PURPOSE: A vibration motor is provided to improve the part reliability by replacing the rotator of resin material with a rotor substrate with improved thermal property. CONSTITUTION: A lower case(210) is installed with a brush(240) and a magnet(250). An upper case(290) is combined with the lower case to form the external housing. A rotor substrate(270) is installed to the supporting shaft of the upper case and the lower case in detachable way. The rotor substrate comprises a coil seating groove, an eccentric weight seating groove, and a boss. A bearing(260) revolves around the supporting shaft. |
