Title: | Dynamic performance analysis of permanent magnet contactor with a flux-weakening control strategy | Authors: | Wang, X Lin, H Fang, S Jin, P Wang, J Ho, SL |
Issue Date: | 1-Apr-2011 | Source: | Journal of applied physics, 1 Apr. 2011, v. 109, no. 7, 07E707, p. 1-3 | Abstract: | A new flux-weakening control strategy for permanent magnet contactors is proposed. By matching the dynamic attraction force and the antiforce, the terminal velocity and collision energy of the movable iron in the closing process are significantly reduced. The movable iron displacement is estimated by detecting the closing voltage and current with the proposed control. A dynamic mathematical model is also established under four kinds of excitation scenarios. The attraction force and flux linkage are predicted by finite element method and the dynamics of the closing process is simulated using the 4th-order Runge-Kutta algorithm. Experiments are carried out on a 250A prototype with an intelligent control unit to verify the proposed control strategy | Keywords: | Contactors Finite element analysis Intelligent control Iron Magnetic flux Permanent magnets Pulse width modulation Runge-Kutta methods |
