摘要： An electromagnetic rotary drive includes a rotor including a magnetically effective core surrounded by a stator. The stator has poles arranged around the magnetically effective core and each of the poles is delimited by an end face. The rotor is capable of being magnetically driven without contact in an operating state about an axial direction, and is capable of being magnetically levitated without contact with respect to the stator. The rotor is configured to be magnetically levitated in a radial plane and is passively magnetically stabilized in the axial direction against tilting. The magnetically effective core has a rotor height which is a maximum extension of the magnetically effective core in the axial direction, the rotor height being greater than a stator pole height defined by a maximum extension of the end faces in the axial direction.

摘要： An electromagnetic rotary drive includes a rotor, a stator and windings. The rotor includes a magnetically effective core. The rotor is contactlessly magnetically drivable about an axis of rotation and the rotor is contactlessly magnetically levitatable. The stator has coil cores, each with a longitudinal limb parallel with the axis and a transverse limb extending radially, the transverse limb being perpendicular to the axis. The windings generate an electromagnetic rotational field, each winding surrounding one longitudinal limb, such that the stator is free of permanent magnets. The rotor is ferromagnetic or ferrimagnetic with one preferential magnetic direction extending radially, and the core of the rotor has a magnetic resistance in the preferential magnetic direction, the magnetic resistance at most half as large as the magnetic resistance in a direction, which is perpendicular to the preferential magnetic direction and perpendicular to the axial direction.

摘要： 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.

摘要： A flow regulator includes a first sensor determining a first actual value of a first flow parameter of the fluid, a pre-pressure regulator setting a predefinable pre-pressure at a pre-pressure outlet of the pre-pressure regulator, and a regulating pump. The fluid is capable of being supplied to the pre-pressure regulator at a plant pressure in an operating state via an inflow line and a pre-pressure inlet and capable of being conducted further to the regulating pump at the pre-pressure via a flow connection disposed between the pre-pressure outlet and the regulating pump, the pre-pressure outlet being connected to a high pressure connection of the regulating pump in a flow communicating manner via the flow connection such that the fluid is capable of being supplied from the pre-pressure regulator of the regulating pump and guided away from the regulating pump via a low pressure connection into an outflow line.
