摘要： The direct current vibration motor comprises a stator, a rotor rotatably attached on this stator, and a cylindrical cover for sealing the rotor. The stator has four permanent magnets arranged in a ring-like configuration and magnetized in an axial direction. The rotor is provided with an armature eccentrically fixed to a portion in the circumferential direction of the rotation shaft. The armature comprises a first coil and a second coil. Furthermore, the armature is provided with a pin formed of a magnetic body for regulating the static position so that the first coil and the second coil are fixed at a position where the first coil and the second coil are deviated from the central position of the magnetic pole of the stator. Current is supplied to the coils with the commutator and the brushes arranged with the spatial phase angle of 90°.
