  • Patent number: 6651860
    Abstract: An electric tool device (1) for an at least partially rotating and percussive striking driving mechanism with a pneumatic striking mechanism (2), which is driven over a gear assembly (9) by an electronically commutated electric motor (3) with an internal rotor (5) having poles (4) and an external stator (8), having field coils (7) connected with a DC-AC converter of control electronics (6), the power take-off side of the rotor shaft (10) being mounted in the gear assembly (9) and the driving end of the rotor shaft (10) with the freely protruding poles (4) engaging the stator (8), being introduced coaxially into the stator (8).
