<P>PROBLEM TO BE SOLVED: To provide a compressor that still has demagnetization resistance even with a smaller amount of DY (dysprosium) contained in rare earth magnet used in an electric motor, and prevents the increase of loss in an inverter main circuit for driving the electric motor. <P>SOLUTION: The compressor includes: a compression component for compressing a refrigerant; a six-pole motor for driving the compression component, and having a rotor using neodymium rare earth magnet including iron, neodymium, boron, and dysprosium of 4 wt.% or less; and a driving circuit for driving the electric motor, and using a SiC component in a switching part of an inverter main circuit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
