Abstract: 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), in which the partition is arranged in an axial gap (12) between the pump rotor (6) and several axially aligned wound stator poles (14) 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.

Abstract: 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. This task is solved according to the invention by the characterizing features of claim 1.

Abstract: Multi-phase motor, in particular, stepping motor or synchronized motor, with a rotor and stator parts that are essentially arranged concentrically with respect to the rotor and that, in each case, have a core and a coil, consisting of winding wire, and wound up upon the core, as well as a plug part with plug pins or a printed circuit board with strip conductors for electrical connection to a power supply source, where the winding wires essentially are connected directly to the plug pins or the strip conductors and where, between each coil and the plug part or the printed circuit board, there is provided an electrically insulating connecting piece which receives a section of the pertinent winding wire.

Abstract: A permanent magnet rotor, intended for an electric motor, comprises a permanent magnet ring, which is held by a plastic support element and a sliding bearing. The permanent magnet ring comprises a compressed plastic-bonded rare earth magnet. The sliding bearing is made of a sintered material. The plastic support element can be produced in an injection mold. The permanent magnet ring includes a cylindrical receptacle for the sliding bearing and is made as one piece with a pinion. The plastic support element envelops the permanent magnet ring at least partially in the axial and radial direction and the permanent magnet ring can be injected simultaneously as an insert in the injection mold.

Abstract: An actuator for heating, cooling and climatic valves in vehicles includes a gear housing, an electric motor placed therein, a reduction gear acted on by the turning moment of the electric motor, a drive shaft and a position determining device connected thereto. A slide carrier with teeth on its perimeter allows use of an adjusting tool to make adjustments to the position determining device. Other fixing areas are provided on the slide carrier and in the driven gear which make it possible to form lock the slide carrier to the driven gear by means of a rapidly hardening substance without damaging the gear.
