Claim 7:
8. A method of driving a brushless direct current (BLDC) motor, comprising:
an initial driving operation of driving the BLDC motor in a basic driving mode in a test mode;
a test operation of adjusting a turn-on time and a transition time in the test mode step by step, applying the adjusted turn-on time and the adjusted transition time to drive the BLDC motor, and detecting a driving error of the BLDC motor;
an operation of repeating the test operation when the driving error is not detected in the test operation; and
an operation, when the driving error is detected in the test operation, of setting the turn-on time and the transition time, which are adjusted in an operation just before the driving error is detected, as a turn-on time and a transition time in an optimum driving mode.
