| Abstract: | Based on the analysis of the induced electromotive force and the electromagnetic coil dynamic impedance of electromagnetic coil under different working conditions,the expression for induced current because of excitation current and dynamic gap was obtained,and its reasonableness was also analyzed.By using the dynamic relationship to the electromagnetic support device,the expression for its additional support stiffness parameters and additional damping parameters was obtained under different working conditions.Then the phenomenon of additional damping parameters in the parameter identification experiment of the magnetic support device was expelained reasonably. |
| Keywords: | electromagnetic coil dynamic electromagnetic relations induced current electromagnetic support device |
