Abstract
Multiple magnetic suspension suspends multiple floators with a single power amplifier. It is classified into parallel magnetic suspension and series magnetic suspension. In this paper, the feasibility of parallel magnetic suspension is studied experimentally. Parallel magnetic suspension systems are classified into series-connected and parallel connected according to coil connection. This paper focuses on the current-controlled multiple suspension system with parallel connected coils. Stable levitation with two floaters is achieved by using PD control.
