Parameter design of magnetic latching relays

Abstract

Based on the magnetic circuit method for each component, consider the influence of leakage flux between coils and armatures, establish the equivalent magnetic circuit model of a certain type of magnetic latching relay and get the static attractive force curve. Pick targets for the parameter design by matching the attraction and reaction forces. Use robustness as the parameter design method to optimize the critical parameter of the sample. Finally, proceed to SNR and parameter design and get the optimized parameters. The new parameters not only satisfy the standards of output characteristics but also greatly improve the qualified rate of key points in matching attraction and reaction forces.
