PURPOSE: A motor control apparatus is provided to reduce parts count and manufacturing costs by eliminating the need of using a brake power supply for supplying braking power for braking a motor. CONSTITUTION: A motor control apparatus comprises a braking power generating unit(30) for receiving a power having a voltage level smaller than the voltage level of a braking power, boosting the received power, and outputting the boosted power as the braking power; a switching element(40) which is electrified so as to permit the braking power generating unit to store the input power, and opened in such a manner that the braking power generating unit boosts the input power and the stored power and outputs the boosted power as the braking power; a control unit for controlling operation of the switching element; and a controller power supply unit(60) for supplying the power for operating the control unit to the control unit.
