Zusammenfassung:The present invention relates to a magnetic lift device, comprising: a permanent magnet that provides magnetic force to objects; a first pole piece in contact with one pole of the permanent magnet; a second pole piece in contact with the other pole of the permanent magnet; a third pole piece disposed below the first pole piece and spaced apart from the first pole piece by a predetermined distance; a fourth pole piece disposed below the second pole piece and spaced apart from the second pole piece by a predetermined distance; a rotor disposed between the first to fourth pole pieces and made of a magnetic material and a non-magnetic material; and a motor that rotates the rotor, thereby capable of controlling the magnetic force generated through permanent magnets and pole pieces using the rotor made of magnetic and non-magnetic materials. 본 발명은 마그네틱 리프트 장치에 관한 것으로서, 대상물에 자기력을 제공하는 영구자석; 상기 영구자석의 일 극에 접촉되는 제1 폴피스와, 상기 영구자석의 타 극에 접촉되는 제2 폴피스; 상기 제1 폴피스의 하부에 상기 제1 폴피스로부터 일정거리만큼 이격되어 배치되는 제3 폴피스와, 상기 제2 폴피스의 하부에 상기 제2 폴피스로부터 일정거리만큼 이격되어 배치되는 제4 폴피스; 상기 제1 폴피스 내지 제4 폴피스 사이에 배치되며, 자성체와 비자성체로 이루어진 회전자; 및 상기 회전자를 회전 구동하는 모터를 포함한다.
