A motor driving apparatus according to an embodiment of the present invention includes: a power supply unit which receives battery power or ignition power to supply power to a control unit; a gate driver which receives the battery power or ignition power to operate a switch of a motor driving unit; a control unit which receives power from the power supply unit and controls the gate driver; and a motor driving unit which receives battery power to drive the motor. The power supply unit and the gate driver receive ignition power when an abnormality occurs in the supply of battery power. Therefore, the motor driving apparatus can determine whether there is a failure in a situation in which the supply of battery power is cut off and can perform stable emergency braking.
