AUTOMOTIVE ELECTRIC LIQUID PUMP

摘要

The invention refers to an automotive electric liquid pump (10) with a pump housing (12) and a rotor (13) defining the longitudinal rotor axis (17). The automotive pump (10) comprises•an electric motor (20) including stator coils (22) at one longitudinal end of the pump housing (12),•a power electronics chamber (50) with power semiconductors (56) for driving the stator coils (22), the power electronics chamber (50) being arranged at the other longitudinal end of the pump housing (12),•a pump chamber (30) wherein a pump rotor (36) driven by the electric motor (20) is rotating to pump a liquid from a pump chamber inlet (43) to a pump chamber outlet (45), and•a metal separation wall (40) in transversal plane, the separating wall (40) separating the pump chamber (30) from the power electronics chamber (50).
