Abstract
An electrically commutated DC motor () for a liquid pump () with a pump housing () with a suction connector () and a pressure connector () for connection to a hydraulic circuit, an essentially disk-like pump rotor () mounted to rotate in the pump housing, consisting of an impeller () with several pump vanes and a permanent magnet (), a partition () separating a pump space () from a dry space (), in which the partition is arranged in an axial gap () between the pump rotor () and several axially aligned wound stator poles () of the DC motor. The present invention configures a DC motor, so that it can be installed simply and reliably, is designed particularly robust and therefore has a very long operating lifetime.
