A control circuit is electrically connected to at least one fan device. The fan device has a motor and generates a sensing signal. The control circuit receives a power-source signal and the sensing signal and includes a power converting unit, a control unit and a switch unit. The power converting unit receives the power-source signal and thus respectively outputs a first power-source signal and a second power-source signal according to the power-source signal. The control unit receives the first power-source signal and the sensing signal and thus generates a control signal according to the sensing signal. The switch unit receives the control signal and generates at least one switch signal according to the control signal. The fan device receives the second power-source signal and the switch signal and drives the motor according to the switch signal.

Fan system and motor control circuit

A control circuit of a motor includes at least two sensor chips and at least two winding sets. The sensor chips are electrically connected to each other, and each of the winding sets has a first winding and a second winding. The first end of the first windings and the first end of the second windings are electrically connected to each other, and the second end of the first windings and the second end of the second windings are electrically connected to the sensor chips correspondingly. In addition, a motor having the control circuit is also disclosed.
