  • Patent number: 11025109
    Abstract: A permanent magnet rotor of an electric motor, includes a laminated core having magnet pockets, the laminated core being composed of two partial laminated cores. A plurality of permanent magnets are held in a force-fitting manner in magnet pockets of the laminated core, the magnets extending over both partial laminated cores. Sheet metal tongues, which maintain the force fit of the permanent magnets, are deflected in the first partial laminated core in a first axial direction and in the second partial laminated core in a second axial direction opposite to the first direction, wherein the partial laminated cores consist of stamped metal sheets and the permanent magnets are pressed into the magnet pockets in the stamping direction.

  • Patent number: 10907644
    Abstract: A pump impeller consisting of at least three different material regions, wherein an impeller wheel with a hollow shaft defines a first material region, a bearing component defines a second material region, and a permanent magnet defines a third material region. The invention furthermore relates to a method for producing the pump impeller, and to a centrifugal pump with the pump impeller. The object of the invention is to provide a robust construction, optimal venting, secure attachment of the bearing component, economic production, and a possibility of axial length tolerance compensation given a pump impeller with plastic-bonded permanent magnets. Furthermore, an optimally accurate unbalance-reduced connection between the bearing component and the magnet material should be producible.

  • Patent number: 10323642
    Abstract: A pump motor having a permanent magnet rotor, a containment shell, a wound stator, a motor housing, a pump head, a shaft, which is secured in the containment shell on the one hand and in the pump head on the other hand, and a fixed bearing, which is pressed or injected into the permanent magnet rotor and rotatably mounts it on the shaft. The pump motor provides a reliable and economically producible bearing of the permanent magnet rotor on the shaft in a generic pump motor, in which the bearing abutting uniformly against the shaft over the entire bearing length and during a complete rotation can be achieved, small angle errors can be compensated, and noises can be reduced.

  • Patent number: 9780607
    Abstract: A stator core for an electronically commutated DC motor with an internal rotor having a plurality of radially inwardly directed pole cores which at their periphery are integral with back iron segments and the back iron segments are integral with adjacent back iron segments via webs, wherein the back iron segments alternate with the webs and jointly form a seamless closed one-piece ring. A method of ensuring that in the case of a stator core of this class, upon a reduction of the stator diameter and reduction of the pole distances after winding, a clearly defined end position of the adjoining regions can be assumed, and that for this process, only minimal forces are necessary, in which damage to the stator core is not to be expected, and that at the end of the process only a very small and uniform air gap remains at a lowest possible spring-back.
