PURPOSE:To improve the heat efficiency and aim at the compactness by housing a flat rotor and a compression mechanism member in an enclosed container, while providing a stator opposing to the flat rotor outside of the enclosed container, thereby composing an electric motor member of the rotor and the stator. CONSTITUTION:A compression mechanism member 2 composed of upper and lower bearings 3, 4, a cylinder 5, a roller 6, a crank shaft 7 and a vane or the like are housed in an under cover 1b of an enclosed container 1. A flat rotor 10 is pressure-fitted to an upper end of the crank shaft 7. An upper cover 1a is connected with the under cover 1b on the upper side of the flat rotor 10, while a stator 11 is opposed to the flat rotor 10 on the upper side of the upper cover 1a. An electric motor member 12 is formed with the flat rotor 10 and the stator 11. On the other hand, in the enclosed container 1, at least the upper cover 1a located in the opposite position to/between the flat rotor 10 and the stator 11 is formed of a permeable metal. |
