Title (DE) HANDWERKZEUGMASCHINE
(EN) HAND-POWER TOOL
(FR) MACHINE-OUTIL PORTATIVE
Abstract:
(DE) Die Erfindung geht aus von einer Handwerkzeugmaschine mit zumindest einer Werkzeugspindel (12a; 12b) und einer Antriebseinheit (14a; 14b), die dazu vorgesehen ist, die Werkzeugspindel (12a; 12b) mit einer Drehzahl größer als 10 000 min-1 anzutreiben. Es wird vorgeschlagen, dass die Antriebseinheit (14a; 14b) einen bürstenlosen Elektromotor (30a) aufweist.
(EN) The invention relates to a hand-power tool comprising at least one tool spindle (12a; 12b) and a drive unit (14a; 14b) which is provided for driving the tool spindle (12a; 12b) at a rotational speed greater than 10,000 min-1. According to the invention, the drive unit (14a; 14b) has a brushless electric motor (30a).
(FR) La présente invention concerne une machine-outil portative comprenant au moins une broche porte-outil (12a; 12b) et une unité d'entraînement (14a; 14b) qui est conçue pour entraîner la broche porte-outil (12a; 12b) à un régime supérieur à 10 000 min-1. Selon l'invention, l’unité d'entraînement (14a; 14b) comprend un moteur électrique sans balais (30a).
