ABSTRACT:
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.
