MOTOR DRIVING APPARATUS AND MOTOR DRIVING METHOD

摘要

There are provided a motor driving apparatus and a motor driving method capable of decreasing power consumption by readjusting a preset duty ratio according to a voltage level of driving power. The motor driving apparatus includes: a driving power detecting unit detecting a voltage level of driving power used to drive a motor; a speed controlling unit adjusting a preset duty ratio of a pulse width modulation (PWM) signal when the voltage level detected by the driving power detecting unit is equal to or less than a preset reference voltage; a driving controlling unit generating a driving signal having the duty ratio from the speed controlling unit; and a driving unit driving the motor according to the driving signal of the driving controlling unit.
