Abstract[German]
Stator einer elektrischen Maschine (2) mit einem Statorblechpaket (3), an dem Statorzähne (5) und zwischen den Statorzähnen (5) liegende Statornuten (6) ausgebildet sind und das ein Paket von Blechlamellen (7) umfasst, und mit einer durch die Statornuten (6) verlaufenden Statorwicklung (8), wobei sich die Statornuten (6) in radialer Richtung bezüglich einer Statorachse (4) jeweils zwischen einem Nutgrund (6g) und einem Nutschlitz (6s) erstrecken, wobei die Statornuten (6) von einem Kühlfluid durchströmbar sind und wobei die Nutschlitze (6s) von einer Statorhülse (10) verschlossen sind, wobei die Statorhülse (10) an ihrem den Statorzähnen (5) zugewandten Umfang Versteifungsrippen (11) aufweist, dadurch gekennzeichnet, dass zumindest eine der Versteifungsrippen (11) in Umfangsrichtung verläuft unter Bildung jeweils einer Umfangsrippe (11U) und in Zahnschlitzen (12) der Statorzähne (5) aufgenommen ist.[English]
The invention relates to a stator of an electric machine (2) having a stator laminated core (3) on which are formed stator teeth (5) and stator grooves (6) lying between the stator teeth (5), said stator laminated core comprising a stack of laminations (7), and having a stator winding (8) which extends through the stator grooves (6), wherein the stator grooves (6) extend in the radial direction in relation to a stator axis (4) between a groove base (6g) and a groove slot (6s) in each case, wherein a cooling fluid can flow through the stator grooves (6) and wherein the groove slots (6s) are closed by a stator sleeve (10), wherein the stator sleeve (10) has reinforcing ribs (11) on its circumference facing the stator teeth (5), characterised in that at least one of the reinforcing ribs (11) extends in the circumferential direction, thereby forming in each case a circumferential rib (11U) and is received in tooth slots (12) of the stator teeth (5).[French]
L'invention concerne un stator d'une machine électrique (2) ayant un noyau feuilleté (3) de stator sur lequel sont formées des dents (5) de stator et des rainures (6) de stator situées entre les dents (5) de stator, ledit noyau feuilleté de stator comprenant un empilement de tôles (7), et ayant un enroulement statorique (8) qui s'étend à travers les rainures (6) de stator, les rainures (6) de stator s'étendant dans la direction radiale par rapport à un axe (4) de stator entre une base (6g) de rainure et une fente (6s) de rainure dans chaque cas, un fluide de refroidissement pouvant s'écouler à travers les rainures (6) de stator et les fentes (6s) de rainure étant fermées par un manchon (10) de stator, le manchon (10) de stator ayant des nervures de renfort (11) sur sa circonférence faisant face aux dents (5) de stator, caractérisées en ce qu'au moins l'une des nervures de renfort (11) s'étend dans la direction circonférentielle, formant ainsi dans chaque cas une nervure circonférentielle (11U) et est reçue dans des fentes (12) de dent des dents (5) de stator.
