A permanent magnet synchronous planar motor with a structure of concentric winding comprises a primary structure, a secondary structure, and an air gap. Armature windings in the primary structure of the permanent magnet synchronous planar motor are fixed on an air gap side of the primary base plate in a shape of board, wherein the air gap side is defined as a side adjacent to the air gap. The armature winding of each phase comprises a plurality of concentric rectangular coils. The rectangular coils are connected in series in turn from inside to outside, and winding directions of the two adjacent rectangular coils are opposite. A distance Lc between center lines of two opposite sides of each of the rectangular coils and the polar distance τm of the permanent magnet in the secondary structure have a relationship as follows. Lc=(2k+1)τm, wherein k is a natural number. |
