Numerical And Experimental Aspects Concerning The Static and Dynamic Regime Of A Linear Actuator

Constantin Stoica, Dumitru Cazacu, Ion Catalin, Leonard Melcescu


In this paper the dynamic behavior of a D.C. linear actuator is analyzed. A finite element numerical model was used. A coupled system of electrical and mechanical differential equations was solved by coupled simulation among magnetic field transitory regime, electric circuit and mechanical translation with variable speed. The time variations of the current, of the magnetic force and of the moving part speed were determined. The current variation was validated by experimental measurements.
