Claim 12:
13. The motor drive method of claim 12, wherein:
step B) is to generate the feedback determination signal by comparing the average voltage of the feedback signal with the first feedback voltage level that is between 0.2 volts and 0.35 volts, the second feedback voltage level that is between 0.7 volts and 1.0 volts, and the third feedback voltage level that is between 1.2 volts and 1.5 volts; and
step C) is to generate the modulated pulse signal that has the modulated duty cycle which is between 35% and 40% when receiving the first feedback determination signal from said feedback determination module, to generate the modulated pulse signal that has the modulated duty cycle which is between 50% and 60% when receiving the second feedback determination signal, and to generate the modulated pulse signal that has the modulated duty cycle which is between 65% and 75% when receiving the third feedback determination signal.
