A pump (10) includes a housing (14) having a fluid inlet (2 6) and a fluid outlet (28). A rotor (12) is disposed within the housing (14) and rotatable about an axis (16) to move fluid from the fluid inlet (26) to the fluid outlet (28). A magnetic axial bearing (286) for supporting the rotor (12) includes an axial bearing target (70) disposed on the rotor and an axial bearing stator (13 0) disposed on the housing, the axial bearing stator including multiple stator poles (132a, 132b, 132c) each including a first coil portion wound in a first direction and a second coil portion wound in a second direction opposite the first direction.

Antriebsgehäuse (27) und Propeller (3) sind insbesondere Teil eines Pod-Antriebes. Die Lagerung ist beispielsweise eine Azimutlagerung (61). Die Azimutlagerung (61) kann ein axiales Lager und/oder ein radiales Lager aufweisen. Ein Magnetlager kann auch zur Lagerung einer Welle zum Antrieb des Propellers (3) verwendet werden.
Abstract:
The core inside a combined radial-axial magnetic bearing is stacked with coated laminations each equipped with at least one radial cut. These cuts prevent the inducement of circulating currents caused by varying axial control fluxes through the central hole of the stack. Magnetic symmetry is preserved by pivoting every lamination with respect to the previous one over a particular angle. This arrangement not only reduces the losses in the bearing, but improves the performance of the axial channel as well.

Abstract:
The magnetic flux density by magnetic poles of electromagnets (M1 to M12) arranged at the same place in the axial direction of a rotor (1) at predetermined intervals in the circumferential direction of the rotor (1) varies gradually in the circumferential direction of the rotor (1). Even though there is a difference between the maximum and minimum of the magnetic flux density, the variation of the magnetic flux density between the magnetic poles of adjacent electromagnets is small and smooth. The sensitivity is good and stable sensing result is obtained.
Abstract:
A pseudo-levitation permanent magnet repulsive bearing and drive system arrangement for a large diameter, hollow centre composite flywheel for multi megawatt hours energy storage. The magnets are positioned in a frustrated cone to assist in centralising the running axis. The levitation system functions utilising multiple concentric rings of prime numbers of repulsive permanent magnets. Diaphragms, which deflect vertically and radially in concert with the flywheel as it speeds up, transmit torque between the flywheel and its drive system via a central drive shaft which rotates within active magnetic bearings or other bearing types. The lower fixed magnet arrays are elongated such that the cylindrical rotating magnets do not overhang at either end of the fixed magnet as the flywheel expands due to centrifugal force.
Abstract:
A turbine- generator device for use in electricity generation using heat from industrial processes, renewable energy sources and other sources. The generator may be cooled by introducing into the gap between the rotor and stator liquid that is vaporized or atomized prior to introduction, which liquid is condensed from gases exhausted from the turbine. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50KW to 5MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.
