영구자석 재질에 따른 리니어 왕복 액추에이터의 특성 분석

This paper deals with the design and characteristic analysis of linear oscillatory actuator (LOA) according to permanent magnet material. NdFeB magnet have been widely used, but the main drawback to it is the high price. Therefore, research about material which substitutes NdFeB magnet has resurfaced. This paper shows the design and characteristic analysis of LOA designed by low cost Ferrite, and compares LOA designed by NdFeB magnet to it using Finite Element Method (FEM). Lastly, It verified the validity that Ferrite magnet is seen as the alternative to NdFeB magnet.
