ABSTRACT:
A compressor includes a compression mechanism, a motor coupled to the compression mechanism via a driving shaft, and a casing to accommodate the compression mechanism and the motor. The motor includes a stator, and a rotor disposed inside the stator and coupled to the driving shaft. The stator is spot-joined to the casing via a plurality of stator spot-joined portions at different positions along a circumferential direction about the driving shaft. Preferably, the stator spot-joined portions are disposed at different axial positions. Also, the stator spot-joined portions are preferably disposed at different circumferential positions from positions of compression mechanism-side spot-joined portions. When an accumulator is connected to the casing via a connection pipe, a straight line between any two of the plurality of stator spot-joined portions preferably crosses a vibration direction of a natural vibration mode of the accumulator.
