Embodiment Construction
[0027] The present invention will be further explained below in conjunction with the accompanying drawings.
[0028] The design principle of the present invention is as follows: The disc-type double-stator hybrid excitation motor described in the present invention realizes hybrid excitation based on the principle of magnetic field modulation, and 2p are evenly arranged along the circumference on the annular disc-shaped rotor 1 A permanent magnet, and two permanent magnets with opposite polarities form a group with iron core poles at intervals, such as figure 2 shown. The excitation winding is located on the inner stator, and the corresponding alternating current is passed through to generate the excitation magnetic field. Since the permanent magnet base and the iron core pole interval made of non-magnetic materials 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 gene...
