摘要： A magnetically-levitated blood pump with an optimization method that enables miniaturization and supercritical operation. The blood pump includes an optimized annular blood gap that increases blood flow and also provides a reduction in bearing stiffness among the permanent magnet bearings. Sensors are configured and placed optimally to provide space savings for the motor and magnet sections of the blood pump. Rotor mass is increased by providing permanent magnet placement deep within the rotor enabled by a draw rod configuration.

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： A magnetic levitation control apparatus comprises a pair of electromagnets for holding a levitated body having a magnetic body in the levitated state. A signal source for supplying a voltage signal of a frequency on a level such that enables the electromagnets to function as the position sensor, wherein a control voltage signal for controlling the magnetic attraction of the electromagnets is superimposed on the voltage signal. A circuit differentially supplies the voltage signal to the pair of electromagnets to form a position signal of the levitated body from an add signal of currents respectively from the electromagnets, and a circuit detects a control current of the electromagnets from a subtraction signal of currents respectively from the electromagnets. A controller generates a control voltage signal of the electromagnets from the detected position signal of the levitated body and, in addition, corrects the position signal detected from the detected control current of the electromagnets.

摘要： The invention concerns a rotary pump (PP) for sucking in a liquid such as hydrocarbon comprising a pump wheel (1) integral with a rotor (4) immersed in part of the liquid sucked in by the pump. A motor (11) comprising a stator element (111) mounted in a frame (5) and a rotor element (110) mounted on the rotor (4), drives in rotation the rotor (4) about an axis (40). Radial (7, 8) and axial (9, 10) magnetic bearings support and guide the rotor (4) inside a chamber (6). A liner (61) is provided for protecting the motor (11) stator element (111) against the liquid. The pump is characterised in that the rotor (4) comprises at least one groove (45, 46) on an outer surface covered by the liquid, in particular for reducing the inertia effects caused by the liquid.
