<p>A unitary end bell (66) includes a body (90) and a bridging section (92) and is assembled with a laminated stator stack (74) in the formation of a stator subassembly (150). End bell (66) is formed with base surfaces (118) at one end thereof which directly engage adjacent portions of lamination stack (74) and insulate these portions from coil windings (152). End bell (66) also has wire-retaining shrouds (110) which support and confine the coil windings (152) in their wound configuration. Bridging section (92), which straddles the other end of body (90), is formed with brush box channels (120) and a nest (138) for supporting an armature bearing (218). Laminations (76) of the stack (74) are held together and assembled with the end bell (66) by the coil windings (152) themselves, which are wound after the loose laminations (76) and the end bell (66) are preassembled together. A shroud support (168) and a pallet (212) may be employed to aid such assembly. <IMAGE></p> |
