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.
