Abstract
An experimental study was carried out to determine a practical minimum of the noise emission of an induction machine cooling construction. In order to do so the effects of design parameters on the noise emission and also the aerodynamic performance (responses) were measured in a test set up. The design parameters (factors) chosen for the study were tip-clearance, impeller axial positioning in the shroud and the distance between impeller and machine. The results are presented in the form of the specific sound power levels as a function of flow coefficient. The results indicate that the most import parameter affecting the specific sound power level is the tip clearance.
