A turbocompressor (1) has an electric motor (2), a multistage radial turbocompressor (3) and a common shaft (13). A section of the shaft (13) is formed as the armature (2b) of the electric motor (2) and a further section of the shaft (13) is formed as the rotor (3e) of the radial turbocompressor (3)

A turbocompressor (1) has an electric motor (2), a multistage radial turbocompressor (3) and a common shaft (13). A section of the shaft (13) is formed as the armature (2b) of the electric motor (2) and a further section of the shaft (13) is formed as the rotor (3e) of the radial turbocompressor (3), with the rotor (3e) including a compressor shaft and compressor wheels (3b) connected thereto. A plurality of electromagnetic radial bearings (5) are arranged spaced apart in the direction of the shaft (13) for the journalling of the shaft (13), and a single electromagnetic radial bearing (5) is arranged between the armature (2b) of the electric motor and the compressor wheel (36). The electric motor (2), the radial turbocompressor (3), the shaft (13) and the radial bearings (5) are inside a common housing sealed gas-tight to the outside. The housing (6) consists of a plurality of part housings (6e, 6f, 6g) which are connected together. The electric motor (2) is arranged in one part housing (6f) and the radial turbocompressor (3) in another part housing (6e, 6g). The armature (2b) of the electric motor (2) and the rotor (3e) of the radial turbocompressor (3) are connectable to form a common shaft (13) via a coupling (4) arranged between the armature (2b) of the electric motor (2) and the compressor wheel (36).
