This electromechanical damping device consists of an electrical system coupled magnetically to a mechanical structure under a nonideal excitation. An analysis of the effects of the parameters of coupling and of nonlinear coefficients with increasing of constant torque of the DC motor is presented.01-11engNonideal systemElectromechanical systemSommerfeld effectDamping deviceArtigo10.1007/s11071-008-9340-8WOS:000262088500001Acesso restrito
