Abstract: The mechanical characteristics of the electromagnetic relay includ the suction and the counter force, and the proper matching of the two characteristics is an important basis for determining the range and stability of the mechanical and electrical parameters of the electromagnetic relay. Introduction was made to the principle of clapper type relay, the structure and the parameters. Via analysis of the impacts of ac/dc and different magnetic potential on suction characteristics, this paper researched the matching of suction and counter-force characteristics in the process of relays actuation and releasing. The results show that via technical parameters adjustment, the key parameters could be controlled to make the suction and counter force characteristics matching better.
Key words: electromagnetic relay; suction counter-force; improved design; application
