Abstract: Disclosed is a flat coreless vibrator motor for supporting a vibration calling mode in a mobile communication device. The invention provides a flat coreless vibrator motor capable of preventing the formation of an idle point, thereby obtaining a high average torque, and thus, a high efficiency, while providing a sufficient redundant space for installing a weight for an increased centrifugal force. The flat coreless vibrator motor comprises a stator including a flat field magnet having a plurality of alternate N and S magnetic poles, a rotor spaced apart from the field magnet by a predetermined distance to rotate freely, and a brush for supplying a current to the coils via the commutator of the rotor. The rotor includes at least three coreless armature coils and a commutator connected to the coils, and at least two of the armature coils are integrally formed together at a same position to form a non-coil section in the rotor.
