Abstract
An armature of a linear motor includes a plurality of cooling pipe storage holes formed along a longitudinal direction of a core, and a plurality of cooling pipes stored vertically in the cooling pipe storage holes and having a meander shape. The cooling pipes vertically adjacent to each other are arranged such that inlets and outlets of the cooling pipes are alternately connected in parallel to a refrigerant inlet and a refrigerant outlet in order to allow a refrigerant to flow in the reverse direction.
