Abstract

L'invention concerne un dispositif de machine-outil (12) conçu pour une machine-outil (10), en particulier une machine-outil portative (10), comprenant au moins une unité d'accouplement (18) servant à l'accouplement d'un outil d'usinage (14) et au moins une unité d'entraînement (16) servant à l'entraînement de cette unité d'accouplement (18). Selon l'invention, le dispositif de machine-outil (12) comprend une unité de récupération (24) qui, lorsque l'unité d'entraînement (16) se trouve dans au moins un état désactivé, fournit, au moins à l'unité d'accouplement (18), une énergie électrique pour alimenter au moins une unité fonctionnelle (36), à partir d'une énergie cinétique.
