Sensorless start-up method for driving a brushless DC motor

At first, a plurality of detection modes are applied in sequence to a brushless DC motor, such that with respect to each of the detection modes a composite magnetic field generated by a motor current flowing through motor coils points in a different direction. Then, each of peak values of the motor...
