    摘要: A drive arrangement with a first motor and a second motor is described, the first and second motor being coupled via a first coupling unit. The first motor is provided to generate uniform low-frequency movements and the second motor performs a higher frequency alternating movement to be overlapped. The total movement is transmitted from the second motor to a machine component coupled via a second coupling unit. The first coupling unit is configured to transfer the uniform low-frequency movement of the first motor to the second motor, wherein a transmission of the higher frequency alternating movement of the second motor to the first motor is suppressed.

    摘要: The invention relates to a method for guiding the displacement of a displaceable machine element (18) in a machine, comprising the following steps: a) specification of a guide target variable (xtarg) that describes the desired displacement operation of the machine element (18); b) determination of a pilot actual variable (Mpilot) and/or a guide actual variable (xact) from the guide target variable (xtarg) using a model (2), said model (2) comprising a path model (3), which simulates the dynamic behaviour of the elements (16, 18) involved in the displacement. The invention also relates to a device that corresponds to the method. The invention permits the optimised guidance of the displacement of a displaceable machine element (18) in a machine.

    摘要: An induction apparatus includes a winding arrangement having a winding start and a winding end for inducing a magnetic field in a magnetizable core; and a lossy, magnetizable device through which and/or about which the winding start and the winding end of the winding arrangement is so disposed as to induce a magnetic flux in the magnetizable device. This arrangement prevents an electric breakdown at the star point of winding strands of synchronous motors.

    摘要: An aircraft includes a propeller and an electric motor which is constructed in the form of a drive for the propeller. The electric motor includes at least two air gaps that can be used for cooling. The air gaps define an axis of symmetry which corresponds to an axis of rotation of the propeller.

    摘要: A system for guiding movement of a movable machine element of a machine, such as a machine tool, production machine and robot, receives user input data relating to a travel movement of machine element and an optimization criterion selected from a robust travel movement, where a smallest number of natural frequencies of the movable machine element is excited, and a time-optimized travel movement, where from the natural frequencies of the movable machine element only those natural frequencies are excited that do not include a main natural frequency. The system then determines from the movement profile coefficients of polynomial functions and a position setpoint variable based on the coefficients. The travel movement of the machine element is executed in response to the determined position setpoint variable.

    摘要: A measuring and simulation system for a machine-tool or production machine is described. Measurement results and simulation results are visualized simultaneously side-by-side on a common monitor display screen. A user can then easily set and optimize the control parameters of the machine-tool or production machine by a straightforward comparison between the measurement results and the simulation results.
