ABSTRACT:
A control device for driving a motor which includes a rotor and a stator is provided. The control device includes a Hall detector and driving circuit. The Hall detector detects magnetic flux variation when the rotor rotates and generates a first detection signal and a second detection signal. The first and second detection signals represent current rotation location when the rotor rotates. The driving circuit generates a driving signal to drive the stator. The driving circuit turns on or off the driving signal according to a control signal and the relationship between the first and second detection signals.
