Original Abstract Submitted

a motor driving apparatus includes a motor an inverter driving the motor based on a switching signal, and a controller. the controller determines a current position estimated value of the motor by applying a zero-voltage vector pulse to the switching signal when entering the driving control of the motor, determines whether the motor is in a stop state according to an amount of change in the current position estimated value, and performs a pulse width modulation control by adjusting a duty ratio of the switching signal when the motor is determined to be in the stop state.
