The invention relates to a novel brushless
motor fuel pump. In the technical scheme, a brushless
motor controller is connected outside the
fuel pump, namely one end of an electronic plug-in part is connected with a
fuel pump motor
stator, and the other end of the electronic plug-in part is connected with the brushless
motor controller; a vehicle-mounted power supply is connected outside and an
integrated circuit is connected inside a
voltage-stabilizing and filtering circuit in the brushless
motor controller; the
integrated circuit is respectively connected with a
peripheral resistance-
capacitance circuit and a three-phase bridge
inverter; and a starting circuit and three-phase feedback
voltage in the
integrated circuit are connected with a phase locked logic
phase change circuit respectively. The defects that a
position sensor has low sealing property, ages quickly, is corroded, and the like are overcome. By a counter potential reversing technology, the pump can effectively
resist fuel
corrosion and fuel electric conduction, can be suitable for various liquid fuels such as
gasoline,
methanol,
ethanol and the like, has high reliability, small volume, long service life and low price, is convenient to install, reduces a motor gap, and improves motor output and
motor efficiency, and the volume of a pump body is reduced.
