Resumo

An induction-type linear-pulse electromechanical converter with an external magnetic, electromagnetic, or combined magnetic–electromagnetic shield has been considered. A mathematical model of a converter, which takes into account rapid interconnected electromagnetic, thermal, and mechanical processes, has been developed using the finite-element method. The effect of the geometrical parameters of a shield on the converter performance has been considered. A criterion of efficiency that takes into account the relative values of the efficiency, mass, and stray field of a converter has been introduced. It has been shown that the efficiency of a converter with a combined shield is two to three times higher than that when using a magnetic or electromagnetic shield of the same dimensions.
