Abstract

See full text

An automotive electric fluidic pump includes a brushless and electronically commutated electric drive motor. The electric drive motor includes a permanent-magnetic motor rotor which rotates around a rotation axis and includes rotor poles, stator-sided electro-magnetic coils, a printed circuit board with openings, at least two stator-sided Hall sensors arranged on a proximal side of the printed circuit board to face the permanent-magnetic motor rotor, and a ferromagnetic back iron member arranged at a distal side of the printed circuit board to provide a direct magnetic coupling of the Hall sensors with each other. The Hall sensors are arranged eccentrically to detect axial magnetic fields of the rotor poles. The ferromagnetic back iron member comprises axial protrusions. An axial protrusion extends into an opening of the printed circuit board. Each axial protrusion faces a Hall sensor.
