PURPOSE:To certainly cool a motor by arranging a suction pipe into the shell trunk part corresponding to the core accumulation and introducing the inhaled gas into the suction side of a compression mechanism through a circulation passage outside a stator. CONSTITUTION:A suction pipe 24 connected to a sealed shell is installed at the position corresponding to between the motor core accumulation, and a circulation passage 31 for the pass of the gas inhaled from suction pipe 24 is formed between the outer peripheral wall surface 29 of a motor stator 13a and the inner wall surface 30 of the shell opposed to the wall surface 29. The inhaled gas which uniformly cools the motor stator 13a, passing through the inside of the circulation passage 31 is inhaled into the suction chamber 6 of a compression mechanism through a flow passage 26 formed between a bearing frame and a shell 22.
