Since their discovery, many attempts have been made in industrial applications of superconducting oxides whose critical temperature(<i>Tc</i>) is higher than the boiling temperature of liquid nitrogen. In particular, levitation technologies with the pinning effect have been drawing attention, which is the basis of many applications, including magnetic bearings, flywheels, and non-contact transportation systems. This paper describes a new type of magnetic levitation type surface motor using the bulk high-<i>Tc</i> superconductor and electromagnets. The present system consists of the stator constructed by two-dimensional array(8×4) of small electromagnets with 10×10mm<sup>2</sup> pole-face and the mover made of styrofoam containing YBaCuO superconductor with the size of 42×42mm<sup>2</sup> prepared by MPMG (Melt-Powder-Melt-Growth) method. The mover can be shifted between the nearest neighbor poles on the array by flipping the polarity of electromagnets, without any contact. By the control combined with PC, continuous shifts toward forward and backward directions were realized.
