Abstract
A linear compressor can prevent leakage of a magnetic force by changing the construction of a linear motor. As the construction of the linear motor is changed, a mechanical spring constant is set smaller in consideration of a magnetic spring constant, so that the size of springs supporting a piston in the reciprocal linear motion direction can be reduced and components supporting the springs can be removed. Therefore, the linear compressor achieves a small size/a light weight. With the characteristics of the linear motor construction, the linear compressor can suppress a stroke spreading influence and easily expand a compression capacity according to a load.
