Characteristics Analysis of Magnetic Suspension Mechanism with Variable Flux Path Control
This paper proposes a magnetic suspension system using a disk-type permanent magnet and a rotary actuator. In this suspension system, the suspension force is controlled by a variable magnetic flux path mechanism where the flux path is changed by varying the angle of the magnet. This system has the characteristics of semi-zero suspension force, variable magnetic poles, and energy-saving suspension. In this paper, the variable flux path control method and an experimental prototype are introduced. Based on the results of the basic experiments, numerical simulation, and suspension experiments, the characteristics of the proposed mechanism are analyzed.
