Fan system and detector thereof
First Claim
1. A fan system, comprisinga motor;
- a driving unit, electrically connected to the motor, for generating a driving signal to drive the motor and generating a detection signal; and
a detector, electrically connected to an output terminal of the driving unit, for receiving a voltage signal and the detection signal;
wherein when the motor operates normally, the detector outputs an examined signal to the output terminal of the driving unit; and
wherein when the motor operates abnormally, the driving unit asserts the detection signal, and the detector is controlled by the asserted detection signal to transform the examined signal to an alarm signal according to the voltage signal.

Abstract
A fan system including a motor, a driving unit, and a detector is disclosed. The driving unit is electrically connected to the motor and generates a driving signal to drive the motor and a detection signal. The detector is electrically connected to an output terminal of the driving unit and receives a voltage signal and the detection signal. When the motor operates normally, the detector outputs an examined signal to the output terminal of the driving unit. When the motor operates abnormally, the driving unit asserts the detection signal, and the detector is controlled by the asserted detection signal to transform the examined signal to an alarm signal according to the voltage signal to detect the abnormal state.
