PURPOSE: A structure of an alternating current servo motor driver is provided to reduce size and weight of the driver by integrating a detection circuit, protection circuit and a driver circuit into a single module. CONSTITUTION: A structure comprises a switching board(10) for outputting three-phase alternating current motor power signals to an alternating current servo motor in accordance with the input driving signal; a high density bus(20) capable of supplying a single high power, and which removes noises from the input pulse width modulation signal; and a PWM control board(30) mounted with a VLSI micro chip, and which controls the alternating current servo motor to operate in a stable manner by detecting the state of the current during the operation of the alternating current servo motor and correcting the output. The switching board, high density bus and the PWM control board are sequentially stacked in the space formed by a base plate and a cover(C).
