Abstract
A motor driving apparatus and a method of driving the same are disclosed. The motor driving apparatus includes a motor, an inverter configured to drive the motor based on a switching signal, and a controller configured to output the switching signal when pulse width modulation control is performed, to stop the pulse width modulation control when a predetermined condition is satisfied, and to apply a zero-voltage vector pulse to the switching signal in a period in which execution of the pulse width modulation control is stopped, for determination of a current speed estimation value of the motor.
