Motor assembly for fuel pump

The present invention relates to a motor assembly for a fuel pump. More particularly, the present invention relates to a motor assembly for a fuel pump which increases the amount of fuel supplied to an engine without deteriorating motor efficiency by forming an additional flow path in a back yoke and a rotor core or teeth wound by a coil. A motor assembly for a fuel pump according to the present invention includes a rotor core of which center is inserted into a shaft to be fixed; a magnet combined with the outer surface of the rotor core; a stator core which includes the rotor core which faces the magnet, and comprises a cylindrical back yoke and teeth which protrude from the inside of the back yoke; a housing which surrounds the outer surface of the stator core; cutting parts which form a flow path which penetrates the upper and lower surface of the back yoke and transfers fuel; and a coil cover which is inserted into a space between teeth, surrounds a coil wound around the teeth, and allows the fuel to touch the coil.
