摘要： The invention relates to sensorless position determination for magnetic mounting. Magnetic mounting is used to mount an object with the aid of a magnetic field which is generally produced by an electromagnet. The position of the object relative to the bearing is of interest for controlling the bearing. The object position can be determined by estimating the inductance. The inductance is estimated with the aid of a least-squares method, wherein the electrical resistance of the bearing should be taken into account. The resistance is subject to certain variations, for example on account of temperature fluctuations. However, an incorrect resistance value is reflected in the estimated inductance error (I). A method which can be used to adapt the resistance is therefore proposed. The electrical resistance can be estimated by controlling the inductance error ΔL̂ to zero. In this case, the resistance adaption consists of a low-pass filter and an I controller.

摘要： The invention relates to a sensor system for a magnetic bearing, comprising two actuator coils (1, 2), two clocked power output stages (4, 5), a current sensor (3) for detecting those currents in the actuator coils (1, 2) which are encumbered with a ripple current, and a sensor interface (6), wherein the clocked power output stages (3, 4) provide a pulse-width-modulated output voltage, the pulse width of which is narrowed or widened by small amounts in each case in a predefined order, and wherein the pulse widths of the clocked power output stages (3, 4) are modulated in a fixed phase relationship with respect to one another. The sensor system mentioned achieves the object of specifying a sensor system for a magnetic bearing with a clocked power output stage. The invention also relates to a magnetic bearing, to a control device for a magnetic bearing and to a method for detecting the position in a magnetic bearing.

摘要： An active magnetic bearing (100) with automatic detection of the position thereof, comprising antagonistic first and second electromagnets (120, 130) forming stators disposed on both sides of a ferromagnetic body (110) forming a rotor maintained in a contact-free manner between said electromagnets. The electromagnets (120, 130) each comprise a magnetic circuit (121; 131), essentially consisting of a first ferromagnetic material and defining a gap with the ferromagnetic body, in addition to an exciting field (122; 132) which is fed by a power amplifier whose input current is controlled according to the position of the ferromagnetic body in relation to the magnetic circuits of the electromagnets. The position of the ferromagnetic body (110) is measured from the inductance detected between the two electromagnets (120, 130) reacting to the simultaneous injection into the two antagonistic electromagnets of a sinusoidal current having a frequency which is higher than the bandwidth in a closed loop of the system. The magnetic circuit (121; 131) of each electro-magnet also comprises a portion (124; 134) in the vicinity of the exciting field coil (122; 132) using a second ferromagnetic material whose magnetic permeability is lower than that of the first material and whose electric resistivity is greater than that of the first material in order to promote the passing of high frequency magnetic fields generated in the bearing.

摘要： An electromagnetic rotating machine having drive windings and position control windings and components enabling operation generally in accordance with the following.
The controller 82 estimates displacement of the rotor 50 by computing from the currents 1u2, 1v2 and 1w2 of the position control windings C2, the primary current frequency command value 2ω, and the output current (or voltage) from the inverter 56. On the basis of the estimated rotor displacement, the modulator 84, two-phase/three-phase converter 86 and voltage control inverter 88 control the currents of the windings C2. This unbalances the magnetic field generated by the motor windings C4, so that radial magnetic force acts on the rotor 50 to control the rotor position.

摘要： In order to stabilise a body borne contactlessly in the magnetic field of a stator, there is a magnetic bearing regulator which influences the magnetic field between magnetisable components in the stator and magnetisable components of the body. The bearing unit consists of at least two electric coils connected in series which, as a pair of coils, act as both a position sensor and an electromagnetic adjuster. In order to attain great reliability with a simple and economical construction, the two outer ends of the pair of coils (2, 3) are each connected to an output of an amplifier (4, 5) and one of the two amplifiers (5) supplies the inverted output signal of the other (4). A high-frequency signal is applied to the inputs of both amplifiers (4, 5) by an oscillator (7) which feeds into the pair of coils (2, 3) via the amplifiers (4, 5) and received between the two coils via a high-pass filter (12) by a phase-sensitive rectifier (8) which is in synchronism with the high-frequency signal from the oscillator (7). The output of the rectifier (8) is connected to the amplifiers (4, 5) via a downstream regulating network (9).
