Investigating the Effect of Water Contamination on Gearbox Lubrication based on Motor Control Data from a Sensorless Drive

, 2014
Water is one of the most significant destructive contaminations to lubricants which in turn lead to more power consumption and early damage to rotating machines.

Fully position sensorless control of a magnetically levitated Reluctance Synchronous Machine by three phase active magnetic bearings

, 2015
This paper discusses a fully position senslorless controlled magnetically levitated drive. Sensorless means, that no external position sensors are used and the position is obtained from electrical quantities of the actuator itself.
