Modularized control circuit with signal-capturing function for fan motor and controlling method
A modularized control circuit with a signal-capturing function for a fan motor is disclosed. The modularized control circuit includes a driven circuit and a microcontroller integrated circuit. The driven circuit is electrically connected to the fan motor to produce at least one analog driven voltage signal, thus driving the fan motor. The microcontroller integrated circuit is electrically connected to the driven circuit and includes a signal-capturing module, a control unit, and a driven signal generator. The signal-capturing module receives an external pulse signal to produce a cycle-capturing signal. The control unit is connected to the signal-capturing module and receives the cycle-capturing signal to produce a control signal. The driven signal generator is connected to the control unit to receive the control signal, thus producing a plurality of switch driven signals for controlling the driven circuit.
