    摘要: A method of determining the rotational speed of a three-phase brushless DC-motor, which comprises scanning at least one signal trace disposed on a revolving rotor of a three-phase brushless DC-motor by means of three sensors, each emitting a signal having two possible signal states, the signal trace and the sensors being of such construction and arrangement that eight values are realized by a logical combination of the two possible signal states, respectively, of the three sensors; detecting the rotor position with six of the values; and determining the rotational speed with the other two values.

    摘要: An apparatus for depositing sheets onto a stack permits improved alignment of the sheets on the stack. At least one conveying element provides for cyclical forward movement of the sheets into a position above the stack. At least one reciprocating aligning element is provided for stacked sheets. A device for controlling movements of the aligning element includes a computer. At least one linear actuator moves the aligning element and may be controlled by the computer.

    摘要: Method and device for measuring a dielectric response of an electrical insulating system, wherein a first measurement result is determined by a frequency domain method and a second measurement result is determined by a time domain method, whereupon the first measurement result and the second measurement result are combined to form an overall measurement result as the dielectric response. Standard types of measurement methods, for example the FDS and PDC methods, may be used as measurement methods for the frequency domain and the time domain.
