Abstract: Disclosed is a brushless DC vibration motor. An eccentric weight of a rotor is securely sandwiched between a back yoke and a permanent magnet, being heavier to provide an increased vibrational force. A bearing coupling portion with upper and lower stopping protrusions prevents detachment of a bearing. A bracket is formed with grooves, instead of through holes, to strongly support a cogging plate of which pieces are connected with each other to form a single body for easy-placement on the bracket. An optimized area of the cogging plate can suppress the rotor not to rise during starting of the motor, resulting in no frictional noise, and a high stopping speed and uniform horizontal level of the rotating rotor.

Abstract: A BLDC vibrational motor is provided, which is improved so as to generate a larger vibrational force per same volume compared to prior arts. A cylindrical bearing is fixed to a doughnut-shaped permanent magnet directly so that the magnet can be disposed as close as possible to the center of rotation, and thus coils can have a reduced volume and be disposed as close as possible to the center of rotation. The external space of the coils can be secured larger as much as the movement of position of the coils, and the weight takes up the space for rotation, so that volume of the weight can be enlarged. Thus, the weight can be extended and disposed to the external space of the coils, it is possible for a vibration motor with a small volume to generate a large vibrational force, which facilitates slim designs of the vibrational motor.
