An opening and closing motor structure according to the present invention has the reduced overall size and facilitates miniaturization by installing multiple ND magnets on a rotating body adjacent to a rotor part and a stator part to increase rotary power by 15-20% in comparison with a motor in the same size. A power transmission part installed at the front end of a rotary shaft of the rotor part comprises a driving gear arranged at the front end of the rotary shaft of the rotor part; a first driven gear reducing the rotary power of the driving gear in 3-4 times; a second driven gear fixed to the same rotary shaft to integrally rotate with the first driven gear and attached at the bottom of the first driven gear; a third driven gear engaged with the second driven gear and reducing the rotary power of the second driven gear in 4-6 times; and a moving pinion fixed to the same rotary shaft to rotate with the third driven gear. As a result, the opening and closing motor structure is effectively used because the power transmission unit provides greater rotary power by a reduced amount. |
