Abstract

본 발명은 리니어 압축기의 리니어 모터 구조에 관한 것으로, 소정의 폭을 갖는 개구부가 형성되고 그 개구부의 폭 만큼 코일이 권회되는 제1고정자와, 상기 제1고정자에 대하여 소정의 갭이 유지되는 제2고정자와, 상기 개구부의 폭보다 큰 길이를 갖고 제1고정자 및 제2고정자 사이의 갭을 왕복 진선 이동하는 마그네트로 구성하여, 마그네트의 왕복 직선 이동시, 제1고정자의 개구부 전 폭 걸쳐마그네트가 항상 위치하도록 함으로써 리럭턴스의 변화에 의한 코깅력의 발생을 방지하며, 따라서, 마그네트의 동작 제어를 보다 용이하게 하고, 기전력 파형에 고조파 성분이 포함되는 현상을 방지하여 효율을 향상시키도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linear motor structure of a linear compressor, comprising: a first stator in which an opening having a predetermined width is formed and a coil wound around the width of the opening, and a second gap in which a predetermined gap is maintained with respect to the first stator. A stator and a magnet having a length greater than the width of the opening and having a reciprocating forward line move the gap between the first stator and the second stator so that the magnet is always positioned over the entire width of the opening of the first stator during the reciprocating linear movement of the magnet. This prevents the occurrence of cogging force due to the change in reluctance, thereby making it easier to control the operation of the magnet and to improve the efficiency by preventing the phenomenon in which harmonic components are included in the electromotive force waveform.
