[0027] The present invention will be further explained below in conjunction with the drawings.
[0028] The design principle of the present invention is as follows: the disk-type dual-stator hybrid excitation motor of the present invention realizes hybrid excitation based on the principle of magnetic field modulation, and 2p is evenly arranged along the circumference on the annular disk-shaped rotor 1 One piece of permanent magnet, and two permanent magnets with opposite polarities are a set of iron core poles spaced apart, such as figure 2 Shown. The excitation winding is located on the inner stator to generate the excitation magnetic field with corresponding alternating current. Since the permanent magnet base made of non-magnetic material and the iron core poles face the excitation winding side, it is known that the magnetic permeability of the iron core is much greater than that of the base. The magnetic field lines generated by the excitation winding will gather at the core ...
