Abstract
The present invention relates to a linear motor for a linear compressor that improves efficiency of a motor and simplifies a assembling process for a lamination by which the lamination is fixed by a fixing ring not by a welding process and lead wires are securely disposed. In a linear motor for a linear compressor for introducing and exhausting external gas by compressing, wherein there are an outer lamination and an inner lamination which is wound by a coil connect to lead wires and supported by inner coil springs, the linear motor according to the present invention includes: a lamination wherein protruding portions respectively having a caulking groove are formed at concentric circles of radially arrayed iron pieces, and a conductor connected lead wires which are connected to the coil is fixed thereto; and a non-magnetic fixing ring caulked in the caulking groove for preventing the iron pieces from being loosened.
