Turbo Compressor and Compressor System Comprising Such a Turbo Compressor

摘要

In order to improve a turbo compressor for air, comprising a compressor housing and an impeller arranged in the compressor housing as well as a drive motor with a stator and a rotor, on the rotor shaft of which the impeller is seated, in such a manner that the drive motor is cooled in an optimum manner it is suggested that the drive motor be cooled with a flow of cooling air by way of a closed cooling air circuit and the flow of cooling air in the cooling air circuit flow through at least one cooling bore which penetrates a section of the rotor shaft.
