PULLEY-INTEGRATED CABLE ACTUATOR AND OPERATION METHOD THEREOF

The present disclosure relates to a pulley-integrated cable actuator and an operation method thereof, more particularly to an actuator for operating cables. The pulley-integrated cable actuator includes: a base motor; a sun gear shaft of which the lower end portion is coupled to the center of the base motor, rotating by the motor rotation, and provided with a sun gear; a planet gear set consisting of multiple planet gears that mesh with the sun gear; and a ring gear-integrated pulley where a ring gear is formed on the inner side, meshing with the planet gear, and a pulley for winding a cable is formed on the outer side. The sun gear meshes with the inner space of the planet gear set. The ring gear is integrated with the pulley. The planet gear set is placed inside the pulley, minimizing the volume.
