A linear compressor is provided. The linear compressor may include a cylinder that forms a compression space for a refrigerant, a piston that reciprocates in an axial direction inside of the cylinder, and a linear motor that supplies power to the piston. The linear motor may include an outer stator including a first stator magnetic pole, a second stator magnetic pole, and an opening defined between the first stator magnetic pole and the second stator magnetic pole; an inner stator disposed apart from the outer stator to form an air gap therebetween; and a permanent magnet movably disposed in the air gap between the outer stator and the inner stator and having three poles. The three poles may include two end magnetic poles, and a central magnetic pole disposed between the two end magnetic poles. The piston may be moveable by a stroke between a top dead center position and a bottom dead center position, and a length of the first stator magnetic pole or the second stator magnetic pole may be greater than a length of the stroke. |

1. A linear compressor, comprising:
a cylinder that forms a compression space for a refrigerant; a piston that reciprocates in an axial direction inside of the cylinder; and a linear motor that supplies power to the piston, wherein the linear motor comprises:
an outer stator comprising a first stator magnetic pole, a second stator magnetic pole, and an opening defined between the first stator magnetic pole and the second stator magnetic pole;an inner stator disposed apart from the outer stator to form an air gap therebetween; anda permanent magnet movably disposed in the air gap between the outer stator and the inner stator and having three poles, wherein the three poles include:
two end magnetic poles; anda central magnetic pole disposed between the two end magnetic poles, wherein the piston is moveable by a stroke between a top dead center position and a bottom dead center position, and wherein a length of the first stator magnetic pole or the second stator magnetic pole is greater than a length of the stroke. |
