An assembled commutator has an insulating commutator body having a cylindrical outer surface, radially extending axial support means and an axial extension on the opposite side of the axial support means to the cylindrical outer surface. Three commutator segments each have an arcuate brush-contacting portion seated on the cylindrical outer surface of the commutator body, an axial terminal stem extending through a passage formed in the axial support means, and a radial terminal stem seated in one of three equiangularly extending radial grooves formed in the axial support means. An apertured insulating clamping member which is press-fitted on a first part of the axial extension clamps an apertured varistor which is seated on a second part of the axial extension in electrically conductive engagement with the radial terminal stems.
