摘要： A compensation of cyclical interferences occurring during operation of motor controlled by an electrical motor drive comprising the controllable motor and a speed governor, wherein a position determiner is provided for continuously determining a position of said motor, responsive to a position signal indicative of said position of said motor and wherein a load observer responsive to a first output signal received from said position determiner and to a second output signal received from the speed governor is provided for generating a load signal indicative of an estimated load and continuously applying said load signal to an output of the speed governor.

摘要： A motor driven hand power tool has a saw including a saw blade, a separating tool formed as a saw blade movable about a tilting axis extending parallel to a cutting line of sight and fixable in each turning position relative to a workpiece which is subdivided by a cutting joint into a product-side and a refuse-side with product and refuse-side cutting edges, a base plate over which the saw blade is positioned. The saw blade is arranged so that the tilting axis extends at a distance under a lower side of the base plate, and the distance is dimensioned so that the tilting axis in a working position of the power tool is located under an upper surface of the workpiece in an interior of the workpiece.
