Abstract[German]
Die vorliegende Erfindung betrifft eine elektrische Maschine (1) mit einem Stator (2) und einer an demselben um eine Drehachse (3) herum drehverstellbar gelagerten Rotorwelle (4), mit einer am Stator (2) angeordneten Primärspule (5) sowie einer an der Rotorwelle (4) angeordneten Sekundärspule (6), die im Betrieb der elektrischen Maschine (1) mit der Primärspule (5) induktiv gekoppelt ist, sodass elektrische Energie von der Primärspule (5) auf die Sekundärspule (6) übertragen wird. Wesentlich für die Erfindung ist, dass die elektronischen Gleichrichterbauteile (9) einer Gleichrichtervorrichtung (7) innerhalb einer Aufnahme (15) eines Gleichrichtergehäuses (8) der Gleichrichtervorrichtung (7) angeordnet sind und von Kühlkanälen (17) des Gleichrichtergehäuses (8) indirekt gekühlt werden.[English]
The invention relates to an electric machine (1) comprising a stator (2), a rotor shaft (4) which is mounted on the stator in a rotationally adjustable manner about a rotational axis (3), a primary coil (5) arranged on the stator (2), and a secondary coil (6) which is arranged on the rotor shaft (4) and which is inductively coupled to the primary coil (5) during the operation of the electric machine (1) such that electric energy is transmitted from the primary coil (5) to the secondary coil (6). It is essential to the invention that the electronic rectifier components (9) of a rectifier device (7) are arranged within a receiving area (15) of a rectifier housing (8) of the rectifier device (7) and are indirectly cooled by cooling channels (17) of the rectifier housing (8).[French]
L'invention se rapporte à une machine électrique (1) comprenant un stator (2), un arbre de rotor (4) qui est monté sur le stator de manière réglable en rotation autour d'un axe de rotation (3), une bobine primaire (5) agencée sur le stator (2), et une bobine secondaire (6) qui est agencée sur l'arbre de rotor (4) et qui est couplée par induction à la bobine primaire (5) pendant le fonctionnement de la machine électrique (1) de telle sorte que l'énergie électrique soit transmise de la bobine primaire (5) à la bobine secondaire (6). Selon l'invention, il est essentiel que les composants redresseurs électroniques (9) d'un dispositif redresseur (7) soient agencés à l'intérieur d'une zone de réception (15) d'un logement de redresseur (8) du dispositif redresseur (7) et soient indirectement refroidis par des canaux de refroidissement (17) du logement de redresseur (8).
