This paper proposes a new cable-less of micro actuator that operates on the resonance energy of a one-degree-of-freedom model by using an electromagnetic force. The actuator is moved by the difference in inertia force during one period of vibration. A mechanical dc-ac inverter that transforms a dc power supply into an ac power supply was designed. The volume of the prototype cable-less of micro actuator with a dc-ac inverter was about 1 cm^3. Experimental results show that the actuator can move at 4 mm/s in a vertical direction in a one dry cell model. Because the actuator can move only on magnetic substances, it has many possible applications for small pipe inspection, repair, biomedical uses, and machining.
