Abstract: A modularized control circuit of a fan motor is used to provide a phase-sensing control to the fan motor. The modularized control circuit includes a driving circuit and a microcontroller IC. The driving circuit is electrically connected to the fan motor to produce a plurality of analog driving voltage signals to drive the fan motor. The microcontroller IC is connected to the driving circuit and includes a phase-sensing module, a control unit, and a driving signal generator. The phase-sensing module receives the analog driving voltage signals to sense phases thereof and to produce a phase trigger signal. The control unit is connected to the phase-sensing module and receives a speed signal and the phase trigger signal to produce a control signal. The driving signal generator is connected to the control unit and receives the control signal to produce at least one switch driving signal to control the driving circuit.

Abstract: 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.

Abstract: A fan failure backup apparatus includes a first fan module and a second fan module. When a second control unit of the second fan module realizes that the first fan module is failed through a first control unit of the first fan module, and the second control unit realizes that the second fan module is not failed, the second control unit controls the second fan module to additionally enhance a pressure-flow characteristic of a second fan unit of the second fan module.

Abstract: A control system includes a motor, an interface circuit, a motor controller and a detection control circuit. The interface circuit receives and converts a pulse width modulation signal. The fan dissipates heat when the motor is operated in a forward rotation mode and eliminates dust when the motor is operated in a reverse rotation mode. The detection control circuit reads a duty cycle of the converted pulse width modulation signal in real time. When the motor is operated in the forward rotation mode, the detection control circuit drives the motor controller to control the rotation speed of the fan according to the duty cycle. If the duty cycle is lower than or equal to a first threshold value, the detection control circuit drives the motor controller to switch operation mode of the motor from the forward rotation mode to the reverse rotation mode.
