Permanent magnet harmonic composite exciter stator

The utility model relates to a permanent magnet harmonic composite exciter stator, comprising an exciter stator yoke formed by laminating a plurality of exciter stator yoke punching sheets; the composite excitation magnetic pole is formed by laminating a plurality of composite excitation magnetic pole punching sheets; the electro-magnetic pole is formed by laminating a plurality of electro-magnetic pole punching sheets; wherein the exciter stator yoke punching sheet is annular, and the inner ring side of the exciter stator yoke punching sheet is provided with a boss protruding towards the center direction; the composite excitation magnetic pole punching sheet and the electric excitation magnetic pole punching sheet are respectively provided with a groove matched with the boss. Through cooperative connection between the groove and the boss, the composite excitation magnetic pole and the electric excitation magnetic pole are assembled and connected to the exciter stator yoke. The composite excitation magnetic p
