Zusammenfassung: | To restrain vibration of an electric motor from being transmitted to a compression mechanism part.SOLUTION: A hermetic electric compressor (scroll compressor S) comprises: an electric motor 2 comprising a stator 2a and a rotor 2b; a compression mechanism part 3 to be driven by the electric motor, and for compressing working fluid; a rotating shaft (crankshaft 6) for transmitting torque of the rotor to a movable part of the compression mechanism part; a supporting member (supporting plate 30) for supporting the stator; and a closed container 1 for housing the electric motor, the compression mechanism part, the rotating shaft, and the supporting member. The rotor is rotatably arranged on an outer peripheral side of the stator. The supporting member is welded and fixed to the closed container. The stator and the supporting member have shapes not in contact with the rotating shaft.SELECTED DRAWING: Figure 1
【課題】電動機の振動が圧縮機構部に伝達されることを抑制する。【解決手段】密閉型電動圧縮機(スクロール圧縮機S)は、固定子2aと回転子2bとを有する電動機2と、電動機により駆動され、作動流体を圧縮する圧縮機構部3と、回転子の回転力を圧縮機構部の可動部に伝達する回転軸(クランクシャフト6)と、固定子を支持する支持部材(支え板30)と、電動機と圧縮機構部と回転軸と支持部材とを収容する密閉容器1と、を備えている。回転子は、固定子の外周側に回転可能に配置されている。支持部材は、密閉容器に溶接固定されている。固定子と支持部材とは、回転軸に対して非接触な形状になっている。【選択図】図1 |
