Patent ID: 7675204

Claim:
A motor for controlling inverse rotation of a rotor comprising: a stator; a rotor rotated in a first direction by interaction with the stator; a first interference element mounted at the rotor to be rotated with the rotor; a second interference element configured to be engaged with the first interference element to control a rotation of the rotor in a second direction which is an inverse direction of the first direction; and a second interference element operating apparatus supplying rotary force of the rotor to the second interference element such that the second interference element is rotated toward the first interference element when the rotor is rotated in the second direction, wherein the second interference element operating apparatus comprises: a first magnet gear disposed on the rotor; and a second magnet gear rotated by interaction with the first magnet gear, the second magnet gear coupled with the second interference element to provide the second interference element with the rotary force by frictional contact with the second interference element.
