The present invention relates to a disk type vibration motor of a cellular phone, and in particular to a disk type vibration motor which adapts two phase direct current motor. The disk type two phase vibration motor according to the present invention includes circular upper and lower covers, a stator fixed to the lower cover and formed of two permanent magnets which divide a circular ring into two parts, the brushes fixed to the lower cover in the inner side of the circular ring of the stator and having the angle of 180 DEG between them, a circular type commutator, and a circular plate shape rotor formed of three rotor coils and a rotary shaft. The rotor is fixed to the upper and lower covers by the center rotary shaft, and the rotor is rotated by asymmetrically arranged three rotor coils for thereby generating vibrations. |
