Optimum Design of Cooling Fan considering Experimental Method for Three-Phase Induction Motor

In this paper, the optimum design method of the cooling fan for the industrial 7.5kW class induction motor is presented. The shape of the cooling fan was made with a 3D printer through the experimental design method. The manufactured cooling fan was optimally designed using test and statistical methods. The optimum design result of cooling fan is validated through IEC60034-2-1.
