Abstract (en)
[origin: WO2015192994A1] The invention relates to a hand-held machine tool (10), in particular an angle grinder, comprising an electric-motor drive (12) which has an electronically commutated electric motor (12), said electric-motor drive being provided to drive a machining tool (22), and having a machining tool (22). It is proposed that the electronically commutated electric motor (12) has an outer diameter dmotor, wherein the ratio of the outer diameter dmotor of the electronically commutated electric motor (12) to a diameter dtool of the machining tool (22) is a maximum of 0.42, in particular a maximum of 0.39, although preferably a maximum of 0.32.
