Beschreibung
Zusammenfassung:	A method for braking a rotating tool of an electric machine tool, wherein the electric machine tool includes a machine electronics system and a motor. A braking method in which the braking process includes sub-sequences for feeding back the released braking energy and for driving the electric motor. The braking method is characterized by a changeover between the sub-sequences, wherein the changeover can either be initiated as a function of a voltage in an intermediate circuit of the machine electronics system. An invention relates to an electric machine tool for carrying out the braking method is also provided. The electric machine tool may be, in particular, an electric grinder.
