ABSTRACT:
Disclosed is a flat type vibration motor, in which a shaft is supported between a housing and a bracket. A rotor includes an upper board, A and B phase winding coils, an eccentric weight and a rectifier. The rectifier has a plurality of segments electrically connected to first and second ends of the A and B phase winding coils. A stator includes a lower board, a magnet and a pair of brush fingers electrically connected to a power supply and in contact with the segments. A pattern coil on the upper board electrically connects between a segment connected to a first end of the A phase winding coil and another segment connected to a second end of the B phase winding coil to generate electromagnetic force for rotating the rotor from an electrically disconnected section to an electrically connected section.
