Beschreibung
Zusammenfassung:	The present invention relates to an electric automotive fluid pump (10) comprising an electronically commutated motor (42) with a motor rotor (46) being permanently magnetized and stator coils (50), and a motor electronics (58) for electronically commutating and driving the stator coils (50) of the motor (42). The electric automotive fluid pump (10) further comprises a pumping unit (82) which is arranged axially between the motor electronics (58) and the motor (42), a rotor shaft (54) mechanically connecting a pump rotor (78) of the pumping unit (82) with the motor rotor (46), wherein the pump rotor (78) comprises a pump rotor body (78') and at least one permanent magnet pole (N, S), which cooperates with at least one stationary hall sensor (70).
