摘要： A power tool includes a flux ring with an annular member. At least one molded magnet is received on the annular member. An anchor is on the annular member to retain the at least one magnet on the annular member. The anchor is unitarily formed with the annular member to receive the magnet. The anchor includes at least one bend with a reinforcement member at the at least one bend.

摘要： A field case housing has a substantially cylindrical wall segment, an end segment and a flange all having a substantially constant wall thickness. The flange has reinforcing ribs connected to the wall segment and aperture reinforcing bosses. The end segment, the wall segment and the flange are formed as a single, integral part adapted to reduce warping of the housing during molding. A cylindrical guide member is located in the field case housing and a conical guide member is located in the fan baffle. The cylindrical guide member is adapted to insure a screw passing through the cylindrical guide member is guided to a point within the conical guide member. The fan baffle has a transverse wall with an aperture and guide walls extending adjacent the aperture. The guide walls are adapted to guide an armature past the magnets without contacting and damaging them.

摘要： Anelectrically conductive brush box is located against the upper surface of a base and has crimping tabs located against an oppositely disposed crimping surface. The base is formed of high temperature resistant plastic. A field case housing has a seat with a retention member adapted to retain the base against the seat. A screw is threaded into the field case housing such that the head presses against a surface of the base member to retain the base member in the seat. The screw member is located in non-contacting relationship with the electrically conductive brush box. A spacer member is adapted to space the portion of the crimping tab against the crimping surface away from the field case housing. The brush box includes a biasing member holder and the crimping tabs are located adjacent the holder.
