A superconducting milli-sized linear actuator has been developed. The superconducting actuator consists of a high <i>T<sub>c</sub></i> superconducting slider, electromagnets for driving and levitation, power amplifiers, control circuits and a personal computer with a PIO interface board. The superconducting slider has a concave - convex pattern with a pith of 3mm and the stator has electromagnets with 1.0mm pitch. The electromagnetic forces can levitate and drive the superconducting slider with 4 driving phases. In this paper, various kinds of driving methods are proposed and the best driving method is selected for the actuator. From the results, it is found that just one driving method is useful for the actuator, because the superconducting slider can return to the stable position that corresponds to the driving phase. Using the driving method, the superconducting slider can move in the speed range less than several centimeters per second.
