Abstract: 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 so as to rotate the rotor, and a control unit configured to, when a target command value is received, change a predetermined reference start-up time point to a start-up time point corresponding to an electrical angle position of the rotor in correspondence with the target command value per rotation of the rotor and to control the inverter to supply the driving voltage at the start-up time point.
