This paper describes experimental and analytical study on energy conversion from vibrational energy to rotational one by an oscillatory rotor, which will rotate in one direction when it is oscillated. The characteristics of motion of an oscillatory rotor on a vibrating table are investigated experimentally. Consequently, for suitable range of exciting frequency, an oscillatory rotor rotates at an approximately constant speed. The fundamental mechanism of rotation is that the vertical vibration induces parametric oscillation of an oscillatory rotor. In particular vibration of the axis circumference on minimum moment of inertia is effecting rotation. Then the characteristic of an oscillatory rotor converts shaking motion into rotational motion in turn.
