Stiffness Analysis of Magnetic Bearing : Radial Stable Stiffness of Radial Stable Type Magnetic Bearing

抄録

Radial stable stiffness of radial stable type magnetic bearing having more than one ring-shaped magnetic pole-piece has been analyzed by using the Schwarz-Christoffel transformation, and the results of calculations of stable stiffness have been indicated with the tooth-width, tooth-length, and groove-width used as nondimensional geometrical parameters, to examine the influence of each parameter. The influences of these geometrical parameters have been proved to be larger in the order of the groove-width, tooth-length and tooth-width.
