A turbocompressor assembly (10) which is divided along an axis (12) of a rotor (11) into at least three sections (13,18,22), a bearing section (13) having at least one active magnetic bearing (14), a motor section (18) comprising a motor (19) having a stator (20) arranged along the axis (12) of the rotor (11), the stator enclosing a circumferential motor gap (21) formed between the stator and the rotor, a compressor section (22) having a compressor (23) for compressing a cooling fluid (30), a gas-tight housing (26) enclosing the rotor, the bearing section, the motor section and the compressor section and a cooling system (27) having an inlet (28) for supplying the pressurized cooling fluid (30) to the bearing section and the motor section through a fluid channel (29) positioned between the bearing section and the motor section, characterized in that the cooling system further comprises a throttling means (31) positioned adjacent to the motor gap for limiting the flow of cooling fluid from the fluid channel to the motor gap. |
