A device for connecting an electric motor intended for use in a fuel tank, in particular of a motor vehicle, with connection contacts carbon brushes sliding over an armature of a rotor, and electrical leads arranged between the connection contacts and the carbon brushes. The electrical leads have a sheath made of polytetrafluoroethylene.

Device for connecting an electric motor intended for use in a fuel tank, in particular of a motor vehicle

The invention relates to a fuel pump which comprises an electric motor. Said electric motor is provided with carbon brushes () that cover a plurality of lamellae () of a collector (). Grooves () in an armature () include sections of a plurality of coils (), thereby particularly reducing erosion of the carbon brushes ().

Fuel pump comprising an electric motor

An electrically commutated motor for a fuel pump having a rotor connected to a shaft and having plastic-bonded ferrite, with a fuel-resistant shaped body formed by the plastic-bonded ferrite, and a magnetic return element adjustable in relation to the shaped body.

Motor for a fuel pump

An electronically controlled electric motor has, as position sensors ( ), coils ( ) which are arranged in a stator ( ) and opposite permanent magnets ( ) of a rotor ( ). The coils ( ) are produced integrally with connecting leads ( ). This allows the electric motor to be used in an environment with solvents. Furthermore, the electric motor is of a particularly inexpensive design.

Electronically controlled electric motor provided for use in an environment containing solvents

In an electric motor, through which fuel flows, an armature core bundle of a rotor has a hose-like casing. This hose-like casing is manufactured from a fuel-resistant material and protects the armature core bundle against corrosion. An unbalance in the rotor due to the hose shape of the casing is kept particularly low.
