PROBLEM TO BE SOLVED: To provide a highly efficient inverter control type enclosed compressor having an effect to improve a reducing effect of power consumption in a low-rotational range of a cooling system. SOLUTION: When wire diameter of motor wiring 113b is represented by D and wire length of each of a phase U, a phase V and a phase W is represented by L, a value of L/D is set to be 180 to 400. Due to this, a motor torque constant is increased, and impressed current to an electric element 115 and impressed current to an inverter control circuit are reduced. Therefore, the total efficiency of the compressor, including inverter circuit loss, is improved. COPYRIGHT: (C)2007,JPO&INPIT
