| Abstract |
A special signal processing method (order analysis) allows welldefinedconclusions from accelerometer measurements on electrical drivesregarding the reasons of structure-borne and airborne sound. In this paperan analysis of acceleration signals of an 5kW induction machine is presented.The special feature is that a projection of sound curves is included inthis analysis. Thus it is possible to assign an oscillation excitation to harmonicsattributed to the machine design or harmonics of the feeding frequencyconverter. |
