A handheld blower apparatus includes a housing (), an axial blower () which conveys air through a blower tube (), and an electric drive motor (). The drive motor () has a rotor () and a stator () and rotatably drives a drive shaft () and at least one fan wheel () of the axial blower (). A simple construction results when the drive shaft () is rotatably mounted in the housing (), when the rotor () of the drive motor () is connected to the drive shaft () in a rotatably fixed manner and the stator () of the drive motor () is rotatably mounted on the drive shaft (). The stator () is supported relative to the housing () to prevent rotation and can tilt in a limited manner relative to the housing ().

Handheld blower apparatus

A handheld work apparatus having an electric drive motor has a battery pack () serving as a power supply unit for the drive motor. A receptacle for the battery pack () is provided on a housing () of the work apparatus. In order to simplify the mounting and arrange the battery pack () in a more favorable manner, a receiving compartment is provided in the housing () and a system carrier is arranged therein, to which electrical components () and electrical lines are affixed. A battery compartment () is formed in the system carrier () and contact elements for contacting the battery pack () are arranged on the system carrier (). The electrical components () are interconnected and connected to the contact elements () by the lines located on the system carrier ().

Handheld work apparatus having an electric drive motor

The invention relates to a blower apparatus () having a blower wheel () for generating a blower air flow (). The blower wheel () is arranged in a housing (), wherein the blower wheel is driven by an electric drive motor (). A blower tube () via which the generated blower air flow () is guided connects at an outlet (). A control unit () is provided for controlling the rotational speed of the electric drive motor. For a quick reduction of the blower air flow (), it is provided that the control unit () supports the deceleration of the drive motor () through a braking current (I).
