ABSTRACT:
Disclosed is an improved flat vibration motor to be disposed in a mobile communication terminal, etc. for generating a vibration signal. A brushless-type vibration motor without brushes and a commutator is adopted, instead of a brush-type vibration motor with the brushes and commutator. An eccentric portion is disposed on one side of the peripheral surface of a rotor made of a permanent magnet, and one or more pairs of hall sensors are mounted in the vibration motor so as to start and drive the vibration motor. A motor controller may be used as internally or externally disposed on the vibration motor. The arrangement of a stator coil is improved so as to reduce the loss of magnetic flux as well as remove the non-operation points, thereby preventing the starting and driving disorders of the vibration motor, and improving its performance and efficiency.
