Exact Analytical Method for Active Magnetic Bearings With Rotor Eccentricity

This article presents an exact analytical method for active magnetic bearings to obtain the magnetic field distribution with rotor eccentricity. Based on the subdomain method and the perturbation method, the active magnetic bearing is divided into two regions: the air gap and stator slots. Meanwhile...
