The electromagnetic dynamics is analyzed by calculating the total reluctance of the magnetic equivalent circuit (MEC), which is composed of a fixed length iron core and an angular air gap. Magnetic saturation and angular dependency of the reluctance are considered in the analysis. Then, an energy balance over the electromagnetic components of the system is used to obtain the torque which drives the movable armature. A planar mechanism of four rigid bodies, including spring-damping torques that restrict the motion and model the contact bounces that occur in the switchings, is proposed to explain the dynamics of the movable components. Experimental tests show the accuracy of the model in both the electromagnetic and the mechanical parts. info:eu-repo/grantAgreement/ES/MEC/FPU14-04171 info:eu-repo/grantAgreement/ES/MINECO/IPT2011-1158-920000 info:eu-repo/grantAgreement/ES/MINECO/RTC-2014-1847-6 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.937 2016 ENGINEERING, MULTIDISCIPLINARY 13 / 85 = 0.153 2016 Q1 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 63 / 260 = 0.242 2016 Q1 T1 0.962 2016 Control and Systems Engineering 2016 Q1 Industrial and Manufacturing Engineering 2016 Q1 Electrical and Electronic Engineering 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-3032-954X Sagues, Carlos Universidad de Zaragoza (orcid)0000-0003-4609-1254 Llorente, Sergio 5007 520 Universidad de Zaragoza Dpto.
