On the premise of normal work, saving material cost-effective as far as possible.The madial wall of body 11 be provided with it is multiple towards its center of circle around
Bar 12.The end of winding 12 is extended with covering fin 121 towards both sides.Space is provided between covering fin 121.Multi-disc covers the wing
Piece 121 forms circular cavity, and in post-production excitation electromotor, circular cavity is used to place rotor, excitation electromotor rotor and stator
Mutual cooperation work.Winding 12, body 11 and covering fin 13 are structure as a whole.The material of stator core 1 is cold-rolled steel sheet.Around
The end of bar 12 offers the cavity 122 for accommodating permanent magnet 7.Permanent magnet 7 is fastened in cavity 122.Permanent magnet 7 is used to produce
Magnetisation field, ensure the normal work of whole excitation electromotor stator.The madial wall of covering fin 121, winding 12 and body 11 is formed
Cavity be groove for placing winding 2.Insulating paper 4 is equipped with groove.Insulating paper 4 is located at relative both sides and covering in groove
The inner side of fin 121 offsets, and covering fin 121 limits insulating paper 4 on the center of circle direction of body 11；Another pair phase of insulating paper 4
To both sides protrude from body 11, the both sides that insulating paper 4 protrudes from body 11 are provided with kink 41, kink 41 and body 11
End face is offseted, and insulating paper 4 is limited on the direction of the vertical end face of body 11.Thus, insulating paper 4 is fixed in groove, prevented
