Abstract
A contact assembly of an alternator including an interior chamber, which houses a first end of a rotor shaft having an axis of rotation, first and second bearing assemblies coaxially aligned with the rotor shaft and electrically isolated from one another; and at least one spring member coaxially positioned with respect to the rotor shaft within the chamber. The spring member(s) exerts resistive forces into at least one of the first and second bearing assemblies and support structures within the interior chamber in order to compressively sandwich the first and second bearing assemblies within the interior chamber. The contact assembly may also include capacitors electrically connected to the bearing assemblies.
