Abstract

The present invention relates to a turbo compressor system having a cooling system for driving motors so as to efficiently cool at least two driving motors and, more specifically, to a turbo compressor system comprising a direct-drive turbo compressor for a high-speed motor. The turbo compressor system having at least two driving motors, according to one embodiment of the present invention, comprises: a first impeller, a second impeller, and a third impeller which are provided separate from one another; at least two driving motors for rotationally driving the first impeller, the second impeller, and / or the third impeller; and one cooling impeller for simultaneously cooling the at least two driving motors, wherein the cooling impeller can be connected to one rotary shaft of the at least two driving motors so as to be rotated. However, the turbo compressor system having the two or more driving motors, according to another embodiment of the present invention, can further comprise a fan motor which is provided separate from the two or more driving motors, and which is configured to rotate the cooling impeller.

Description

technical field [0001] The present invention relates to a turbocompression system having two or more drive motors, and more particularly to a turbocompression system having a motor cooling system for efficient cooling of two or more drive motors in a gearless type turbocompressor . Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Generally, a conventional turbo compressor is a device for compressing a gas such as air or refrigerant. This conventional turbo compressor is characterized by a very high discharge pressure. [0004] US 6,398,517 discloses a two-stage turbocompression system with a gearless type turbocompressor, and US 7,044,718 discloses a three-stage turbocompression system with a twin Three-stage compression, and the compression efficiency is improved by a first-stage impeller coupled with a first drive motor, and a second-stage impeller and a third-stage ...
