COMMUTATOR AND METHOD FOR FORMING THE SAME

摘要

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.

1. A method of forming a commutator, comprising:
providing an electrically insulating commutator body having first areas and second areas being alternately distributed in a circular manner, at least surfaces of the first areas being formed of laser direct structuring material; forming metal particle layers on the first areas by laser treating the laser direct structuring material; and forming conductive layers on the metal particle layers, the conductive layers on adjacent first areas being electrically insulated from each other.
