Title
(DE) ELEKTRISCHES ANTRIEBSSYSTEM
(EN) ELECTRIC DRIVE SYSTEM
(FR) SYSTÈME D'ENTRAÎNEMENT ÉLECTRIQUE
Abstract
(DE) Elektrisches Antriebssystem mit einem Rotorring (1), an welchem Magneten (1a) angeordnet sind und an welchem ein Flansch (1b) mit Bohrungen (17) zur Befestigung eines Propellers oder einer Welle angebracht ist, und welcher in einem Statorzentralstück (2) gelagert ist, das auch zur Befestigung des elektrischen Antriebssystems an einem Motorträger dient, weist weiter ein Eisenblechpaket (2b) auf, welches mit dem Stator (2) über Lamellenstege (3) verbunden ist und Statorwicklungen (3a) aufweist, die auf Zähne (8) des Eisenblechpaketes (2b) aufgewickelt sind.
(EN) Disclosed is an electric drive system comprising a rotor ring (1) on which magnets (1a) are arranged and on which a flange (1b) is mounted that has bores (17) for securing a propeller or a shaft. The rotor ring (1) is mounted in a central stator piece (2) which is also used for securing the electric drive system to a motor support. The electric drive system further comprises a sheet iron stack (2b) that is connected to the stator (2) via lamellar webs (3) and has stator windings (3a) which are coiled onto teeth of the sheet iron stack (2b).
(FR) La présente invention concerne un système d'entraînement électrique comprenant une bague de rotor (1) sur laquelle se trouvent des aimants (1a) et sur laquelle est mis en place un collet (1b) présentant des orifices (17) destinés à la fixation d'une hélice ou d'un arbre, et au centre de laquelle est montée une pièce centrale de stator (2) qui sert également à la fixation du système d'entraînement électrique à un support moteur. Selon l'invention, le système présente également un paquet de tôles de fer (2b) qui est relié au stator (2) par des tiges lamellaires (3) et présente des enroulements de stator (3a) qui sont enroulés sur les dents du paquet de tôles de fer (2b).
