Abstract
The prediction and analysis of the audible noise of inverter supplied squirrel cage induction motors is an electromagnetic problem. The calculation requires the input from the current and voltage spectrum of the inverter used to supply the variable frequency to the motor. However, the electromagnetic design of the motor as such has to be taken into account. Given the electrical input and the motor electromagnetic data, the forces exciting the mechanical structure can be determined. In order to find out whether or not a high audible noise level has to be expected, the mechanical response, either theoretical or experimental has to be obtained. This section discusses the various steps in the analysis and their mutual interactions. In addition several examples are given illustrating the approach.
