摘要： A centrifugal pump comprising a pump housing made of injection-molded plastics with a first housing part, which is designed as a single piece with a suction connection and a pressure connection, and comprises a sealing area, by means of which said first housing part is joined in a liquid-tight manner to a second housing part, that receives an electric motor, and a motor housing part. In this centrifugal pump, very good leak tightness is achieved with minimum number of parts, minimum weight and minimum assembly costs with universal applicability without impairing the visual overall impression of the centrifugal pump. This objective is achieved in that the second housing part is made of a material that is permeable to laser light of a wavelength or a wavelength range, and the first housing part is made of a material that absorbs the same laser light, and the first housing part and the second housing part are heat-sealed to one another.

摘要： A rotary pump with a plastic pump housing, that can be processed by injection molding, with a first housing part defining a pump space, which is connected to a second intermediate housing part accommodating an electric motor with a wound core stator. The rotary pump includes a plastic split core, the wound claw pole stator being mounted on the split core and a permanent magnetic rotor being mounted to rotate within the split core. A plastic motor housing part defines a motor space, wherein at least three axial and parallel split core ribs are provided between the split core and the claw pole stator, the ribs being distributed about the periphery of the split core at predetermined angles relative to each other. A return ring has first and second end sections, the return ring being connected to the wound claw pole stator, so that the first and second end sections are welded to each other. The stator is press-fit onto the split core via the ribs. At least three axial-parallel housing ribs protrude radially inward and are formed with the motor housing part, the axial-parallel housing ribs being distributed on the inside periphery of the motor housing part. Finally, the stator is press-fit into the motor housing part via the housing ribs.

摘要： A stator (10) for an electronically commutated DC motor with a number of stator poles (1) formed as individual parts, consisting of a pole core (25), pole shoes (26) and return sections (27), in which the return sections (27) of the stator poles (1) have intermeshing profiles, on which they lie against each other, so that the return sections form a hollow cylindrical return (35) with each other, in which the pole cores (25) connect to the return sections (27) directed radially inward. The individual stator poles are each provided with an insulation and a winding, and the wound stator poles (1) are held together by a retaining part that does not serve as motor housing. The task of the present invention is to provide a stator for an electrically commutated DC motor, which can be mounted simply and reliably, and which facilitates assembly of the stator in the motor housing. This task is achieved by providing that the retaining part is a metallic clamping ring (4), which is positioned under bias around the entire periphery of the hollow cylindrical return (35) and tightens the stator poles (1) to each other.

The electronic components are arranged on an electronic circuit board aligned at right angles to an axle and parallel to a base of the split case. The electronic circuit board is in heat conducting contact with the base. The task of the invention is to cool electronic components sensitive to heat in a simple way and with a high degree of efficiency such that a simple installation of the electronic components is guaranteed and only a small number of parts is required, the construction space being as small as possible. According to the invention, this problem is solved by the fact that one or several conductors of the electronic circuit board are in heat conducting contact with the base.

摘要： A permanent magnet rotor having a shaft, a hollow cylindrical permanent magnet and an elastic connecting medium between the shaft and the permanent magnet. The permanent magnet is arranged co-axially around the shaft to ensure that the permanent magnet is mounted securely, that it is not damaged during large temperature fluctuations, and that it is not deflected impermissibly from the axis of rotation in case of heavy radial load. A simple installation process uses a mechanical connection between the shaft and the permanent magnet. This task is performed by virtue of the fact that an elastic connecting medium is arranged along the periphery of the shaft at several first areas in which the distance between the shaft and the permanent magnet is enlarged. These first areas are separated from the second areas in which the distance between the shaft and the permanent magnet is minimized but not zero.
