Abstract
A commutator is formed by providing an electrically insulating commutator body. First and second areas are defined on the commutator body covering a brush contact surface in an alternating manner. At least the surfaces of the first areas are formed of laser direct structured material. The first areas are treated by a laser to form metal particle layers. Conductive layers are formed on the metal particle layers by a plating process to form commutator segments. Terminals are connected to the conductive layers for connecting the commutator to rotor windings.
