Abstract
A commutator assembly for an electric motor includes a commutator having commutator segments arranged circumferentially, brushes contacting the commutator segments, and an equalizer connecting commutator segments so they have the same electric potential, the equalizer including printed circuit boards with insulating substrates and a connecting plate having an electrically conducting film on the insulating substrate, electrically connected to the commutator segments.
