ABSTRACT:
A closed-type compressor comprises a closed casing, an electric motor accommodated in the closed casing and comprising a stator and a rotor, and a compressing machine operatively connected to the motor to be driven thereby. The closed casing comprises a cylindrical body case portion and cover case portions for covering two-side opening portions of the body case portion so as to provide a three-piece structure and a wall thickness of the body case portion is made to be thicker than that of each of the cover case portions. The stator is provided with a stator core and secured in the closed casing in a state where the stator core is stacked and an axial length of the stator is made to be longer than a radius of the stator core. The closed-type compressor of the character described above is applicable to a refrigerating unit, refrigerator or air conditioner.
