    摘要: A power tool includes a motor with a flux ring. The flux ring includes a ring member with a first and second end. The ends are positioned with respect to one another such that the ends move towards and away from one another during compressing and expanding of the ring. At least one anchor is unitarily formed with the ring. A pair of magnets are coupled with unitarily formed anchors to couple the pair of magnets with the ring. The magnets are coupled with the ring such that the ring may be compressed and expanded with the magnets secured in the ring.

    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: An electrically 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.

    摘要: A motor end cap and output device housing is provided that includes a motor end plate having an output device attachment area and a output device housing having a motor end plate attachment area. The output device attachment area includes a locking tab that mates with a slot portion in the output device housing to interlock the two together. As a result, the motor end plate can be conveniently attached to the output device housing without requiring extra fasteners.
