<P>PROBLEM TO BE SOLVED: To provide a compressor having a rotor with a permanent magnet embedded therein, configured to reduce electromagnetic noise. <P>SOLUTION: The compressor includes a stator and a rotor core 31 disposed inside the stator. The rotor core 31 is formed by laminating a plurality of thin plates, and includes a plurality of magnetic poles 51 each having holes 31a with magnets 32 and provided in the circumferential direction. At least one of the plurality of thin plates has cutouts 52 provided at a part corresponding to an outer circumference of the magnetic pole 51. The circumferential width of the cutout 52 is increased radially outward, and an end edge part near an end of the cutout 52 is tilted with respect to the radial direction at an end in plan view. <P>COPYRIGHT: (C)2013,JPO&INPIT |
