Abstract

The non-symmetrical twelve poles active magnetic bearing (AMB12) actuator has been considered. We also included the control system for the computer simulation. We have used the field-circuit method modeling included under various speed of the rotor. The electromechanical equation system has been solved taking into account the integral parameters obtained from Finite Element Method (FEM) analysis of the magnetic field. We verified the calculations by the measurement tests under various values of the rotational speed of the AMB rotor. A good agreement has been achieved.
