Abstract
Provided is a fuel pump module used for a car, and more particularly, to a fuel pump module with a driver equipped inside a fuel tank capable of solving a problem of space limitation due to the installation of the driver by disposing the driver for controlling a BLDC fuel pump between a flange and a reservoir and mounting it in the fuel tank, minimizing the degradation in performance of the BLDC fuel pump caused by voltage drop and efficiency degradation due to a wire by reducing a length of a wire for electrically connecting the driver with the BLDC fuel pump, and achieving a sufficient heat radiation effect by directly transferring the heat energy generated from electrical devices such as FET, MCU, or the like, mounted in the driver to the fuel in the fuel tank through the case cover.
