(DE) ELEKTRISCHE MASCHINE UND ZUGEHÖRIGES HERSTELLUNGSVERFAHREN
Abstract:
(EN) The invention relates to an electric machine (1), in particular for a motor vehicle, comprising a stator (3) having a laminated core (4), from which winding heads (5) of an electrical winding (7) protrude at at least one axial end (6), wherein, at the at least one axial end (6), an annular holding region (13) is provided by a housing (12) and/or an associated end shield (11), in which holding region the winding heads (5) are arranged. Cooling of the winding heads should be provided. According to the invention, at least one electrically insulating, permanently elastic material (15) is arranged between the winding heads (5) and an inner wall (14) of the holding region (13), which material touches the winding heads (5) and the inner wall (14) and thermally couples the winding heads and the inner wall and has a thermal conductivity of greater than 1 W/mK for this purpose.
(FR) L'invention concerne une machine électrique (1), en particulier pour un véhicule à moteur, qui présente un stator (3) doté d'un paquet de tôles (4) d'où font saillie à au moins une extrémité axiale (6) dans chaque cas des têtes de bobine (5) d'un enroulement (7) électrique, une zone de réception (13) annulaire étant ménagée à ladite au moins une extrémité axiale (6), dans chaque cas par un boîtier (12) et/ou un flasque (11), zone de réception dans laquelle les têtes de bobine sont disposées. L'invention vise à fournir un refroidissement de tête de bobine. Selon l'invention, au moins un matériau électriquement isolant à élasticité continue (15) est disposé entre les têtes d'enroulement (5) et la paroi intérieure (14) de la zone de réception (13), ledit matériau touchant les têtes d'enroulement (5) et une paroi intérieure (14) et les couplant thermiquement et disposant à cet égard d'un coefficient de conductivité thermique supérieur à 1 W/mK.
(DE) Die Erfindung betrifft eine elektrische Maschine (1), insbesondere für ein Kraftfahrzeug, aufweisend einen Stator (3) mit einem Blechpaket (4), aus welchem an zumindest einem axialen Ende (6) jeweils Wickelköpfe (5) einer elektrischen Wicklung (7) herausragen, wobei an dem zumindest einen axialen Ende (6) jeweils durch ein Gehäuse (12) und/oder einen jeweiligen Lagerschild (11) ein ringförmiger Aufnahmebereich (13) bereitgestellt ist, in welchem die Wickelköpfe (5) angeordnet sind. Es soll eine Wickelkopfkühlung bereitgestellt werden. Die Erfindung sieht vor, dass zwischen den Wickelköpfen (5) und einer Innenwandung (14) des Aufnahmebereichs (13) zumindest ein elektrisch isolierendes, dauerelastisches Material (15) angeordnet ist, das die Wickelköpfe (5) und die Innenwandung (14) berührt und diese thermisch koppelt und hierzu einen Wärmeleitkoeffizienten größer als 1 W/mK aufweist.
