Method of making a flat commutator |
摘要 |
A flat commutator for an electric motor of a vehicle fuel pump. The commutator, is made with a one-piece carbon ring having a flat outer face, a one-piece conductor ring underlying the outer face of and embedded in the carbon ring, and a housing of a plastic insulating material molded on the rear face and the inner and outer edges of the carbon ring and adapted to mount the commutator on a motor armature. A plurality of circumferentially spaced apart grooves extend radially and axially completely through both the carbon ring and the conductor ring to provide a plurality of individual sintered carbon segments each with a separate conductor for electrically connecting the segments with armature coils.
