An electrical hand-held tool includes an electric motor () having a rotor shaft () extending transverse to the tool percussion axis (A), a rotor sheet stack () supported on the rotor shaft, and a pinion () supported on the rotor shaft, a percussion mechanism () including an eccentric (), and a drive gear () engageable with the motor pinion () for driving the eccentric (), with the rotor sheet stack () being arranged, with respect to the percussion axis A, completely diametrically opposite the drive gear ().

Percussion electrical hand held tool

An electrical, rotary-percussion hand-held includes a spindle (), 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 () and the spindle () for transmitting a drive torque from the electric motor () to the spindle (), and a rotation shifting device () operatively connected with signal elements (') and electrically connected with the electric motor () for driving the spindle () with a rotational speed corresponding to a selected operational mode.

Electrical, rotary-percussion hand-held tool

An electrical tool includes a housing having inlet () and outlet () openings, a brushless electric motor () and an inverted rectifier () both arranged in the housing () between inlet () and outlet () openings in an air stream () of an air volume (), and a link condensator () located in the housing () in the air stream (), with the inverted rectifier () being arranged, in the air flow direction, downstream of the link condensator () and upstream of the electric motor ().
