  • Patent number: 9041320
    Abstract: The invention relates to a portable work apparatus having a housing and a work tool which is driven by an electric motor via a gear assembly. A flywheel which rotates about a rotational axis is arranged in the drive train between the electric motor and the gear assembly, which flywheel is connected fixedly to an output shaft so as to rotate with it, which output shaft protrudes into a gear assembly space and has a drive pinion. The output, shaft and the flywheel are mounted in the housing by two bearing locations, the rotational axis of the flywheel and a motor shaft of the electric motor lying coaxially with respect to one another, and the motor shaft of the electric motor being connected fixedly to the flywheel so as to rotate with it. The electric motor is fixed in the housing exclusively via a torque support.

  • Patent number: 8353362
    Abstract: A hand-held power tool has a device housing and at least one grip disposed on the device housing. An electric drive motor is arranged in the device housing for operating a working tool. A battery pack provides electric energy for operating the electric drive motor. An electronic control unit is connected to the electric drive motor and the battery pack. An operating element disposed on the grip controls the electric drive motor. An electric actuator is acted upon by the operating element and the output signal of the electric actuator is supplied to the electronic control unit. Electric energy is applied to the electric drive motor by the electronic control unit as a function of a position of the operating element, wherein in a first dead travel range of the operating element that adjoins an inoperative position of the operating element the supplied electric energy is zero.
