More Information
Summary:The utility model relates to an armature pressing ring structure for a brushless exciter which is characterized in that a non-oriented silicon steel sheet punching ring is included. A tooth pressure sheet ring is connected in the non-oriented silicon steel sheet punching ring, the tooth pressure sheet ring is matched with a pressure ring by a bayonet, and the surface of the pressure ring which is contacted with the tooth pressure sheet ring in a compressed way is provided with a conicity ranged from 0.1 mm to 1.0 mm. The utility model has the advantages that the manufacture is convenient, the cost of the brushless exciter is greatly lowered, and the casting defects that bubble inclusion may exist in an original casting, and the like are avoided, as well as the reliability of a product is enhanced.
