Document Type and Number:
WIPO Patent Application WO/2016/092906
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a compressor with which it is possible to reduce the bending amount of a drive shaft and reduce the noise generated by vibration caused by a bending eigenvalue. This compressor is provided with: a compression mechanism; a motor that has a rotor (13) formed by laminating a plurality of steel sheets, and a stator (12) provided in an outer peripheral portion of the rotor (13); and a drive shaft (14) that connects the motor and the compression mechanism. A first balance weight (35) is provided on the rotor (13) on the surface that is on the opposite side from the compression mechanism side in terms of the axial direction of the drive shaft (14), and a steel sheet (13A) from among the laminated steel sheets that is on the first balance weight (35) side protrudes, with respect to the axis of the drive shaft (14), toward the stator (12) that is located on the opposite side from the first balance weight (35) in the radial direction of the rotor (13).
