Abstract (en)
[origin: EP3217014A1] A compressor is provided that is capable of reducing a bending amount of a drive shaft to reduce noise generated by vibration caused by a bending eigenvalue. The compressor is provided with: a compression mechanism; a motor that includes a rotor (13) formed by a plurality of steel plates stacked on top of each other, and a stator (12) provided around an outer circumferential 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 surface of the rotor located remote from the compression mechanism in the axial direction of the drive shaft (14), and of the stacked steel plates, a steel plate (13A) adjacent to the first balance weight (35) protrudes toward the stator (12) located remote from the first balance weight (35) in the radial direction of the rotor (13) with respect to the axis of the drive shaft (14).
