Abstract: A driving circuit drives a motor containing a first coil and a second coil. The driving circuit includes a switching unit, an operation unit and a control unit. The switching unit receives a switching signal from the control unit for driving the motor. The control unit detects the rotation speed of the motor. When the rotation speed of the motor is greater than a predetermined rotation speed, the control unit outputs a first operation signal to the operation unit to couple the first terminals of the first and second coils and couple the second terminals of the first and second coils. When the rotation speed of the motor is less than or equal to the predetermined rotational speed, the control unit outputs a second operation signal to the operation unit to couple the second terminal of the first coil to the first terminal of the second coil.

Abstract: A method for controlling a fan in a fan start-up stage including a first time period and a second time period comprises the following steps of: during the first time period, continuously providing a first driving signal to drive the fan; and during the second time period, continuously providing a second driving signal to drive the fan; wherein, the signal value of the first driving signal gradually decreases until being equal to the signal value of the second driving signal. Wherein the signal value of the first driving signal non-linearly decreases, the signal value of the second driving signal is an unchanged value. Wherein, the first time period and the second time period are adjusted for a different fan but the sum of the first time period and the second time period is always the same. A fan is also disclosed.

Abstract: A single phase brushless DC motor comprises a Hall effect sensor, a coil assembly and a motor control circuit which generating a driving signal to guide a coil current flowing through the coil assembly. The Hall effect sensor senses the magnetic pole of the rotor to accordingly generate a Hall effect signal. The motor control circuit outputs a current polarity reverse signal according to the voltage at one end of the coil assembly. The time when the current polarity reverse signal is generated corresponds to the polarity reverse time of the coil current. The motor control circuit adjusts the phase of the driving signal according to the polarity reverse time of the Hall effect signal and the time when the current polarity reverse signal is generated to synchronize the phase of the back emf of the single phase brushless DC motor with the phase of the coil current.
