PURPOSE: A low voltage driven motor is provided to reduce a current consumption by elevating a plurality of iron pieces through the use of attractive and repulsive forces and driving a cam and a rotor through the use of the elevating force. CONSTITUTION: A low voltage driven motor comprises a frame(10); a magnetic unit(20) arranged in the frame; a rotor(30) shaft-coupled into the magnetic unit, and which has magnetic poles different in each of sections; a plurality of iron pieces(40) interposed between the magnetic unit and the rotor, and which are movable in a vertical direction by a magnetic force; a rotating unit connected to the ends of the iron pieces, and which rotates a cam unit(50) coupled to the outer surface of the shaft of the rotor; and an initial driving unit for driving the rotor for a predetermined time period when a current is supplied. The rotating unit includes support arms(45) connected to the ends of the iron pieces; connectors(48,49) for connecting the support arms; and slide bearings(47) arranged at the ends of the support arms, and mounted on the cam unit.
