Description

В результате такого равномерного распределени  жгутов магнитна  структура клица, образованна  ферромагнитным порошком и полимерным св зующим, также получаетс  равномерной. Равномерное распределение жгутов из стекловолокна, расположенных вдоль продольной оси клина, уменьшает возможность расслаивани  и растрескивани  клиньев при запрессовке и .термоударах, неизбежных при работе электрической машины.As a result of such an even distribution of the harnesses, the magnetic structure of the klice formed by the ferromagnetic powder and the polymeric binder is also obtained uniformly. The uniform distribution of fiberglass harnesses located along the longitudinal axis of the wedge reduces the possibility of delamination and cracking of wedges during pressing and thermal shock, inevitable when the electric machine is in operation.

Применение жгутов из стекловолокна создает лучшие услови  дл  пропитки, поскольку происходит обволакивание отдельных волокон и проникновение частиц ферромагнитного порошка между волокнами в жгуты. Получаетс  более равномерное распределение порошка по всему поперечному сечению клина, что улучшает диэлектрические и магнитные свойства клина. The use of fiberglass tows creates the best conditions for impregnation, since the individual fibers are enveloped and ferromagnetic powder particles penetrate between the fibers into the tows. A more uniform distribution of the powder over the entire cross section of the wedge is obtained, which improves the dielectric and magnetic properties of the wedge.

Магнитный клин получают следующим образом.Magnetic wedge is obtained as follows.

Жгуты из стекловолокна пропускают через ванну с полимерным св зующим, в которое введен ферромагнитный порошок. Дл  обеспечени  лучших условий пропитки ванна обогреваетс , а св зующее посто нно перемешиваетс . Пропитанные такимFiberglass tows are passed through a polymer binder bath in which a ferromagnetic powder has been introduced. To ensure the best impregnation conditions, the bath is heated and the binder is constantly stirred. Soaked in such

образом жгуты поступают затем в подогреваемую фильеру, форма сечени  которой соответствует форме сечени  клина. При прот гивании пропитанных жгутов через фильеру происходит непрерывное формование профил  клина. Непрерывна  прот жка обеспечивает простоту и технологичность изготовлени  клина.The strands then enter a heated die, the shape of which corresponds to the shape of the wedge. When the impregnated harnesses are pulled through a die, the wedge profile is continuously molded. Continuous stretching ensures the simplicity and manufacturability of the wedge.

Описанна  конструкци  клина позвол ет повысить его механическую прочность.The wedge design described above makes it possible to increase its mechanical strength.
