This paper describes the rotational motion of a double pendulum to investigate the mechanism. The first pendulum, or the main pendulum is supported free to rotate at one end and at the other end the second pendulum is attached, that rotates at a certain speed with respect to the first one. As a result, the rotatinal motion of the double pendulum is good agreement with the result of limited power of the motor. The calculated results of initial conditions show the lowest speed and the area which is attracted to the limit cycle.
