Brushholder supporting structure

摘要

A brushholder is adapted to be secured to the frame of a dynamoelectric machine by means of either insulated steel studs or resin-bonded fiber glass studs. The frame of the brushholder contains at least two holes which are spaced apart and in parallel. Each hole is adapted to receive one end of the steel stud as an interference fit or one end of the fiber glass stud as a clearance fit. An adhesive is used to bond the fiber glass stud in the hole. The wall surface defining the hole contains groove means which helps key the adhesive to the surface but does not detract significantly from the interference fit of the steel stud.
