A fluid generating device and an electric apparatus utilizing the fluid generating device are provided. The fluid generating device includes a motor and an impeller driven by the motor. The motor is a single phase direct current brushless motor which includes a stator and a rotor. The stator includes a stator core and a stator winding. The stator core includes an outer ring portion, teeth extending inwardly from the outer ring portion, a pole shoe formed at the tooth. Slot openings are formed between the pole shoes. The rotor is received in a receiving chamber defined by the pole shoes. Inner surfaces of the pole shoes and the rotor form therebetween a substantially even air gap. The presence of even air gap can reduce the cogging torque of the motor, thus reducing the startup current and noise of the motor.
