Abstract

The invention relates to a turbo compressor for air which comprises a compressor housing and a bladed wheel arranged inside the compressor housing and a drive motor having a stator and a rotor on the rotor shaft of which the bladed wheel is arranged, In order to improve said turbo compressor such that the drive motor is optimally cooled, the drive motor is cooled by a closed cooling air circuit having a cooling air flow and the cooling air flow in said cooling air circuit flows through at least one cooling bore that extends through a section of the rotor shaft.

Description

technical field [0001] The invention relates to a turbocompressor 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, the impeller being mounted on a rotor shaft of the rotor. Background technique [0002] Such turbocompressors are known from the prior art. [0003] In turbocompressors of this type, the drive motor is usually cooled in such a way that a flow of cooling air is blown over the drive motor. [0004] However, this results in a considerable load of dust on the drive motor and, on the other hand, the problem that unwanted impurities are entrained into the drive motor and into the environment. Contents of the invention [0005] It is therefore the object of the invention to improve the turbocompressor in such a way that the drive motor is cooled in an optimal manner. [0006] According to the invention, said object is solved in the turbocompressor according to the class ...
