A superconducting magnetic bearing can levitate a rotor without contact. However, the rotor can whirl with large amplitude. To reduce the whirling amplitude, we focused on an electromagnetic shunt damper that is appliable to a rotor system. In this paper, an analysis considering influence of magnetic flux density distribution on dynamics of the rotor was carried out. From linearized and nondimensionalized governing equations, we obtained one parameter that determines the damper's effectiveness. Further, numerical calculation was performed and the optimum value concerning the dimensions of the electromagnetic shunt damper was obtained.
