Abstract
A brush assembly for use in a homopolar dynamoelectric machine includes a plurality of contact elements extending into slots of a movable brush holder. Resilient tubular members extend through each of the brush holder slots and lie adjacent to the bottom of the slots. The brush holder is movable with respect to a brush box that includes an array of openings positioned to receive the contact elements. An actuating rod for moving the brush holder with respect to the brush box and projections, on opposite sides of each slot, for retaining the contact elements within the brush holder slots are also provided. When the brush holder is lowered such that the contact elements make sliding electrical contact with the surface of a rotating rotor of the homopolar machine, the resilient tubular members provide a spring force which keeps the contact elements in intimate sliding contact with the rotor surface.
