Abstract

A diamagnetically stabilized levitating rotor demonstrates feasibility of creating small a low friction and low maintenance generator. The planar rotor described in this paper uses a triangular configuration of magnets that generate EMF by passing over coils placed below the rotor. Equations were developed to predict the generated EMF from a series of arc segmented coils. Additionally, this paper provides a method for estimating optimal coil size and position for this planar rotor. Experiments demonstrated that the EMF generated in the coils matches well with the predicted wave forms for each case and the optimization theory is close enough to be useful for design.
