Abstract (en)
[origin: CA2312081A1] Turbocompressor (1) comprising an electric motor (2), a multistage radial turbocompressor (3) and also a common shaft (13), with a part section of the shaft (13) being formed as the armature (2b) of the electric motor (2) and wherein a further part section of the shaft (13) is formed as the rotor (3e) of the radial turbocornpressor (3), with the rotor (3e) including a compressor shaft and also compressor wheels (3b) connected therewith, and wherein a plurality of electromagnetic radial bearings (5) are arranged spaced apart in the direction of extent of the shaft (13) for the journalling of the shaft (13), and wherein a single electromagnetic radial bearing (5) is arranged between the armature (2b) of the electric motor and the compressor wheel (36), and wherein the electric motor (2), the radial turbocompressor (3), the shaft (13)and also the radial bearings (5), are arranged in a common housing sealed in gas-tight manner relative to the outside, characterised in that the housing (6) consists of a plurality of part housings (6e, 6f, 6g) which can be fixedly connected together, in that the electric motor (2) is arranged in one part housing (6f) and the radial turbocompressor (3) in one part housing (6e, 6g) and in that the armature (2b) of the electric motor (2) and also the rotor (3e) of the-radialturbocompressor (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).</SDOA B>
