Abstract: The invention provides a monitor circuit, which is used for a fan and receives a driving current and a driving voltage of the fan. The monitor circuit includes sensing circuits and a microcontroller. The sensing circuits respectively sense statuses of the fan and output sensing values. The microcontroller is used for monitoring whether the sensing values exceed preset value ranges respectively to obtain comparison results. The microcontroller outputs warning signals according to the comparison results. Each of the warning signals has a specific frequency.

Abstract: An axial fan includes a fan frame, an impeller and a motor. The fan frame has a frame body, a base and plural connecting members. The base is disposed at the center of a side of the frame body. The connecting members connect the frame body to the base. The impeller is accommodated in the frame body and disposed on the base. The impeller has a rotating shaft, a hub and plural blades disposed around the hub. The motor is disposed on the base and connects with the rotating shaft to drive the impeller to rotate. When the impeller rotates forwardly, the airflow is induced to flow through the connecting members, blades, and one side of the frame body away from the base. When the impeller rotates reversely, the airflow is induced to flow through the side of the frame body, blades and connecting members.

Abstract: An anti-air-return fan system includes a motor, a driving control circuit, and a rotation judgment circuit. The driving control circuit is electrically connected to the motor. The driving control circuit has a driving signal for driving the motor to rotate according to the driving signal. The rotation judgment circuit outputs a judgment signal to the driving control circuit when detecting that the motor reversely rotate. The driving control circuit executes a braking according to the judgment signal. The driving control circuit drives the motor to operate when the rotation judgment circuit detects that the motor doesn't rotate reversely.
