Reduction of Foundation Vibrations Caused by Pulsating Air Gap Torques of Converter-Driven Induction Motors Using an Active Vibration Control System (AVCS)
- The paper focuses on a specific kind of excitation caused by pulsating air gap torques in converter-driven induction motors. It presents a theoretical analysis of a converter driven induction motor based on a simplified 3D model, where three active actuator systems and one passive actuator system are positioned between motor feet and an elastic steel frame foundation and where the vertical motor feet vibrations at the active actuator systems are fed back to separate controllers, representing an active vibration control system (AVCS). Based on this model, the mathematical coherences are presented as well as a numerical example of a converter driven induction motor, where the foundation vibrations due to pulsating air gap torques are analysed. The paper demonstrates that, also for this kind of excitation, the vibrations can be significantly reduced by the AVCS compared to an induction motor mounted directly on a steel frame foundation.
