Abstract: Disclosed is a rotary pump including a magnetic rotor arranged in a pump housing and having a magnetic rotor plane, which rotor is operatively connected to a drive for conveying a fluid. The drive is a bearingless motor having a stator configured as a bearing stator and drive stator and having a magnetic stator plane, wherein the stator bears a drive coil and a bearing coil lying in the stator plane and/or a drive bearing coil. The rotor is magnetically contactlessly journalled within the stator, wherein an axial height (H) of the rotor is smaller than or equal to half a diameter (D) of the rotor so that the rotor is passively magnetically stabilized by reluctance forces with respect to the magnetic stator plane both against axial displacement and against a tilt from an equilibrium position.

Abstract: An electromagnetic rotary drive includes a contactlessly magnetically drivable rotor that is coil-free and free of permanent magnets and that includes a magnetically effective core, and a stator by which the rotor is contactlessly magnetically drivable about a desired axis of rotation in the operating state. The stator has a plurality of coil cores of which each includes a bar-shaped longitudinal limb extending from a first end in a direction in parallel with the desired axis of rotation up to a second end, all the first ends being connected by a reflux of windings generate an electromagnetic rotational field of which each surrounds one of the longitudinal limbs. The coil cores include a plurality of permanent magnets by which a permanent magnetic pre-magnetization flux can be generated.

Abstract: An ultrasonic measuring device for measuring a fluid flowing in a pipe includes a housing and transducers. The housing receives and fixes the pipe, so that the fluid can flow through a central recess in a flow direction. The ultrasonic transducers emit and receive ultrasonic signals. Two first ultrasonic transducers are arranged laterally on a first side of the central recess, and two second ultrasonic transducers are arranged on a second side of the central recess. The second side is opposed to the first side, so that the recess is located between the first and the second ultrasonic transducers, and the ultrasonic transducers are arranged and aligned so that one of the first ultrasonic transducers emits a first measuring signal to one of the second ultrasonic transducers obliquely to the flow direction and receive a second measuring signal emitted by the second ultrasonic transducer obliquely to the flow direction.

Abstract: An electromagnetic rotary drive includes a single-use device for single use and a reusable device for multiple use. The single-use device includes a rotor housing with a rotor, a connecting tube for a fluid, and a single-use component. The rotor housing has an inlet and an outlet, and the rotor is provided in the rotor housing for rotation about a desired axis of rotation defining an axial direction. The rotor can be magnetically driven without contact, and the connecting tube connects the inlet or the outlet of the rotor housing to the single-use component such that in the operating state the fluid flows through the connecting tube. The reusable device includes a stator, by which the rotor is magnetically driven without contact for rotation about the desired axis of rotation in the operating state.
