A Theoretical and Experimental Investigation of the Magnetic Fields and Forces Arising in Magnetic Suspension Systems.
Abstract
Analytical and experimental studies have been performed to obtain the fundamental relationships governing the transverse forces between an axially active, transversely passive electro-magnetic supporting system. The basic criteria have been obtained for a plane geometry. Approximate solutions have been obtained with the use of some simplifying assumptions regarding the boundary conditions which permitted relatively straightforward solutions to be obtained through the use of conformal mapping with Schwarz-Christoffel transformations. A static experimental apparatus has been developed for measuring axial and tangential forces and fluxes in the gap between the magnetic surfaces. Good agreement between theory and experiment has been obtained. The theory indicates the existence of optimum geometric configurations which can provide maximum degree of stiffness and tangential force for a given surface area and provides the criteria for determination of these configurations.
