Abstract (en)
The present invention reduces compressive stress and magnetic loss during shrink-fitting or press-fitting of a stator, and improves motor efficiency, without the need to change the shape of a stator core of the stator and without significantly enlarging a sealed housing. A hermetic electric compressor (1) in which an electric motor (5) and a compression mechanism (6) are fixedly installed within a cylindrical sealed housing (2) and the compression mechanism (6) can be driven by the electric motor (5) via a drive shaft (13), wherein the electric motor (5) is fixedly installed by shrink-fitting or press-fitting only a partial range (h1 to h5) of the stator (11) in its thickness direction to an inner peripheral surface of the sealed housing (2), and the remaining portion of the stator is in non-contact with the inner peripheral surface of the housing by increasing the inner diameter of the sealed housing (2).
