Abstract
An enclosed type electric compressor comprising an electric motor, a compressor and an enclosing vessel that contains said electric motor and said compressor therein, wherein a drive spindle of said compressor is linked with a rotor of said electric motor, said drive spindle is supported and a fixing member that is an element of said compressor is pressed into and fixed at the outer periphery of one end of a stator of said electric motor, a bearing frame by which the other end of said drive spindle is supported is pressed into and fixed at the outer periphery of the other end of said stator, and said fixing member and the outer peripheral portion of said pressing and fixing part of said stator on said bearing frame are pressed into and fixed on the inner wall of said enclosing vessel, said respective component parts being concentric so that the axial centers thereof are aligned with each other, so that scattering of the clearance between the stator and the rotor can be decreased, thereby causing balance of electromagnetic attraction force operating therebetween to be maintained and preventing abnormal overload and abnormal vibrations due to biased electromagnetic attraction force, and thus the compressor has high compression efficiency, excellent durability, low vibration, and little noise.
