摘要:
AbstractIn the present paper d.c. contactors without economy apparatus re andlyzed. Such devices r quire a careful design of pole shape and an accurate prediction of the dynamical behaviour In order to avoid contact bouncing. Therefore the device analysIs is carried out by a model-ing procedure. In particular, the magnetic field in the dnving electromagnet is evaluated employing a two-dimensional nonlinear finite element technique. The dynamical behaviour of the device is predicted by solving the system of motional and circuIt nonlinear differential equations. The comparison between computational and experimental results shows some discrepan-Clea. Anyway, the procedure allows to satisfactorIly design the pole nhape and to give an approximate estimation ot the critical values of supply voltage.
