Abstract
(DE) Die Erfindung betrifft einen Nutverschluss (1,1´) zum Verschließen einer Nut (12) eines Aktivteils (2,3) einer elektrischen Maschine (10), wobei der Nutverschluss (1,1´) einen Kanal (6) zur Führung eines Fluids (20) aufweist. Ferner ist ein Verfahren zur Kühlung einer elektrischen Maschine (10) angegeben, wobei die elektrische Maschine (10) Nuten (12) aufweist, wobei die Nuten (12) mit Nutverschlüssen (1,1´) verschlossen sind, wobei zumindest ein Nutverschluss (1,1) einen Kanal (6) aufweist und wobei durch den Kanal (6) ein Fluid (20) zur Kühlung der elektrischen Maschine (10) geführt wird. Entsprechend ist diesbezüglich dann auch ein Computerprogrammprodukt vorgesehen.
(EN) The invention relates to a slot seal (1, 1´) for sealing a slot (12) of an active part (2, 3) of an electric machine (10), the slot seal (1,1´) having a duct (6) for guiding a fluid (20). The invention also relates to a method for cooling an electric machine (10), wherein the electric machine (10) has slots (12), the slots (12) are sealed by means of slot seals (1, 1´), at least one slot seal (1, 1) has a duct (6), and a fluid (20) is guided through the duct (6) for cooling the electric machine (10). A computer program product is also accordingly provided in this respect.
(FR) L'invention concerne une fermeture (1, 1') d'encoche pour fermer une encoche (12) d'une partie active (2, 3) d'une machine électrique (10), la fermeture (1, 1') d'encoche ayant un conduit (6) pour guider un fluide (20). L'invention concerne également un procédé de refroidissement d'une machine électrique (10), la machine électrique (10) présentant des encoches (12), les encoches (12) étant fermées au moyen de fermetures (1, 1') d'encoche, au moins une fermeture (1, 1') d'encoche présentant un conduit (6), et un fluide (20) étant guidé à travers le conduit (6) pour refroidir la machine électrique (10). Un produit programme d'ordinateur est également prévu à cet égard.
