PURPOSE: A flat type vibration motor is provided to increase a ratio of flux linkage and the torque by changing each position of a brush and a stator magnet to prevent the interference between the brush and the stator magnet. CONSTITUTION: A flat type vibration motor is eccentrically rotated by the electromagnetic force according to flux linkage between a stator magnet(203) and a rotator coil(204). A brush(208) and the stator magnet(203) are installed at both sides of the rotator coil(204). The brush(208) is opposite to the stator magnet(203) in order to prevent the interference between the brush(208) and the stator magnet(203). The stator magnet(203) is installed at an upper case(201). The rotator coil(204) is opposite to the stator magnet(203) installed at the upper case(201). The brush(208) is installed at a lower case(202).
