A Multi-objective Design Optimization of a Centrifugal Cooling Fan on a TEFC Motor
A design optimization method of a centrifugal fan on a totally-enclosed fan-cooled (TEFC) motor was studied in this paper.A multi-objective optimization problem was formulated which is to decrease noise level of fan and to increase air flow rate at the same time.Two design variables,namely fan diameter (D) and blade height (H),were investigated.Responses surface models were established based on design of experiments to identify the mathematical relationships between fan performances and the design parameters.These models were later used in optimization.As a result,a Pareto front was obtained which illustrated the optimal trade-offs that can be achieved in design.The Pareto front was then experimentally verified on an in-house test rig by using acoustic holography techniques.
