Realization of Parallel-Connected Double Magnetic Suspension

A double magnetic suspension system with parallel-connected coils is actualized in this work. The double magnetic suspension system includes a pair of subsystems, each of them has an electromagnet and a floator, and controls them by a single power amplifier solely. Double suspension systems are classified into two types based on the connection of the double coils: series connection and parallel connection. The feasibility of double magnetic suspension with series-connected coils has been already demonstrated in the previous works. This work focuses on double magnetic suspension with parallel-connected coils. The conditions for the system to be controllable are presented for its mathematical model. The feasibility of double magnetic suspension is demonstrated experimentally.
