Abstract

The intensity of the exciting force of rotating systems supported by active magnetic bearings is limited by the maximum load capacity of the bearings. Also, the maximum electrical current of control is limited by the saturation current of the ferromagnetic material of the bearing. The force and electrical current of control depend on the transfer function of the control circuit, which can vary as a function of the fitted parameters for the controller, normally a PID controller. At the design stage it is very important to carry out an analysis of these parameters. Therefore in this work a theoretical procedure to determine the force and control current of active magnetic bearing is presented. The theoretical results will be compared with experimental data to verify the accuracy of the procedure.
