Abstract

<p> We developed a permanent magnet (PM) repulsive type magnetic levitation (maglev) system that supports a ring permanent magnet with extremely low magnetic stiffness in a noncontact manner. In this system, the ring permanent magnet is supported with a stiffness of only 19.6 N/m in the levitation direction. A sensor assembled with four Hall-ICs linearly detects a change in magnetic field associated with the motion of a levitated ring PM, and four air core coils control the magnetic field distribution in the space around the PM. These components actively stabilize the horizontal translational motion of the levitated ring PM. Our aim is to apply this device to micro mass measuring instruments and high sensitive vibrometers.</p>
