    摘要: The invention relates to a magnetic bearing control device and the use of a three-phase converter for controlling a magnetic bearing. According to the invention, a three-phase converter (70) is used for controlling a magnetic bearing (10, 66, 68), all three phase currents (40, 42, 44) of the converter (70) being used for controlling the magnetic bearing (10, 66, 68). A first solenoid of a couple of solenoids (10) of the magnetic bearing (10, 66, 68) is connected to a first (U) and a third (W) phase current output of the converter (70) while a second solenoid of the couple of solenoids (10) is connected to the first (U) and a second (V) phase current output of the converter such that the couple of solenoids (10) can be differently controlled by means of said one converter (70). The converter (70) can also be connected to magnetic bearings that already have a bias winding, which is advantageous for retrofitting such existing magnetic bearings, for example.

    摘要: In a magnetic bearing arrangement, support coils are connected in series and can be fed with a current. By coupling a point connecting the two support coils to a voltage source, the support coils can be used as actuating elements and, by feeding the support coils with voltage pulses, the inductance of the support coils can be inferred which is an indication of the position of the body to be mounted. This provides for a position control arrangement. Using one and the same support coils, both a stably controlled load-bearing capacity can thus be produced and at the same time a position sensor can be replaced.

    摘要: In a method for operating a three-phase inverter of a converter-fed magnetic bearing, two coils are connected to respective outputs of the three-phase inverter at one end and are connected to each other and to a third output of the three-phase inverter at the other end. A variable control current is injected into the third output. A constant bias current flows between the respective outputs and thus serially through the two coils. The control current is divided among the two respective outputs so as to flow parallel through the two coils. This arrangement significantly reduces the effective current load of the three-phase inverter and significantly increases the slew rate of the control current.

    摘要: In a spindle rotor, the orientation of the figure axis is accepted and the anchoring of the rotor bearing (SL) is configured such that the orientation of the geometric rotational axis adapts to the physical main axis of inertia. The bearing is configured in the form of an actively controlled bearing, whereby the orientation is measured and is dynamically carried out, but also in the form of bearing comprising passive elements which are associated with the external ring of the bearing and enable a correspondingly dynamic orientation of the bearing. A damper (T) is provided to dampen the vibrations of the bearing (SL).

    摘要: A circulating mechanism includes a moving member, e.g. a chain or a belt, which travels along a circulating path and is looped about at least one deflecting member for reversing a travel direction of the moving member. Disposed in a section of the circulating path is a guide assembly for guiding the moving member. A magnetic field generating device is provided for applying a magnetic force upon the moving member at least in an area of the guide assembly so as to draw the moving member against the guide assembly and thereby enhance the travel behavior of the moving member.
