конструкцию и технологию выполнени  статора, а также увеличивает аэродинамическое сопротивление каналов вентил ционного тракта магнитопровода статора,так как распорные и опорные элементы занимают часть сечени  каналов дл  прохода хладагента.Known stator of an electric machine, having a channel between the winding and the wall of the groove. However, in this design, the fastening of the winding in the stator slots using spacer elements is not sufficiently reliable, since during operation of the machine, the winding rods under the action of dynamic forces can move in the tangential direction, which can damage the insulation and reduce the operational reliability of the machine. In addition, fastening the winding in the stator slots using spacer and support insulating elements complicates the design and technology of the stator, and also increases the aerodynamic resistance of the channels of the ventilation path of the stator magnetic circuit, since the spacer and support elements occupy part of the cross section of the refrigerant passage channels.

Наиболее близким к изобретению по технической сущности  вл етс  статор электрической машины, содержащий обмотку и сердечник с пазгми.Closest to the invention in its technical essence is the stator of an electric machine, comprising a winding and a core with pgsgms.

в которых размещена обмотка, имеющий группы чередующихс  пакетов, одни из которых выполнены с подпазовыми каналами , а другие - с каналами, расположенными между обмоткой и стенками пазов.in which is placed a winding having groups of alternating packages, some of which are made with podpazovy channels, and others - with channels located between the winding and the walls of the grooves.

Целью изобретени   вл етс  повышение эксплуатационной надежности машины путем улучшени  охлаждени  статора. Это достигаетс  тем, что в предлагаемом статоре кажда  группа пакетов снабжена по меньшей мере одним дополнительным пакетом с каналами , расположенными между обмоткой и стенкой паза, и пакеты с подпазовыми каналами выполнены с дополнительными надпазовыми каналами, причем в каждой группе пакеты с каналами, расположенными между обмоткой и стенками пазов, выполнены с различным поперечным сечением и размещены между пакетами и надпазовыми и подпазовыми каналами.The aim of the invention is to increase the operational reliability of the machine by improving the cooling of the stator. This is achieved in that, in the proposed stator, each group of packages is provided with at least one additional package with channels located between the winding and the groove wall, and packages with sub-channel channels are made with additional channel channels, and in each group the packages with channels located between the winding and the walls of the grooves are made with a different cross-section and are placed between the packages and the supra-and sub-grooves.
