Considerations on the Mechanical Dynamics of Interconnected Flux Three-Pole Magnetic Bearings

This work presents a step-by-step procedure on how to get the reluctance forces in the optimal three-pole magnetic bearing. These forces are analyzed near the equilibrium point, where linearization produces satisfactory results. Besides that, a linear dynamical system is proposed based on the operation under four types of disturbances, shaft with constant angular speed and small displacements over the center.
