  • Fan control system using a microcontroller
    Patent number: 6779981
    Abstract: A fan control system. The fan motor is operated normally at not greater than a preset maximum rotation speed. The fan control system has a programmable microcontroller to receive an input voltage and a rotation speed signal corresponding to the actual rotation speed of the fan motor, determining an output signal according to the input voltage and the rotation speed signal, and outputting the output signal; and a fan-driving unit to receive the output signal and adjusting the rotation speed for driving the fan motor according to the output signal. When the rotation speed is lower than a predetermined rotation speed, the rotation speed is in a relation of a first function to the input voltage; when the rotation speed is greater than the predetermined rotation speed, the rotation speed is in a relation of a second function to the input voltage.

    Abstract: A fan control system. The fan motor is operated normally at not greater than a preset maximum rotation speed. The fan control system has a programmable microcontroller to receive an input voltage and a rotation speed signal obtained by detecting the actual rotation speed of the fan motor, determining an output signal according to the input voltage and the rotation speed signal, and outputting the output signal; and a fan-driving unit to receive the output signal and adjusting the rotation speed for driving the fan motor according to the output signal.
