Relüktans türü ivmelendirici devre modeli için uygun bir Lagrange tanımı sunulmuştur. Magnetostatik sonlu eleman analizi yapan genel amaçlı programların, sunulan model üzerinde ne kadar etkin bir şekilde kullanılabileceği gösterilmiştir. Bir sistemin elektrik devre modeli, sistemi oluşturan parçaların davranışlarını, mekanik parçaların elektriksel eşdeğerleri de dahil olmak üzere akım, gerilim, güç ve enerji dağılımı gibi karşılıklarıyla kolay algılanabilir bir şekilde ortaya sermektedir. Bu tür tahrik sistemleri durağan çalışma şartlarında oldukça basit dinamiğe sahip olmakla birlikte geçiş durumlarında oldukça komplex davranış gösterirler ve çalışma dinamiklerinin anlaşılmaları güçtür. Çalışma, böyle bir yaklaşımın tam bir elektromanyetik alt yapıya sahip olmayan araştırmacılara doymuş veya doymamış relüktans tipi doğrusal veya dairesel hareket eden motor veya elektrikli tahrik sistemlerinin ve dinamik yapılarının daha iyi anlaşılabilmesi için yapılmıştır. Önerilen model ve dinamik davranışlarının sonlu eleman analizleri ile çözümü, bir relüktans ivmelendirici düzeneği gerçeklenip kondansatör boşaltmalı bir devre ile sürülerek doğrulanmıştır.

Lagrangian description of electrical circuit model of a reluctance type accelerator system is introduced. The effectiveness of the general purpose magnetostatic finite element analysis (FEA) tools on the introduced model is demonstrated. Electrical equivalent circuit model of the system lays out many properties of the system in terms of voltage, current, power or energy distributions of electrical components, and also electrical equivalent of the mechanical components, in an easily perceivable form. These type of actuators are simple mechanisms when they are in steady state. However, when they are in transient, their dynamics may become very complex. The aim of the study is to show how this approach allows many researchers without the full electromagnetic background, to model and understand the dynamics of the reluctance type linear or rotary motor or actuators whether they are saturated or not. To exhibit the validity of the proposed model and solution of dynamic behaviors with FEA, it is verified on a basic capacitor discharge type driver circuit including the electromagnetic accelerator coil and projectile.
