Abstract: PROBLEM TO BE SOLVED: To reduce noise of an electric compressor by decreasing the vibration transmission from a stator core to a sealed container. SOLUTION: In the sealed container, there are disposed: an electric motor 2 composed of a stator 22 and a rotor 24; and a compression mechanism part 3 driven by the electric motor 2. The circumference surface of the stator 22 is fixed to the inner wall of the sealed container 1. In this structure, a belt-like dent 41 is provided over the radial direction on the inner diameter side of the sealed container 1, to which the stator core 22a of the stator 22 abuts, so as to reduce the contact area of the inner wall of the sealed container 1 with the circumference surface of the stator 22.

Abstract: PROBLEM TO BE SOLVED: To reduce poor insertion in shrink-fit of a stator into a hermetic vessel even if an outer circumference of the stator is a round shape, reduce discharged oil quantity, inhibit drop of electric motor efficiency, and simultaneously improve thermal exchange capacity of refrigeration cycle and efficiency of the hermetic compressor.
SOLUTION: An inner diameter dimension B of an inner diameter cylinder part without a groove part 9 is set larger than an inner diameter dimension A of the inner diameter cylinder part of a groove part 9 provided on an inner wall of a hermetic vessel 1. Consequently, since the inner diameter dimension B of an opening part of the hermetic vessel 1 is larger than an outer diameter dimension of the stator 22, axial length of a section touching the hermetic vessel 1 becomes short and the stator 22 can be smoothly inserted when the stator 22 is inserted. Simultaneously, discharged oil quantity is reduced, drop of electric motor efficiency is inhibited, heat exchange capacity of the refrigeration cycle and efficiency of the hermetic compressor are simultaneously improved.
