A bearing system is constructed with a pair of magnetic bearings, each of which is composed of three electromagnets whose pole faces are in the shape of a cone in order to have also the function of a thrust bearing. The bearing system is symmetric in structure and supports a symmetric rotor in the horizontal direction. The magnet cores are made of solid steel for simplicity in manufacturing. An approximate decoupling control system is designed for the regulation of the rotor position. Frequency responses of the rotor displacement to an input added to the control signal are obtained and are compared with the numerical results to verify the usefulness of the method in designing a decoupling control system, and of the linearized model presented previously. The transient responses to impact are examined to show the interactions between the motions in a nonlinear range. The results also allow discussion on the influence of insufficient rigidity of the stator and the effects of interacting control.
