Abstract: A one-piece end bell and brush holder for a dynamoelectric machine comprises a cup-shaped cap member molded of electrical insulating material. The cap member has a flat, annular base with its central opening accommodating the rotating shaft of the machine, and a circular outer wall shaped to have interfitting engagement with a cylindrical housing of the machine. Encircling the central opening is a circular inner wall that extends axially from the base a distance sufficient to encompass the commutator of the machine. The inner wall has four equispaced openings formed therein that permit brushes to move radially therethrough for engagement with the circumference of the commutator. The brushes are mounted in brush boxes, each of which includes a pair of side walls adjacent to and embracing the opening in the inner wall and extending radially outward from the inner wall to the outer wall.
