Abstract
An experimental investigation was carried out in order to find out a practical optimum for an induction machine cooling fan construction. The main task was to detect the most influential design parameters on the noise characteristics and also the aerodynamic performance of the experimental set up. Due to a large amount of parameters and individual tests, the introduction of a method known as Design of Experiments (DOE) was carried out. Three structural factors were chosen to vary in the experiments. These factors were tip-clearance, impeller axial positioning inside the inlet shroud and the distance between the impeller and motor. The specific sound power level of the fan set up was regarded as the most interesting response in the DOE method, but also the effects on both the flow coefficient and pressure coefficient were investigated. The DOE method has a benefit of being able to create a prediction model of the effects of the chosen factors on responses.
