Abstract
An electrical hand held tool for producing at least a percussion movement of a working tool includes an electrical drive, a first, oscillating subassembly including a percussion mechanism (2) and a rotor (5) of the electrical drive for transmitting torque to the percussion mechanism and rotatable about a rotor axis (B) extending parallel to an oscillation path (I) of the first subassembly, and a second subassembly including a housing (6) in which the first subassembly is supported for a limited oscillating movement along a tool axis (A).
Claims8
An electrical hand-held tool for producing at least a percussion movement of a working tool, comprising an electric drive;
- a first, oscillating subassembly including a percussion mechanism (2) for transmitting the percussion movement to the working tool, and a brushless rotor (5) of the electrical drive which is rotatable about a rotor axis (B) extending parallel to an oscillation path (I) of the first subassembly wherein the brushless rotor (5) also oscillates along the rotor axis;
- and a second subassembly including a stator (7) of the electrical drive and a housing (6) in which the first subassembly is supported for a limited oscillating movement along a tool axis (A) and relative to the second sub-assembly.
