PURPOSE: An electromotive driver is provided to prevent the overload of a motor by having a transformer within the electromotive driver. CONSTITUTION: An electromotive driver is composed of a power input unit(302), a switch control unit(304) for controlling the starting and rotary direction of a motor, a motor unit(306), a gear unit(308) for changing rotary speed and direction according to the rotary speed and direction of the motor unit, a tool unit(310) for rotating in a forward or reverse direction, and a transformer(300). The transformer transforms 220 AC voltages into 110 DC voltages.
