Abstract
A compressor includes a closed container, a motor, and a compression mechanism arranged below the motor in the closed container and configured to be driven by the motor to compress a refrigerant The motor has a rotor arranged in the closed container and provided on a shaft extending in an up-down direction, and a stator fixed to the closed container. The compressor has a circulation amount of 1000 (kg/hr) or more in an operation at a maximum number of revolutions. The stator includes a stator core provided with a core cut serving as a passage of the refrigerant between an inner wall of the closed container and the stator. In the compressor, (pressure loss that occurs between an inlet and an outlet of the core cut)/(a gas density of the refrigerant−a density of a lubricant) is 1.45 or less.
