ABSTRACT:
To improve resistance to vibration and shock, while permitting ready access for replacement of brushes of an alternator, the remote end shield (8) is formed as a reinforced plastic injection-molded or pressure-cast structure, integral with a hub for the remote bearing of the rotor and the brush holder for the brushes engaging slip rings (10, 11) on the rotor shaft. An opening (33) extending from approximately the radially outermost part of the brush holder to the end of the remote bearing plate permits access to the brushes for maintenance or replacement. The surface region of the end plate is formed with an engagement surface (35) against which a voltage regulator can be attached, having a projecting terminal blade electrically connected with one of the brushes by a compression spring and/or an eyelet rivet and a pigtail attached thereto.
