摘要： A magnetic bearing for generating magnetic forces. A configuration of electromagnetic poles and of permanent magnetic poles which, to the greatest possible extent, is planar enables the generation of a magnetic flux in the air gaps toward the rotor, also in the de-energized state. If this flux is modulated using a control flux, magnetic forces can be exerted upon the rotor for the purpose of providing magnetic support. This configuration makes it possible to provide magnetic bearings of a simple mechanical design.

摘要： A fault tolerant active magnetic bearing has at least three magnetically isolated control axes. To this end, the active magnetic bearing has a segmented stator which employs non-magnetic sections for magnetically isolating adjacent electromagnetic force actuators, and hence adjacent control axes. As a result, operating force actuators are not affected by magnetic poles experiencing a fault. Hence, in a three-phase active magnetic bearing rotor suspension control system, for example, full control of rotor shaft position can be maintained with only two functioning control axes.

摘要： The present invention relates to a magnetic bearing controller, capable of reducing the number of power transistors to control current as well as associated costs. Thrust commands FX, FY in X and Y directions, which are output from force control circuits to be added to a rotor, are subjected to pole coordinate conversion in a pole coordinate converter, into “F” indicative of a force magnitude and “A” indicative of a force direction angle. Then, a three-phase current value converter converts F and A into current values Cu, Cv, Cw for three-phase currents, and a three-phase current control circuit controls currents Iu, Iv, Iw, to be supplied to the three-phase windings, respectively, so as to match the currents with the current values Cu, Cv, Cw for the three-phase currents supplied from the three-phase current value converter, and excites three pole teeth of a stator, thereby compensating for a displacement of an axis of the rotor.

摘要： In an active magnetic bearing system employing radial or thrust bearings, rotor shaft position is determined without requiring air gap position sensors, resulting in a high reliability system. The flux paths for each respective electromagnetic force actuator of the active magnetic bearing are isolated in order to minimize the magnetic coupling therebetween. In this way, the current (or magnetomotive force, mmf) in each respective actuator is functionally related to the flux therethrough, independent of the currents (or mmf's) in adjacent actuators. Application of a digital PWM pole voltage waveform during normal bearing operation results in a ripple current waveform at the PWM switching frequency. The resulting change in stator pole current and pole voltage are measured, and the average differential inductance is determined therefrom. Then, with knowledge of the differential inductance and the average pole current, the effective air gap length, air gap velocity, and magnetic flux are determined according to the inherent magnetization characteristic of the magnetic bearing.

摘要： The present invention provides an active magnetic bearing (AMB) with improved configuration. The active magnetic bearing includes a stator which possesses only three magnetic poles. The three magnetic poles are arranged radially with an equiangular degree along an internal circumference of the stator and not in the same semicircle. Each of the magnetic poles is equipped with an individual power amplifier for providing coil current. In the other way, two of the magnetic poles can be equipped with only one power amplifier, and the other magnetic pole is equipped with an individual power amplifier so as to reduce the number of the power amplifiers.

摘要： In a rotary assembly comprising a rotor mounted in rotation in a stator about a mean axis of rotation, a radial position sensor comprises three induction sensors distributed in the stator substantially at 120° from one another around the rotor and equidistant from the mans axis of ration. The induction sensors are cabled in star connection with a common connection point, and are powered by a balanced three-phase sinusoidal voltage source with a neutral point. The output voltage, present between the common connection point and the neutral point of the balanced three-phase sinusoidal voltage source, is processed by signal processing means which determine its amplitude and its phase relative to the voltage delivered by the balanced three-phase sinusoidal voltage source. Thus, from only three sensors, two signals are obtained constituting the amplitude image and the angular position of the radial displacement of the rotor gravity axis in the stator.

摘要： A fault tolerant active magnetic bearing system comprises a magnetic bearing having a rotor mounted for rotation within a stator and for coupling to a shaft. An electric power distribution system is energized from a multi-phase switched reluctance machine supplying three independent DC power buses. Each of the power buses is coupled for supplying power to a respective pair of diametrically opposite electromagnets of the magnetic bearing so as to establish multiple magnetic control axes. Multiple power controllers are each operatively connected in circuit with a separate respective power bus. The power controllers include independent power control systems each coupled to a respective pair of diametrically opposite electromagnets for independently controlling energization of each one of the pair of diametrically opposite electromagnets.

摘要： A radial magnetic bearing system for use in turbomachinery, machine tools and so forth is disclosed. A rotary yoke made of a magnetic material is rigidly secured to a rotary shaft, and an electromagnet stator is rigidly secured to a casing. The stator is arranged to generate magnetic attraction forces radially at equi-angular spacings of 120.degree. within a plane perpendicular to the axis of the rotary shaft. Three displacement sensors are arranged such that each sensor measures displacement of the rotary shaft with respect to the casing in the direction of one of the three magnetic attraction forces, thus controlling the level of each magnetic attraction force.
