AXIAL FLOW COMPRESSOR

摘要

An axial flow compressor (10) comprises: an electric motor (22) having a rotating shaft (22a); a drive shaft (40) that is connected to the rotating shaft (22a) of the electric motor (22) without passing through a step-up gear; and a rotor (31) that rotates together with this drive shaft (40). The axial flow compressor (10) is also provided with a compressor unit (20) that compresses a working fluid by driving the drive shaft (40), and a deceleration portion (24) having a space for reducing the flow rate of the working fluid discharged from the discharge port of the compressor unit (20). The rotating shaft (22a) of the electric motor (22) is connected to the end on the discharge port side of the drive shaft (40), and the deceleration portion (24) is positioned so as to surround the electric motor (22).
