The subject of this paper is an improvement of a selfsensing
control of a three-phase radial magnetic bearing based on
the so called INFORM method. The focus of this paper lies on a
modification of the space vector modulation to achieve a high
position resolution as well as a high actuator dynamic at low DClink
voltage levels. Therefore, certain constraints for the space
vector modulation must be fulfilled to allow a self-sensing
operation of the bearing. For this reason, different kinds of space
vector modulations are designed theoretically as well as proven in
experiments on a prototype of a radial magnetic bearing. Finally,
the obtained performance of the INFORM method is shown by a
linearity measurement and a comparison of the small signal
behavior by means of external position sensors.
