Abstract :
The traditional approach for the prediction of noise radiated from induction motors is usually based on the finite-element and/or boundary-element methods. While these methods have been shown to provide reasonable estimates of the radiated noise at low frequencies (usually well below 2 kHz) and for small motors, the demands on computing memory and time render calculations at high frequencies and for large motors impractical to make as part of the design process. The statistical energy analysis technique, which is especially suited for calculations at high frequencies, has been applied to predict the acoustic noise of electromagnetic origin. Results demonstrate the feasibility of the method and its ability to discern the contribution of various components of a motor to the overall radiated noise.
