| Abstract |
The traditional approach for the prediction of noise radiated from induction motors is usually based on 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 almost impossible to make. In this paper, a statistical method especially suited for calculations at high frequencies is introduced. Results demonstrate the feasibility of the method and particularly its ability to discem the contribution of various components of a motor to the overall radiated noise. |
