Summary:PURPOSE: A three-phase motor control device is provided to reduce the size and manufacturing costs for a servo motor system by reducing circuit elements, and improve the response speed of a three-phase motor with respect to a control signal. CONSTITUTION: A three-phase motor control device comprises a power supply unit(30) and a control unit(40). The power supply unit supplies driving power of a brake(10) and power of an inverter(20) at the same time, in accordance with a predetermined synchronization signal(50). The control unit outputs an inverter control signal for controlling the inverter and a power control signal for permitting the power supply unit to supply power to the brake and the inverter.
