COMPRESSOR AND FREEZER

To provide a compressor which can adjust a load applied to a bearing during rotation of a rotary shaft.SOLUTION: A compressor includes: a bearing; a rotary shaft which contacts with the bearing directly or through an oil; a motor which has a rotor fastened to the rotary shaft and a stator disposed so as to face the rotor in a radial direction and which rotates the rotary shaft; a compression mechanism which is driven by rotation of the rotary shaft; and a change part which changes a thrust load applied from the motor to the rotary shaft in an axial direction during the rotation of the rotary shaft.SELECTED DRAWING: Figure 5 【課題】軸受に加わる荷重を回転軸の回転中に調整可能な圧縮機の提供。【解決手段】軸受と、前記軸受に直接又は油を介して接触する回転軸と、前記回転軸に締結されたロータと、前記ロータと径方向で対向するように配置されたステータとを有し、前記回転軸を回転させるモータと、前記回転軸の回転により駆動される圧縮機構と、前記モータから前記回転軸に対して軸方向に加えるスラスト荷重を、前記回転軸の回転中に変更する変更部と、備える、圧縮機。【選択図】図５
