![]() ![]() Users expect, that their machines are running safe and reliable and that they have a high efficiency and availability. In various technical areas rotating machinery systems are in operation, like turbines, pumps, compressors, motors, generators, etc. Furthermore, a state-space model of the entire mechatronic system is developed to facilitate the diagnosis procedure. The paper compares force measurement results and achievable accuracies of a radial magnetic bearing using different measurement techniques over a large operating range. For this type of diagnosis using transfer functions, an accurate force measurement is crucial. The identification and diagnosis procedures are based on frequency response functions. ![]() ![]() The aim of the presented projects of the Special Research Program (SFB 241) supported by the German Research Council (DFG) is to use active magnetic bearings as an identification and diagnosis tool for turbomachines. Therefore, the active magnetic bearings are well suited to operate contactless as actuator and sensor elements in rotating machinery. Their main advantages are the contactless working principle, the frictionless suspension, and that they represent an active system. Active magnetic bearings, a typical mechatronic product, have been successfully applied in industrial turbomachinery. ![]()
