Vibration isolation system using zero-power magnetic suspension is modified. A suspension spring is introduced in parallel with a series connection of a zero-power-controlled magnetic suspension and a normal spring that were used in the previous works. It can reduce the lord force that the zero-power magnetic suspension has to bear. A basic configuration of the modified vibration isolation system is shown. An analytical study demonstrates that the modified system maintains infinite stiffness against direct disturbance even if such spring is added.
