This paper proposes a new cable-less magnetic micro-actuator that operates on the inertia force of a one-degree-of-freedom model by using electromagnetic force. It has optimal design for the inclination angle of the one-degree-of-freedom model and an appropriate selection of suction force at the actuator support. The mechanical dc-ac inverter incorporates a cantilever beam and the one-degree-of-freedom model that switches under electromagnetic force. The volume of the prototype cable-less micro-actuator with three dry cells was about 1.5 cm^3. Our experimental results revealed that the actuator could move vertically at 18.8 mm/s when the duty ratio of the produced voltage was 46.2%. The operating time for a duty ratio of 26.5% was 36 min, providing a total operating range of 26 m for horizontal travel or 15.5 m for vertical travel. The actuator has many possible applications in small pipe inspections, repairs, and machining because it can move on magnetic substances.
