摘要： 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.

摘要： Disclosed is a poly-phase reluctance electric motor with transverse magnetic flux, which electric motor is composed of a stator and a rotor. The stator is composed of a housing (1) and a number m of phase armature units which are arranged within the housing (1) along the axial direction successively, with each of the phase armature units being staggered at an electrical angle of 360°/m along the circumferential direction. Each phase armature unit is composed of a unit armature iron core, an armature coil (2) and permanent magnets (3), with the unit armature iron core being composed of a first annular iron core segment (6), a second annular iron core segment (7) and a third annular iron core segment (8). The armature coil (2) is embedded within an annular space formed among the first to the third annular iron core segments (6, 7, 8). The permanent magnets (3) are fixedly arranged on the inner surfaces of the first and the third annular iron core segments (6, 8) along the circumferential direction in a manner of the N pole and the S pole spaced successively. The pole distance τm between every two adjacent permanent magnets (3) on the same annular iron core segment and the tooth distance τp between the rotor teeth (5) arranged along the circumferential direction fulfil 2τm=τp. The electric motor eliminates the mutual inductance between phases, improving the precision with which the current and electromagnetic torque of the electric motor can be controlled and the dynamic characteristics of the system, and improving the reliability and safety of the motor as a result of the permanent magnets (3) being located on the stator.
