Stator of linear motor

Abstract

In a stator of a linear motor having a plurality of outer core blocks, each of the outer core blocks comprises first and second side core blocks and a center core block. The center core block has an inner diameter equal to an outer diameter of a coil block. Consequently, insulation and heat transfer efficiencies are improved, and the size of the linear motor is minimized. Furthermore, the center core block is provided with a heat sink part, which is inserted in a coil block for dissipating heat from the coil block. Consequently, heat generated from the coil block is effectively dissipated.

Description

technical field [0001] The present invention relates to a linear motor, and more particularly, to a stator for a linear motor having a plurality of outer cores, wherein each outer core includes first and second side cores and a middle core, and the The inner diameter of the intermediate core block is equal to the outer diameter of the coil assembly, thus improving insulation and heat transfer efficiency and minimizing the volume of the linear motor. Background technique [0002] Generally, a linear compressor is a device that sucks, compresses, and discharges refrigerant gas (hereinafter referred to as "fluid") through the linear reciprocating motion of a piston in a cylinder, which is driven by a linear driving force of a linear motor. implemented.
