Linear actuator using two rotors
A linear actuator capable of inducing a linear motion as well as a rotational motion using only two rotors is provided. The linear actuator includes: first and second rotors connected to respective driving force sources; a linear motion unit formed on the first rotor to be linearly movable; and a driving power transmission unit which is fixed to the second rotor and engages the linear motion unit. A linear motion on a rotor can be easily induced using a relative angular velocity difference between two rotors without an additional driving power source for the linear motion.
