Abstract

본 발명은 리니어 압축기의 모터에 관한 것으로, 코일(21)의 권회량이 증대되는 만큼 코일 슬롯의 폭을 좁히도록 구성함으로써 일반적으로 영구자석(14)의 축방향 길이(L)가 적층철심(12)의 코일 슬롯(coil slot)의 폭을 Wc, 모터(M)의 스트로크(stroke)를 s라 할때, L=Wc+s 이므로, 모터(M)의 효율을 향상시키기 위해서는 코일(11)의 권회량을 증대시켜야만 하는데, 이와 같이 코일(11)의 권회량이 증대되면 코일의 폭(Wc)이 커져서 마그네트(16)의 축방향의 길이가 증가하게 되어 마그네트(16)의 사용량이 많아지게 되는 문제를 해소하여 코일(21)의 권회량을 증대시키더라도 코일 슬롯의 입구폭을 좁혀줌으로써 영구자석(24)의 길이를 늘려주지 않은 상태로 모터의 효율을 극대화시켰고, 영구자석(24)의 사용량이 증대되지 않아 모터의 효율이 향상되면서도 제조 비용은 절감되도록 한 것이다.The present invention relates to a motor of a linear compressor and is constructed such that the width of a coil slot is narrowed as the amount of winding of the coil is increased so that the axial length L of the permanent magnet 14 is generally smaller than the axial length L of the laminated iron core 12 Wc is the width of the coil slot of the coil 11 and s is the stroke of the motor M. In order to improve the efficiency of the motor M, If the winding amount of the coil 11 is increased as described above, the width Wc of the coil is increased and the length of the magnet 16 in the axial direction is increased to increase the amount of the magnet 16 used It is possible to maximize the efficiency of the motor without increasing the length of the permanent magnet 24 by narrowing the entrance width of the coil slot even if the amount of winding of the coil 21 is increased, The efficiency of the motor is improved and the manufacturing cost is reduced .
