GENERATOR AND AIR DEFLECTOR

摘要

An improved generator has an improved rotor assembly that includes a rotor shaft defining an axis of rotation, a first pole member and a second pole member mounted on the rotor shaft and a deflector supported about the axis of rotation and having non-magnetic axial extensions. Pole claws of the first pole member and second pole member comprise north and south poles that are intermeshed and spaced apart from one another. The deflector is supported about either of the first end or second end of the shaft and corresponds to the member mounted on the same end of the shaft. The deflector is adapted to rotate with the corresponding member and includes a plurality of non-magnetic axial extensions having a base extending between adjacent pole claws of the corresponding member. The non-magnetic axial extensions provide a substantially uniform circumference creating more desirable airflow as the improved rotor assembly rotates about its axis. The resulting airflow produces less noise as less air impinges against a surrounding stator.
