PURPOSE: A driving device for a cooling fan of an outdoor unit of an air conditioner and a cooling fan using the same are provided to join a motor and impeller on a same rotary shaft without increasing the number of components and to minimize vibration at the same time with transferring a torque of a motor by using a dust absorption member. CONSTITUTION: A driving device for a cooling fan of an outdoor unit of an air conditioner comprises a rotary shaft(40), a motor(1), a stator support unit(10), a support bracket(20), and first and second bearings. An impeller(51) is supported in a front end portion of the rotary shaft. The motor comprises a rotor(80) in which the rotary shaft is joined to the central part and a stator(30) for rotating the rotor. The stator supporting unit is formed into a reversed cup shape and the stator of the motor is supported in the outer circumference of the stator support unit. The support bracket is formed into a cup shape and the upper part of the stator is joined to the lower part of the stator support unit. The outer circumference of the support bracket is supported to a frame of an outdoor unit of an air conditioner. The first and second bearings are respectively installed in the inner circumferences of the stator support unit and support bracket, thereby supporting the rotary shaft to be rotated. |
