Abstract:
(EN) The invention relates to: a stator (14) for an electrical machine (2), in particular for an electromotive drive machine for an electric or hybrid vehicle, having a stator core stack (16) with a stator yoke (18) and a number of radial stator teeth (20), as well as a corresponding number of stator slots (22), arranged between the stator teeth (20), for receiving a stator winding (24); and a cooling device (26) comprising a number of cooling channels (30), each of which runs axially in one of the stator slots (22).
(FR) L’invention concerne un stator (14) destiné à un moteur électrique (2), en particulier destiné à un moteur électrique d’entraînement d’un véhicule électrique ou hybride, présentant un noyau feuilleté de stator (16), une culasse de stator (18) et un certain nombre de dents de stator (20) orientées radialement, ainsi qu’un nombre correspondant d’encoches de stator (22) agencées entre les dents de stator (20), logeant un enroulement de stator (24), et un dispositif de refroidissement (26) muni d’un certain nombre de canaux de refroidissement (30) qui sont chacun agencés axialement dans une des encoches de stator (22).
(DE) Stator (14) für eine elektrischen Maschine (2), insbesondere für eine elektromotorischen Antriebsmaschine für ein Elektro- oder Hybridfahrzeug, aufweisend ein Statorblechpaket (16) mit einem Statorjoch (18) und mit einer Anzahl von radial gerichteten Statorzähnen (20) sowie mit einer entsprechenden Anzahl von zwischen den Statorzähnen (20) angeordneten Statornuten (22) zur Aufnahme einer Statorwicklung (24), und eine Kühlvorrichtung (26) mit einer Anzahl von Kühlkanälen (30), die jeweils in einer der Statornuten (22) axial verlaufend angeordnet sind.
