摘要： A handheld electric machine tool is described including a housing with a grip area, a tool area for a tool that is drivable in a linear and/or oscillating manner, an operating part on the housing for activation of the tool and/or the electric machine tool by the user, a drive unit disposed in the housing for producing a working motion of the tool, an electronic unit disposed in the housing for acting upon the drive unit with at least control and/or regulating signals, an operating voltage unit for supplying an electrical DC voltage, the drive unit including at least one excitation actuator having a volume of excitation-active material, which excitation actuator when in operation is electrically supplied by the operating voltage unit, is controlled or regulated by the electronic unit. The electronic unit may be configured to operate the at least one excitation actuator in a resonant frequency.
