Design of an electromagnetic regenerative shock absorber is proposed in this paper. In order to udincrease the efficiency of land vehicles the sources of energy losses have to be eliminated, or reduced. For this udreason, several systems, recovering kinetic energy and converting it into electrical power, were studied and uddesigned in the last years. This energy, converted into heat in traditional systems, is recovered to increase the udautonomy of the vehicle. The proposed device is constituted by a stator part which coils are placed in an udinnovative disposition. The moving part is constituted by a rod made in stainless steel with alternatedudpermanent magnets and spacers, so that the relative motion generates a great variation of the concatenated udmagnetic flux on the coils. A damper mathematical model is implementedin order to characterize the device udoperating. Several finite element analyses, conducted in ANSYS Workbench Magnetostatic, have confirmed udthe magnetic field and flux values obtained through the theoretical analysis.
