Abstract
A fan operating control system includes a magnetic sensor unit, a control unit, a rectifier unit and a coil unit. The control unit is electrically connected to the magnetic sensor unit and the rectifier unit; the rectifier unit is further electrically connected to a ground; and the coil unit is electrically connected to the control unit and the ground. The control unit detects any fan electric current flowing through the coil unit and generates a rotating speed signal accordingly. When no fan electric current is detected at the coil unit, the control unit stops generating the rotating speed signal. Therefore, it is able to avoid a whole fan system from making an error decision and outputting rotating speed signal continuously when there is not fan electric current flowing through the coil unit, and any abnormal condition that would adversely affect the fan service life can be avoided, too.
