Disclosed herein is a motor driving apparatus including a motor including a stator and a rotor rotating in the stator, an inverter configured to supply a driving voltage to a stator coil wound on the stator or to cut off the driving voltage supplied to the stator coil, and a control unit configured to, when a target command value is received, set a start-up period for supplying the driving voltage per rotation of the rotor, according to an electrical angle position of the rotor estimated based on at least one of a voltage, current and counter electromotive force detected in the stator coil and the target command value, and to control the inverter to supply the driving voltage in the start-up period.
