Abstract

This paper presents an analysis of a magnetic suspension device which is used in place of mechanical bearings for the gyro rotors of inertial guidance systems. A formula for the suspension device's strength is derived, the criteria for the device's stability is given, and the device's potential instability (when that criteria is violated) is explained. Data are given of an experiment which confirms the analysis of this instability.
