  • Percussion electrical hand held tool
    Patent number: 7048076
    Abstract: An electrical hand-held tool includes an electric motor (2) having a rotor shaft (3) extending transverse to the tool percussion axis (A), a rotor sheet stack (4) supported on the rotor shaft, and a pinion (5) supported on the rotor shaft, a percussion mechanism (6) including an eccentric (7), and a drive gear (8) engageable with the motor pinion (5) for driving the eccentric (7), with the rotor sheet stack (4) being arranged, with respect to the percussion axis A, completely diametrically opposite the drive gear (8).

  • Electrical, rotary-percussion hand-held tool
    Patent number: 6983807
    Abstract: An electrical, rotary-percussion hand-held includes a spindle (4), an electric motor for driving the spindle at different rotational speeds corresponding to different operational modes, a percussion mechanism and a gear mechanism arranged between the electric motor (1) and the spindle (4) for transmitting a drive torque from the electric motor (1) to the spindle (4), and a rotation shifting device (7) operatively connected with signal elements (6, 6?) and electrically connected with the electric motor (1) for driving the spindle (4) with a rotational speed corresponding to a selected operational mode.

  • Electrical, fan-cooled tool
    Patent number: 6866105
    Abstract: An electrical tool includes a housing having inlet (7) and outlet (8) openings, a brushless electric motor (2) and an inverted rectifier (3) both arranged in the housing (9) between inlet (7) and outlet (8) openings in an air stream (5) of an air volume (6), and a link condensator (10) located in the housing (9) in the air stream (5), with the inverted rectifier (3) being arranged, in the air flow direction, downstream of the link condensator (10) and upstream of the electric motor (2).

  • Electrical, rotary-percussion hand-held tool
    Publication number: 20040112615
    Abstract: An electrical, rotary-percussion hand-held including a spindle (4), an electric motor for driving the spindle between alternatingly switchable mode, a percussion mechanism and a gear mechanism arranged between the electric motor (1) and the spindle (4) for transmitting a drive torque from the electric motor (1) to the spindle (4), and a rotation shifting device (7) operatively connected with signal elements (6, 6′) and electrically connected with the electric motor (1) for actively shifting rotation of the spindle (4).
