A turbocompressor system comprising a high speed motor (10) comprising a rotor (12) mounted in a rotative manner relative to the stator, whereby on said rotor (12) one or more impellers (11) are directly fixed, said stator comprising active motor structures and a shell (7), comprising a ferromagnetic stator core (6) and a winding being constructed as toroidally wound coils (5), said shell (7) being constructed in such a manner as to create additional open space between said stator core (6) and said shell (7), constituting a cooling channel (15) through which process gas is passed axially for directly cooling said active motor structures and the rotor (12), prior to compression by said one or more impellers (11). |
