Abstract: 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.

Abstract: 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 ?m of the permanent magnet in the secondary structure have a relationship as follows. Lc=(2k+1)?m, wherein k is a natural number.

Abstract: A multi-phase reluctance electric motor with transverse magnetic flux which includes a stator and a rotor. The stator comprises a housing (1) and a number m of phase armature units, each being staggered at an electrical angle of 360°/m along the circumferential direction sequentially in the housing (1) along the axial direction and comprises an armature iron core, an armature coil (2) and permanent magnets (3). The armature coil (2) is embedded within an annular space formed among first, second and third annular iron core segments (6, 7, 8) of the armature iron core. The pole distance ?m between two adjacent permanent magnets (3) on the same segment and the tooth distance ?p between the rotor teeth (5) along the circumferential direction fulfil 2 ?m=?p. This motor eliminates mutual inductance between phases, improving control precision of current and electromagnetic torque and dynamic characteristics of the system.
