English abstract:
This paper presents results of a three phase radial active magnetic bearing architecture
combined with a sensorless position control algorithm. Therefore the three coil bearing
structure is utilized by a three phase voltage source drive inverter. To reduce bias current
consumption permanent magnet bias fluxing is used and iron losses are reduced by gaining
homopolar architecture. The sensorless position detection algorithm and the control
architecture are presented. Experimental results confirm the sensorless concept by
measurements and quality measures for the sensorless method are investigated to show the
limits of operation.
