PURPOSE:To simplify the control of acting points of the levitating force, driving force, and brake power by constituting an inductor for transporting a nonmagnetic body in levitated state from the poles arranged in matrix form and wound coils and controlling the phase of the alternating electric current supplied into the coils. CONSTITUTION:Poles P1-P3 are grouped into a group Gx1, and poles P4-P6 are grouped into Gx2, and poles P7-P8 are grouped into Gx3, and the inside of each group Gx-Gx3 is connected in common. The R-phase electric current of three-phase electric power source is supplied into the coils C1-C3 of the group Gx1, and the S-phase electric current is supplied into the coils C4-C6 of Gx2, and the T-phase electric current is supplied into the coils C7-C9 of Gx3. Therefore, a shifting magnetic field directing from the group Gx1 to Gx3 is generated, and a nonmagnetic body on an inductor 10 is excited to the Dr1 side. When the phase of the supplied electric power source is set in the order of T, S, and R, the nonmagnetic body can be excited to the Dr2 side. If group assortment is performed as Gy1-Gy3, the magnetic body can be excited an Dr3 and Dr4. Therefore, the acting position of force can be changed simply.
