PURPOSE: A flat coreless vibrator motor is provided to obtain high quality vibration by using a coreless motor mechanically comprising two coils and three conductors, thereby making resistances of each phase uniform CONSTITUTION: A stator includes a flat magnet in which N and S magnetic poles are alternately formed. A rotor is supported so that it is freely rotated by using the magnet having an interval between the magnet and the rotor. The rotor comprises a plurality of coreless armature coils and a rectifier connected to the coils. A brush supplies a current to the coils through the rectifier of the rotor. Two coils of the armature coils of the rotor are overlaid at a same position, and are integrally formed. The sizes of the tow coils is larger than the other coils of the armature coils of the rotor.
