Patent attributes
An electrically commutated DC motor (1) for a liquid pump (2) with a pump housing (3) with a suction connector (4) and a pressure connector (5) for connection to a hydraulic circuit, an essentially disk-like pump rotor (6) mounted to rotate in the pump housing, consisting of an impeller (7) with several pump vanes and a permanent magnet (8), a partition (11) separating a pump space (9) from a dry space (10), the partition being arranged in an axial gap (12) between the pump rotor (6) and several axially aligned stator poles (14), each provided with an insulation element (15) and stator windings (16). The task of the present invention is to configure a DC motor, so that it can be installed simply and reliably, is designed particularly robust and therefore has very high lifetime.
