Title
(DE) ELEKTRISCHER ANTRIEB
(EN) ELECTRIC DRIVE
(FR) ENTRAÎNEMENT ÉLECTRIQUE
Abstract
(DE)
Die Erfindung betrifft einen elektrischen Antrieb (1) mit einem kontaminierten Bereich (2) und einem Schutzbereich (3), in welchem eine Elektronik (4) angeordnet ist, wobei zwischen dem kontaminierten Bereich (2) und dem Schutzbereich (3) eine Dichtwand (5) vorhanden ist, durch welche eine elektrische Durchführung (6) verläuft. Aufgabe der Erfindung ist es eine Elektronik in einem Schutzraum vor eindringenden Schadmedien zu schützen und die Wärmeabfuhr aus dem Schutzraum zu verbessern. Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.
(EN)
The invention relates to an electric drive (1), comprising a contaminated region (2) and a protection region (3), in which electronics (4) are arranged, a sealing wall (5) being provided between the contaminated region (2) and the protection region (3), through which sealing wall an electrical feed-through (6) runs. The problem addressed by the invention is that of protecting electronics in a protection chamber from penetrating harmful media and improving the removal of heat from the protection chamber. According to the invention, said problem is solved by the features of claim 1.
(FR)
L’invention concerne un entraînement électrique (1) pourvu d’une zone contaminée (2) et d’une zone de protection (3), dans lequel est agencée une électronique (4), une paroi étanche (5) à travers laquelle s’étend un passage électrique (6) étant présente entre la zone contaminée (2) et la zone de protection (3). L’objet de l’invention est de protéger une électronique dans un espace de protection contre l’intrusion de milieux néfastes et d’améliorer la dissipation thermique de l’espace de protection. Cet objet est résolu selon l’invention par les caractéristiques de la revendication 1.
