  • DC fan having a power sleep-mode control unit and method for controlling the same
    Patent number: 6321029
    Abstract: A DC fan using a power supply and sleep/non-sleep-mode signals for controlling the rotating speed thereof includes a DC brushless motor and a power sleep-mode control unit. The DC brushless motor serves as a driving source of the DC fan. The power sleep-mode control unit is electrically connected to the DC brushless motor for receiving the power supply and the sleep/non-sleep-mode signals, thereby outputting an operating power supply and controlling the rotating speed of the DC brushless motor.
