This paper proposes a partial zero-power controller to move a levitated body under energy-saving conditions using a magnetic levitation device that allows three-dimensional motion. Modeling was specifically performed to control the feedback of each independent x-, y-, and z-direction in a controlled system. The z-direction was controlled by using voltage integration with zero power while the x- and y- directions were manipulated with positioning control. After doing experiments on horizontal displacement on the three points on the x-z plane, we verified that the levitated body smoothly shifted to its required value for the x- and y- directions and it moved with zero-power input voltage toward the z-direction.
