Abstract :
A special signal processing method (order analysis) allows well-defined conclusions from accelerometer measurements on electrical drives regarding the reasons of structure-borne and airborne sound. In this paper an analysis of acceleration signals of an 5 kW induction machine is presented. The special feature is that a projection of sound curves is included in this analysis. Thus it is possible to assign an oscillation excitation to harmonics attributed to the machine design or harmonics of the feeding frequency converter
