Abstract (en)
[origin: WO2020260090A1] The invention relates to a method for operating a machine tool comprising a battery and an electric motor which is designed to rotationally drive an output shaft that can be coupled to a tool. A controller for actuating the electric motor and a device for ascertaining a parameter are provided, wherein the machine tool can be operated in a first operating mode and a second operating mode, and the machine tool is converted from the first operating mode to the second operating mode if the parameter ascertained by the device exceeds or falls below a defined threshold. The electric motor is actuated in the second operating mode with a current strength profile, said current strength profile comprising first current pulses (10) and second current pulses (11). The level of the maximum current strength (A1) of the first current pulses (10) is higher than the level of the maximum current strength (A2) of the second current pulses (11). The invention additionally relates to a machine tool which can be operated using such a method.
