Abstract
The present disclosure relates to a motor driver and a method of driving a motor capable of driving a motor with optimum efficiency. The method of driving the brushless direct current (BLDC) motor may include an initial driving operation, a test operation of adjusting a turn-on time and a transition time in the test mode step by step, driving the BLDC motor by applying the adjusted turn-on time and the adjusted transition time, 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 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.
