| 20080215164 | Method and Device for Controlling Movement of a Movable Machine Element of a Machine - The movement of a machine element associated with a machine axis of a machine is simulated with a model by inputting in the model a movement to be performed by the machine element, and determining with the model at least one of a position profile, a velocity profile and a torque profile suitable for optimized movement of the movable machine element, as well as a predetermined quality function and a limitation for the movement of the machine axis. The position profile, velocity profile or torque profile is then used as a reference or pilot control variable in a control loop to control the moving machine element. The predetermined quality function is an integral of the square of a torque or of a variable which is directly related to the torque. The method can be used to optimize the guided movement of the machine element. | 09-04-2008 |

| 20090152478 | Arrangement comprising two elements which can be rotatably displaced in respect of one another - Data is to be exchanged between a rotating element and a further element, with the rotating element being rotated by way of a hollow shaft. Light is coupled into torus halves and is reflected into a torus half and onto torus inner walls so often by way of a small opening until it exits at an opening of the other torus half. In a first embodiment, a torus-shaped optical fiber is divided into two torus halves. In another embodiment, hollow tori are used, which are filled with a fluid, namely either with a liquid or with air. | 06-18-2009 |
| 20090160389 | METHOD AND DEVICE FOR GUIDING THE MOVEMENT OF A MOVEABLE MACHINE ELEMENT OF A MACHINE - The invention relates to a method for guiding the displacement of a displaceable machine element ( | 06-25-2009 |
| 20090174270 | DEVICE FOR SAFEGUARDING AN UNINTERRUPTIBLE POWER SUPPLY OF A MAGNET BEARING IN THE EVENT OF FAILURE OF AN ELECTRICAL SUPPLY VOLTAGE - The invention relates to a device for safeguarding uninterrupted power supply of a magnetic bearing ( | 07-09-2009 |
| 20090302699 | METHOD FOR MOUNTING A BODY - 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. | 12-10-2009 |
| 20090315505 | SYNCHRONOUS MOTOR, MOTOR SYSTEM AND METHOD FOR OPERATING A MOTOR SYSTEM - The invention relates to a synchronous motor ( | 12-24-2009 |
| 20100181855 | MAGNETIC BEARING CONTROL DEVICE HAVING A THREE-PHASE CONVERTER, AND USE OF A THREE-PHASE CONVERTER FOR CONTROLLING A MAGNETIC BEARING - 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 ( | 07-22-2010 |
| 20100317201 | Machine Tool or Production Machine or Robot - A machine tool or a production machine, such as e.g. a multispindle machine, or a robot, is described, wherein a liquid metal lubricated slide bearing is not only used to transmit feed currents for electrical consumers but also to transmit currents for producing control signals. Accordingly, it is possible to apply via the liquid metal lubricated slide bearings a voltage of 600 volts in order to produce feed currents and a voltage of 24 volts in order to produce control signals. | 12-16-2010 |
