Electrically driven pump, e.g. for motor vehicles, has electric motor in form of disk rotor with magnetic ring mounted on pump wheel in region through which fluid flows

摘要

The device (10) has an electric motor (16) in the form of a disk rotor with a magnetic ring (22) mounted on the pump wheel (14). The magnetic ring is arranged in a region through which a fluid flows and the stator (26) of the electric motor is arranged outside the fluid-carrying region. The stator can be mounted outside the pump housing.
