Magnetic Suspension System

This paper proposes an improvement method of zero suspension force performance using a special permanent magnet for a magnetic suspension device. The zero suspension force of a permanent magnetic suspension device is indispensable for floating off when the suspended object is stuck on accidentally. Generally, the magnetic suspension system using permanent magnet is difficult to realize the zero suspension force, since the permanent magnet cannot make its attractive force zero. However, the proposed magnetic suspension device has realized the semi-zero power suspension and semi-zero suspension force, which mainly consists of a disk-shape permanent magnet, two “F” shape iron cores, a suspended object, and an actuator. In the magnetic suspension device, since there is magnetic leakage, the suspension force could not be made exact zero. Therefore, in this paper, the zero suspension force will be improved using a special shape permanent magnet. The comparison results indicate that the zero suspension force is decreased about 80 percent.
