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.

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： A piezo actuator includes an adaptation element, which is configured to adapt the piezo actuator to a controller for inductive loads, particularly to a converter for actuating inductive loads. The adaptation element allows use of controllers or converters of numerical control systems, which normally are used for actuating servo motors. Therefore it is no longer necessary to provide specially designed hardware for the actuation of piezo actuators, but instead the above-mentioned controllers can be used. Furthermore, as a result of the adaptation element, the piezo actuators can be integrated in the bus of the numerical control system. This allows communication in real time via the NC bus.

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： A device for compensating a torque produced on a movable axle in a machine tool or production machine by a gyrostatic effect includes a rotating useful machine system attached to the movable axle and producing a useful angular momentum, and a rotating machine counter-system attached to the axle and producing a counter angular momentum. The magnitude of the counter angular momentum is substantially identical to the magnitude of the useful angular momentum. The useful torque produced by a movement of the rotating useful machine system through a temporal change of the useful angular momentum is at least partially compensated by a counter-torque produced by a temporal change of the counter angular momentum. This arrangement represents a simple device for compensating a torque produced by the gyrostatic effect on a movable axle of machine tolls and production machines.

摘要： In a method for increasing the control dynamics of a load driven by a direct drive via a driveshaft, a first transducer provides a first output signal indicating a first rotation speed, and a second transducer provides a second output signal indicating a second rotation speed. The direct drive is located between the first transducer and second transducer, with the second transducer being located in close proximity of the load. A mixed rotation speed is computed from a linear combination of the two rotation speed values, which is used as an actual control value of a controller of the direct drive. This method provides a very simple approach for increasing the control dynamics of a load driven by direct drive via a driveshaft.
