Abstract

Det er beskrevet en vertikalakslet elektrisk vann- kraftmaskin med en med et nav (3) forsynt rotor- stjerne, på hvis ytre omfang det er anordnet en rotorkrans (7). Denne bærer rotorpoler (14) av polplater lagt i lag, og polviklinger (15). Sta- torplatelegemet (18) består likeledes av plater lagt i lag, og er forsynt med spor på sitt indre omfang for å holde en statorvikling (28) som på begge frontsider av platelegemet er forsynt med statorviklingshoder (41, 42) og viklingsforbindel- ser. Såvel rotorkrans (7) som statorplatelegemet (18) har radialt forløpende kjøleslisser (9, 19) gjennom hvilke kjøleluft kan føres fra navet gjen- nom nevnte slisser (9) i rotorkransen, gjennom j åpninger (16) mellom polene, gjennom luftspalten j (17) og slissene (19) i statorplatelegemet (18) og i inn i et ringrom som omgir dette med kjølere (23), ; og derfra igjen ut mot navet. Rotoren virker her- ; ved som transport- og trykkgenereringsmiddel for i kjøleluften. j For inndeling i skott av maskinluftspalten (17) i overfor viklehoderommet (39, 40), er det på rotor- i polene (14) på begge frontsider festet tetningspla- ¿ ter (24) som strekker seg inn i maskinluftspalten j (17) frem til nærheten av statorboringen og som er i anordnet tett i tett sett i omfangsretning ved ; dannelse av små spalter (34) . Disse danner på denne måte en ringtetning. Således ligger vik- lingshodet (41, 42) og viklingsforbindelsene i ! friskluft-strømmen bak kjølerne (23) og blir kjølt optimalt.
