Abstract
This paper analyzes some basic design aspects for a three phase diamagnetic levitating rotor. A proposed design uses a triangular configuration of magnets for a levitating rotor. A formula for finding a the approximate levitation point of the rotor is given. The proposed system uses three phase alternating current and a nine coil configuration to drive the levitating rotor. For this configuration, moment plots for different radial positions and tilt angles of the coils are given for a specific coil geometry. In addition, a way to find the effectiveness of finitely thick diamagnetic plates by using the method of images is also presented with normalized plots for some common, cylindrical NdFeB magnet geometries.
