Analysis of active vibration reduction for soft mounted electrical machines based on a multibody model

  • The aim of the paper is to analyze active vibration reduction of soft mounted electrical machines by using actuators between the motor feet and a soft foundation based on a multibody model. The actuator forces are inserted directly in the vibration model without using a feedback control system. The goal is to reduce the forced vibrations, which are caused by typical excitations of electrical motors — eccentricity of rotor mass, bent rotor deflection and magnetic eccentricity. Based on the simplified model, the mathematical coherences are derived and a numerical example is shown, where different vibration reduction concepts are analyzed and the necessary actuator forces are calculated. The aim of the paper is to show the capability of using actuators between motor feet and soft foundation, based on a simplified multibody vibration model. For future work, the multibody model has to be implemented into a feedback control system for active vibration control.
