ANALYSIS OF MAGNETIC FIELD AND DYNAMIC BEHAVIOR OF THE PERMANENT MAGNETIC ACTUATOR

자계해석을 통한 영구자석형 차단기 조작기의 동작특성 해석

This paper formulates the principle of the permanent magnetic actuator (PMA) and its dynamic characteristic calculation. Some results of the calculation and analysis of the dynamic curves are presented. Due to its great advantages, PMA that presented recently drew great attention from engineers all over the world. We present the magnetic field and actuator using finite element method associated to parameter calculating the displacement of the moving parts and the supplying current when the actuator is DC voltage supplied or capacitor supplied. In this paper, We will do compare of dynamic behavior between DC voltage supplied and capacitor discharge supplied.
