Abstract: A work apparatus includes a housing, an electric motor arranged in the housing, the electric motor including a rotor shaft driven rotationally about a rotor axis, an output shaft for driving a tool, the output shaft being connected with a form fit to the rotor shaft on a receptacle of the rotor shaft, and a flange supported on the housing. The rotor shaft is mounted rotatably via a rotor shaft bearing arranged in the flange, the rotor shaft bearing extending along a bearing section in the direction of the rotor axis, and wherein the output shaft extends at least as far as the bearing section of the rotor shaft bearing.

Abstract: A turbine wheel for an exhaust gas turbocharger may include a body composed of a TiAl alloy via at least one of metal injection moulding, selective laser melting and electron beam melting. The body may include a plurality of blades each having an outlet blade root and an outlet blade tip disposed radially away from a rotation axis with respect to the outlet blade root. The body may have a quotient Q of a diameter dS defined by each of the outlet blade tips to a diameter dN defined by each of the oulet blade roots corresponding to the following relationship: Q=dS/dN>3.85.

Abstract: An exhaust gas turbocharger includes a waste gate valve and an adjusting device for adjusting the waste gate valve. The adjusting device is connected to the waste gate valve and disposed on a housing of the exhaust gas turbocharger. The adjusting device is fastened to the housing of the exhaust gas turbocharger via an adjusting template.
