A turbocompressor ( ) has an electric motor ( ), a multistage radial turbocompressor ( ) and a common shaft ( ). A section of the shaft ( ) is formed as the armature ( ) of the electric motor ( ) and a further section of the shaft ( ) is formed as the rotor ( ) of the radial turbocompressor ( ), with the rotor ( ) including a compressor shaft and compressor wheels ( ) connected thereto. A plurality of electromagnetic radial bearings ( ) are arranged spaced apart in the direction of the shaft ( ) for the journalling of the shaft ( ), and a single electromagnetic radial bearing ( ) is arranged between the armature ( ) of the electric motor and the compressor wheel ( ). The electric motor ( ), the radial turbocompressor ( ), the shaft ( ) and the radial bearings ( ) are inside a common housing sealed gas-tight to the outside. The housing ( ) consists of a plurality of part housings ( ) which are connected together. The electric motor ( ) is arranged in one part housing ( ) and the radial turbocompressor ( ) in another part housing ( ). The armature ( ) of the electric motor ( ) and the rotor ( ) of the radial turbocompressor ( ) are connectable to form a common shaft ( ) via a coupling ( ) arranged between the armature ( ) of the electric motor ( ) and the compressor wheel ( ).

Cooling system for electromagnetic bearings of a turbocompressor

A turbocompressor ( ) has an outwardly gas-tight housing ( ) within which an electric motor ( ) and a multistage radial turbocompressor ( ) are arranged on a common shaft ( ). For journalling the shaft ( ), electromagnetic radial bearings ( ) are arranged spaced apart in the direction of the shaft. A gas seal ( ) surrounding the shaft ( ) is arranged between the electric motor ( ) and the radial turbocompressor ( ) in order to seal off the electric motor ( ) with respect to the radial turbocompressor ( ). The electric motor ( ) has an inner space ( ) which is connected in a fluid-conducting manner to an outlet opening ( ) which passes through the housing.
