Electromechanical model of an electric bell

Abstract

This article deals with electromechanical modeling of an electric bell. The actuator of the system is an electromagnet that excites a flexible hammer structure. The operation of the structure with the current and displacement variables is described by three systems of equations. The first one describes an electromechanical one, the second one describes the free movement of the hammer, and the third one is writing the elastic collision of the hammer with a bell. Based on the equations, a simulation program was developed under Scilab system, the displacement of the hammer and the current are illustrated by curves.
