摘要： A fluid pump includes an electric motor having an armature with a commutator and a motor frame which supports a pair of permanent magnets which are located radially outward from the armature. The motor frame has a support stem extending axially in a direction away from the commutator. A pump section is rotationally coupled to the electric motor and pumps the fluid. First and second motor brushes deliver electricity to the commutator and are urged into electrical contact with the commutator by a first and second springs. The first and second springs are mechanically grounded to a brush spring retainer fixed to the motor frame. The brush spring retainer includes a central portion having an opening within which the support stem is received in an interference fit. A support arm extends from the central portion such that the first and second springs are mechanically grounded to the support arm.

摘要： A method of manufacturing a commutator. A connector plate is formed with a plurality of connectors arranged circumferentially about a central opening and interconnected by links, with each connector having a terminal portion, a segment portion and a number of anchors, with adjacent segment portions being separated circumferentially by slits. A conductive layer is fixed onto a first face of the segment portions to form a brush contacting surface. The connectors are separated by severing the links. The base is fixed to a second face of the connectors. Then the conductive layer is separated into circumferentially arranged segment parts by cutting radial slots through the conductive layer aligned with the slits, the width of the slots being narrower that the width of the slits to avoid cutting the connectors.

摘要： In a commutator of a rotary electric machine, each of commutator segments has a low-resistive layer made of a low-resistive material and a high-resistive layer made of a high-resistive material having a specific resistance higher than that of the low-resistive material. The low-resistive material contains a carbonic material and a binder. The high-resistive material contains a carbonic material, a binder and an inorganic substance such as boron nitride. A mixing ratio of the inorganic material to the high-resistive material is more than 20 wt %. Alternatively, a brush, which makes contact with the commutator segments, can have the high-resistive layer and the low-resistive layer.

摘要： An electric motor provides a carbon contact member of a commutator from colliding with a brush holder. A projection is formed in the brush holder so that it projects toward an end face of a resin mold of an armature. An end face of this projection, which is opposed to the end face of the resin mold of the armature, is positioned in the axial direction so as to form a clearance between the contact members and the brush holder when the armature is moved toward the brush holder by an external force and the end face comes in contact with the end face. As a result, if shock is applied to the fuel pump and the armature moves toward the brush holder, the contact members of the commutator are prevented from colliding with the brush holder. It thereby becomes possible to prevent the carbon contact members from being damaged.
