    摘要： A magnetic suspension planar motor comprises a structure of superconductor excitation. A primary base plate is in a shape of board. Armature windings are fixed on an air gap side of the primary base plate. A secondary base plate in a secondary structure is evenly divided into 2 h*2 h magnet cells. 2 h2 superconducting magnets are respectively fixed in the magnet cells on the secondary base plate, which resembles a checkerboard pattern. The superconducting magnets are adjacent to each other, neither in a horizontal direction nor in a vertical direction. The superconducting magnets are magnetized parallelly, and magnetization directions of the superconducting magnets are perpendicular to a surface on an air gap side of the secondary base plate. The superconducting magnets in a same row or column have same magnetization directions, and the superconducting magnets in adjacent rows columns have contrary magnetization directions. A cooling container shields all of the superconducting magnets.
