Abstract

The invention discloses a brushless electric fuel pump with a built-in controller. The brushless electric fuel pump comprises a pump case and a controller assembly, a bearing, a stator assembly, a rotor assembly and a worm wheel which are arranged in the pump case, wherein the controller assembly further comprises a bracket, a controller, a radiating fin and a plastic sleeve; the bracket is sleeved with the pump case; the radiating fin is arranged on the bracket; the controller is jointed with the radiating fin; the plastic sleeve is sleeved on the outer side of the controller and sleeved with the bracket; one end of the bearing is connected with the bracket; the stator assembly and the rotor assembly are sleeved on the outer side of the bearing; the stator assembly is connected to the lower end of the bracket; the rotor assembly is sequentially connected to the lower end of the stator assembly; and the worm wheel is connected to the other end of the bearing. The brushless electric fuel pump disclosed by the invention has the advantages of high radiating efficiency, long service life, high reliability, high pump efficiency and low cost and can adapt to various types of oil products.

Description

technical field [0001] The invention relates to an electric fuel pump, in particular to a brushless electric fuel pump with a built-in controller and high heat dissipation efficiency and high reliability. Background technique [0002] The brushless electric fuel pump includes a controller and a pump body. The controller is used to obtain level power from the ECU, and convert the DC regulated power supply into a three-phase alternating current through its internal 6 MOS tubes and transmit it to the internal stator of the pump body. The winding forms electromagnetic induction, which is transmitted to the permanent magnet on the rotor in the pump body to make the rotor run, converts electrical energy into kinetic energy, and drives the turbine in the pump body to rotate at high speed together, thereby realizing oil pumping. At present, due to the size of the pump body and the high rated electric power, it is difficult to overcome the vibration and sealing inside the pump. The c...
