Modelling of Non-laminated magnetic bearings

Abstract

Eddy currents are generated in a nonlaminated geometry axial magnetic bearing actuator by a time-varying magnetic field. Therefore, it has a great influence on the dynamics and control design of nonlaminated electromagnetic suspension systems. this paper, the approximate formula of effective air element reluctance is given close to the original formula, there by providing a more accurate mathematical model. In particular, the author has provided a nonlinear dynamical model on the time domain of the nonlaminated geometry magnetic bearing.
