Abstract

본 발명은 리니어모터에 관하여 개시한 것이다.The present invention relates to a linear motor.

본 발명에 따른 리니어모터는 고정자와 가동자를 포함하여 이루어진 리니어모터에 있어서, 상기 가동자는 2개의 영구자석이 각각 상기 고정자에 대해 나란하게 배치되고, 상기 각 영구자석의 일측에는 4극을 이루도록 코일이 권선된 제1철심코어가 결합되는 동시에 상기 각 영구자석의 타측에도 동일한 모듈을 이루도록 코일이 권선된 4극의 제2철심코어가 대칭적으로 결합하여 이루어지는 구조로 개량함으로써 단위면적당 자속밀도를 증가시켜 성능향상 및 소형경량화를 도모할 수 있도록 한 것이다.The linear motor according to the present invention includes a stator and a mover, wherein the mover has two permanent magnets arranged side by side with respect to the stator, and a coil is formed on one side of each permanent magnet to form four poles. The magnetic flux density per unit area is increased by improving the structure in which the coiled 4-pole second core cores are symmetrically coupled so that the wound first core cores are coupled to each other and form the same module on the other side of each permanent magnet. It is intended to improve performance and reduce weight.
