This paper presents natural frequencies as a result of experimental model analysis of the whole system – motor, actuator system and steel frame foundation – and compares them to the numerical modal analyses using a finite element model. Additionally, forced vibrations are measured using the actuators as a shaker to de­ rive the resonance frequencies of the system. The measured natural frequencies by modal analysis, the measured resonance frequencies and the simulated natural fre­ quencies are compared to each other. Additionally, the necessary electrical power of the electrodynamic actuators is analysed. 12th International Conference on Vibrations in Rotating Machinery Proceedings of the 12th Virtual Conference on Vibrations in Rotating Machinery (VIRM), 14-15 October 2020 https://www.taylorfrancis.com/chapters/oa-edit/10.1201/9781003132639-27 9781003132639 12th Virtual Conference on Vibrations in Rotating Machinery - VIRM 12, 2020 Begutachtet/Reviewed publish false false Creative Commons - CC BY-NC-ND - Namensnennung - Nicht kommerziell - Keine Bearbeitungen 4.0 International Raimund Wachter Ulrich Werner Hans-Georg Herzog Christian Bauer eng uncontrolled Induction motors eng uncontrolled Actuator system eng uncontrolled Vibration analysis Institut für leistungselektronische Systeme ELSYS Energie & Ressourcen
