    摘要: 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.

    摘要: 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.

    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.
