Abstract
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.

A linear actuator using two rotors, comprising:
- 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 actuator, comprising:
- a first rotor;
- a second rotor, wherein said first and second rotors are 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, wherein the linear motion unit moves linearly by engagement with the driving power transmission unit when the first and second rotor differ in angular velocity.
