Abstract. This paper presents design of brushless DC (BLDC) motor which is applied in air fan module for fuel cell power pack. Developed motor is outer rotor type BLDC motor, high efficiency and low cost are main targets to achieve in design process. Manufactured motor is combined with blade fan, and air flow and pressure with respect to the various load conditions are measured. From the simulated and measured results, we verify the application possibility as air fan module for power pack.
