PROBLEM TO BE SOLVED: To provide an enclosed electric compressor equipped with an outer rotor electric motor, suppressing the change in rotational speed by suppressing the winding wire resistance and current density and increasing the inertia moment of a rotor, and making a stable rotation which is small in runout of a rotary shaft and deflection by making the rotor's center of gravity closer to a copmression mechanism, and an refrigeration cycle device equipped with the enclosed electric compressor, enabling the improvement of refrigeration efficiency. SOLUTION: The electric motor 4 and a compression mechanism 3 are housed in an enclosed case 1. The electric motor is provided with a stator 9 in which an iron core is formed by laminating a plurality of magnetic steel sheets, a plurality of slots 50 are provided radially from the center of the iron core, and the slots are wound by coil 52; and the rotor 10 arranged at the outer peripheral side of the stator, and composed of an permanent magnet M and the iron core T laminated by a plurality of magnetic steel sheets. The ratio (D/H) of the rotor iron core's outer diameter D to a lamination thickness H is set to equal to 2.0 or more (D≥2H). COPYRIGHT: (C)2006,JPO&NCIPI
