Abstract: A one-piece generator housing locates and secures the generator stator assembly, rotor bearings, and brush holder, and provides for attachment of the housing assembly to the engine interface. The disclosed one-piece housing completely encloses the stator and rotor assembly of the generator. An embodiment of the one-piece generator housing is applied to welding machine applications that use an in-line engine. With this type of engine, the power take-off (PTO) is normally the engine flywheel, and the variety of engine interfaces to which to mount the generator become more diverse. In an embodiment, the rotor has a flange with integral cooling fan blades that bolts to the flywheel. A shorter adapter is used in order to access the fasteners that attach the rotor shaft to the flywheel. The housing attaches to the adapter using cast-in bosses and bolts.
