Abstract
Изобретение относитс к электромашиностроению. Цель изобретени - повышение КПД путем снижени вентил ционных потерь. Ротор 1 имеет остов 2, представл ющий собой центральную часть 3, стыковые плиты 4 с закрепленными на них спицами 5. В спицах 5 имеютс заборные окна 6 дл подачи охлаждающего воздуха в раздаточные каналы 7, которые образуютс наклонно-направл ющими щитами 8 и боковыми стенками. В межспицевом пространстве 10 наклонно-направл ющие щиты 11 и внешние стороны спиц 5 образуют раздаточные каналы 12. Щиты 8 и 11 наклонены в противоположные стороны. При вращении ротора охлаждающий воздух через окна 6 и 5 по каналам 7 и 12 поступает в вентил ционные каналы 16 обода 17 и далее к полюсам 18. 2 ил.The invention relates to electrical engineering. The purpose of the invention is to increase the efficiency by reducing ventilation losses. The rotor 1 has a core 2, which is a central part 3, butt plates 4 with needles 5 fixed on them. In the spokes 5 there are intake ports 6 for supplying cooling air to the dispensing channels 7, which are formed by inclined guiding shields 8 and side walls . In the inter-spoke space 10, the inclined-guiding shields 11 and the outer sides of the spokes 5 form the dispensing channels 12. The shields 8 and 11 are inclined in opposite directions. When the rotor rotates, the cooling air through the windows 6 and 5 through the channels 7 and 12 enters the ventilation channels 16 of the rim 17 and further to the poles 18. 2 Il.
