Abstract: A motor control method adapted for use in the startup process of a sensorless brushless DC (BLDC) motor includes the following steps. A phase voltage signal and a driving voltage signal are generated according to the startup current signal with a first predetermined value and a phase current signal. A driving current signal is generated according to the driving voltage signal to drive the BLDC to rotate. The driving current signal is sensed to generate the corresponding phase current signal. The load state of the shaft end of the BLDC is determined according to the phase voltage signal with the change of the corresponding phase current signal and the startup current signal. The magnitude of the startup current signal is adaptively adjusted according to the load state of the shaft end and/or according to the electric rotation angular velocity and the torque demand of the BLDC motor.
