An electric fluid pump for a motor vehicle includes an electric drive motor which is brushless and electronically commutated. The electric drive motor includes a permanent-magnetic motor rotor having a motor shaft and at least two rotor poles, each of the at least two rotor poles having one permanent magnet embedded therein, a plurality of stator-side magnetic coils, at least two sensor magnets each emitting an axial magnetic field and each having polarities, and at least one Hall sensor which is arranged to lie eccentrically in a transverse plane so that the at least one Hall sensor detects the axial magnetic fields of the at least two sensor magnets. The at least two sensor magnets are magnetized diametrically. The at least one Hall sensor is arranged to detect the polarities of each of the at least two sensor magnets during one revolution of the permanent-magnetic motor rotor.
