Abstract:
The present invention provides a brushless vibration motor. A bracket has a burring part protruding upwards. A shaft is fitted at a first end thereof into the burring part. A stator comprises at least one coil which is provided on the upper surface of the bracket. The bearing is rotatably fitted over the circumferential outer surface of the shaft. The rotor has a rotor yoke fitted over the circumferential outer surface of the bearing, a magnet coupled to the rotor yoke, and a weight causing eccentric rotation. The stopper is provided on a second end of the shaft and is spaced apart from the upper end of the bearing to by a predetermined distance. The brushless vibration motor of the present invention has no a separate casing, thus enhancing spatial utilization.
