Abstract
According to the present invention, there may be provided an actuator comprising: a shaft comprising a thread; a rotor surrounding the shaft; a stator arranged outside the rotor; a moving portion coupled to the thread of the shaft; a housing that holds both ends of the shaft; and a substrate that is arranged on the housing and comprises a sensor portion for sensing the position of the moving portion, wherein the moving portion comprises a magnet; the sensor portion comprises a first sensor and a second sensor for sensing the amount of magnetic flux change following the position of the magnet; the first sensor generates a first signal including an area in which the measured voltage increases linearly as the magnet moves away from the first sensor; and the second sensor generates a second signal including an area in which the measured voltage decreases linearly as the magnet moves away from the second sensor.
