Abstract
The present invention relates to a linear motor for a linear compressor reciprocating a moving member linearly inside a stationary member to compress refrigerant, and more particularly, to a linear motor for a linear compressor capable of decreasing an iron loss of a flux generated when a current flows in a coil and increasing an inductance. A linear motor for a linear compressor includes an inner stator formed by stacking core blocks in a circumference direction to be insulated from each other, an outer stator formed by arranging core blocks in a circumference direction at a predetermined intervals, and winding a coil around the core blocks, and a plurality of permanent magnets formed between the inner stator and the outer stator with a predetermined gap, and reciprocated linearly due to a mutual electromagnetic force.
