摘要： A magnetic bearing for suspending a rotatable shaft comprises a backiron (1), and a plurality of poles (2) fixedly coupled to the backiron and extending radially inward toward the rotatable shaft (6). The magnetic bearing also comprises a plurality of electromagnetic coils (4) each being circumferentially disposed around the backiron or the poles, and a magnetic target ring (5) fixedly coupled to the rotor shaft. Each of the poles is separated from the magnetic target ring by an airgap (3). The magnetic bearing further comprises one or more electrical circuits electrically coupled to the plurality of electromagnetic coils and being adapted to energize the plurality of electromagnetic coils so that magnetic flux is induced in the airgaps. The magnetic bearing includes features providing relating to fault detection and fault-tolerant operation. The magnetic bearing also includes mechanical and control-system features that reduce the power consumption of the magnetic bearing.

摘要： A magnetic bearing system and related method that utilizes self-sensing in order to determine and adjust the position of a shaft within the bearing. Magnetic bearings levitate a rotating object with a magnetic field and are unstable in open-loop operation. Position feedback control is required to maintain a rotor in a centered position. The system and related method uses a unique design to sense the position of the rotating object with greater accuracy. It comprises coils which are used both to detect and adjust the position of the rotating object and a control system which supplies signals in a time-multiplexed manner in order to determine the position with accuracy while still allowing the same coils that are used to detect position to also supply a field to control the position of the rotor.

摘要： A pump for pumping sensitive fluids, such as blood, having no mechanical contact between the impeller and any other structure. The pump comprises a pump housing (4), an impeller (7) disposed within the pump housing, a magnetic bearing system (5, 6) for supporting and stabilizing the impeller (7) in five degrees of freedom, and a conformally shaped magnetically linked motor for rotating the impeller (7). The magnetic bearing system (5, 6) and motor advantageously comprise electromagnets and permanent magnets (18) for stability and control of the impeller (7) and to reduce size, weight and pump power consumption. Permanent magnets (18) and electromagnets are disposed on the pump housing (4) and permanent magnets (18) are disposed on the impeller (7) such that by controlling electric current through the electromagnets on the housing, the magnetically suspended impeller (7) functions as the rotor and the housing as the stator of a D.C. motor. The system advantageously allows for sensing of relative impeller position and dynamic properties without the need for additional sensors.

摘要： Method and System of lubricating at least one moving part with a medium. The medium includes a dissolved mixture of lubricant and compressed gas. The amount of lubricant and compressed gas may be controlled in forming the dissolved mixture in response to input conditions. A user and/or external factors may be used to determine the input conditions. In response to the input conditions the amount of lubricant and compressed gas is delivered to the moving part that is housed in a pressurized chamber. The properties of the dissolved mixture can be adjusted, whereby the properties may include, but are not limited to, the following: viscosity, temperature, and thermal conductivity. This adjustment to the gas may be accomplished, for example, by releasing gas from the pressurized chamber in an amount to adjust the properties. In a further approach, lubricant may be scavenged from the pressurized chamber by returning surplus lubricant to its original source or other designated location.
