Abstract
(DE)
Bei dem Verfahren zum Sintern eines mehrkomponentigen Sinterzeugs wird eine mit einem ersten Material gebildete erste Komponente mit Ausnehmungen für eine zweite Komponente gedruckt und es wird eine mit einem zweiten Material gebildete zweite Komponente in die Ausnehmungen der ersten Komponente eingelegt wird und es werden erste und zweite Komponente mittels Sinterns aneinander angeschrumpft. Die Elektrische Maschine weist einen Rotor, gebildet aus mit einem Verfahren nach einem der vorhergehenden Ansprüche gefertigten Rotorblechen, auf. Das elektrische Fahrzeug ist insbesondere ein hybridelektrisches Flugzeug und weist eine solche elektrischen Maschine auf.
(EN)
The invention relates to a method for sintering a multicomponent object to be sintered. A first component made of a first material is printed with recesses for a second component, and the second component made of a second material is inserted into the recesses of the first component. The first and second component are shrunk fit onto each other by means of sintering. The electric machine has a rotor, which is made of rotor laminations produced using a method according to one of the aforementioned claims, and the electric vehicle is a hybrid electric airplane in particular and has such an electric machine.
(FR)
L'invention concerne un procédé de frittage d'un produit à fritter à plusieurs composants, selon lequel un premier composant formé avec un premier matériau est imprimé avec des évidements pour un deuxième composant et un deuxième composant formé avec un deuxième matériau est inséré dans les évidements du premier composant et les premier et deuxième composants sont serrés l'un sur l'autre par frittage. La machine électrique présente un rotor, formé de tôles de rotor fabriquées au moyen d'un procédé selon l'une des revendications précédentes. Le véhicule électrique est en particulier un avion électrique hybride et présente une machine électrique de ce type.
