Patent

CA 2340957

A DC brushless vibration motor is disclosed to comprise of a stator, a rotor, a drive circuit and a casing. The stator has an upper magnetic pole piece, a lower magnetic pole piece and a stator field winding. The stator field winding is contained inside a ring-shaped space formed by the upper and lower magnetic pole pieces. The internal rotor has a center of mass offset from the center axis of rotation and comprises a ring magnet and an eccentric weight. The eccentric weight has a structural configuration of a ring body, and the ring magnet is securely fixed to the external peripheral surface of the eccentric weight. The drive circuit has a drive integrated circuit for controlling the rotation of the rotor by receiving an externally- supplied electric power. The casing securely encloses the stator and rotor while maintaining an air gap therebetween for generating mechanical vibration when the rotor is propelled to rotate by the stator.
