Abstract: 본발명은스크롤압축기에관한것으로, 내부에냉매를압축하는압축부와, 상기압축부에구동력을제공하는구동모터를구비한구동부가설치되는메인하우징; 및상기메인하우징에결합되어수용공간을형성하는인버터커버와, 상기수용공간내부에설치되고전원공급회로가구비되는 PCB와, 상기메인하우징의전면에결합되어상기 PCB와상기구동부를전기적으로연결하는복수의개별기밀단자를구비한인버터어셈블리;를포함한다. 본발명에따르면, 모터에전원을공급하기위한 3상리드선과각각연결되는 3개의기밀단자가구비되리드선을한쪽으로모아인출하지않아도되므로모터의구조가간단해지는장점이있다.

Abstract: Provided is a linear compressor. The linear compressor includes a cylinder defining a compression space for a refrigerant, a piston reciprocated in an axis direction within the cylinder, and a linear motor providing power to the piston. The linear motor includes an inner stator disposed outside the cylinder, the inner stator including a center core and a side core disposed on at least one side of the center core, an outer stator disposed to be spaced outward from the inner stator in a radius direction, a permanent magnet movably disposed in an air gap defined between the inner stator and the outer stator, and a deformation prevention device for preventing the inner stator from being deformed.
