Abstract
In one aspect of the present invention, a stator of a linear compressor comprises first stator pieces that are circumferentially and sequentially arranged about an axial direction and are radially disposed, second stator pieces that are provided between outer parts of the adjacent first stator pieces, and an outer side, away from a motor axis, of the second stator pieces assembled at an outer circumference of the stator. The stator can reduce the magnetic losses of the stator caused by the gap, and improve the efficiency of the motor. It can also improve the performance, stability, durability and reliability of the linear compressor. It can also reduce the bulk of the linear compressor.
