Definitions

the invention relates to a safety routine and an associated rotating electric hand tool device, especially a drill, hammer drill or one Combi hammer.
the measurement of the torque acting on the housing is known from DE3128410A1 the handle leading the electric hand tool device is known.
About analog integration of a signal proportional to the torque is exceeded when a limit value is exceeded a safety device to avoid tool blocking, jamming and gagging activated.
the disadvantage is that it is necessary to build up the counterforce on the handle Management of the electric hand tool device by the user.
the invention has for its object a simple separation of the power transmission To show electrical hand tools.
Another aspect is another Solution to safely prevent an impermissibly high rotation of the housing of the Electric hand tool.
a collector and Slip ring-free electric motor for example a switched reluctance motor, especially in the case one registered by a sensor connected to the housing and a microcontroller, impermissible torsion to be expected in the future, via the engine control electronics decelerated with respect to the speed, which means if the clutch speed falls below one in the power transmission path between the electric motor and a transmission arranged, purely mechanical, centrifugal force-controlled clutch for transmitting the torque the power transmission separates.
the collector and slip ring-less which can be speed-controlled via motor control electronics Electric motors can be actively braked quickly, resulting in an impermissibly long time Follow-up can be prevented safely.
Another advantage of this solution is that there is no need for the safety routine needed used electromechanical coupling, reducing the weight and manufacturing costs can be reduced.
Fig. 1 as an electric hand tool device.
a hammer drill as an electric hand tool device 1 within a housing 2 a collector and slip ring-less speed-controllable via motor control electronics 3
Electric motor 4 in particular a switched reluctance motor, which in Power transmission path via a purely mechanical, speed-dependent clutch 5 for Transmission of the torque is connected to a gear 6.
Housing 2 with a sensor 7, evaluated by a microcontroller, for detection a future, impermissibly high, twist of the housing 2 connected.
