    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.

    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 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.
