ABSTRACT:
An outer stator of a motor is mounted in a linear compressor for compressing a coolant gas. The outer stator comprises a coil assembly having a coil wound on a bobbin with flange parts and a plurality of core blocks that surround the coil assembly. The flange parts of the bobbin are provided with bobbin pressers that include protrusions so that the core blocks and the bobbin are pressed by a cylinder block and a back cover mounted in the linear compressor when the outer stator is in the linear compressor. The core blocks and the coil assembly of the outer stator are assembled in the linear compressor while the core blocks and the coil assembly of the outer stator are integrally attached to each other. Consequently, relative movement between the coil assembly and the core blocks is effectively prevented when the linear compressor is operated. Furthermore, shifting of coil wound on the bobbin is effectively prevented.
