Abstract: In this paper, a design scheme for a novel energy-saving contactor using two-phase magnetic material is presented. A magnetization model using two-phase magnetic material was built with mathematical modeling and the theory of the Preisach model. The conversion mechanism was analyzed in order to reveal the relationship between the remanence and coercivity. The manufacturing process of the material is also described. Based on the differences between the transformation characteristics of the two-phase magnetic material in the permanent magnet and the soft magnetic field, an energy-saving contactor was designed by using two-phase magnetic material based on the remnant magnetism of 75 Oe. The simulation and experiment results show that the proposed energy-saving contactor functions well.
Keywords: Two-phase magnetic material, hysteresis model, energy-saving contactor
