When the permanent magnet motor is energized, the pump body is driven to rotate, and fuel is sucked in from the fuel inlet, flows through the inside of the electric fuel pump, and then presses out from the fuel outlet to supply fuel to the fuel system. The fuel flows through the inside of the electric fuel pump to cool the armature of the permanent magnet motor, also called the wet fuel pump. The motor part of the electric fuel pump includes a magnet fixed on the shell, an armature that generates electromagnetic torque, and a brush device installed on the shell. The brush is in contact with the commutator on the armature, and its lead wire is connected to the post on the shell, and the voltage that controls the electric fuel pump is led to the armature winding. Both ends of the shell of the electric fuel pump are crimped and riveted, so that the components are assembled into a non-detachable assembly.Package Includes:1 x Fuel Pump When shopping, please pay attention to the size and dimensions of the product to ensure that it meets your needs.
