    摘要: A position measuring system to determine the absolute angle position of a rotor of a motor during startup. With this absolute angle position, correct commutation for startup of the motor is provided. During later operation a high-precision incremental angle measurement is possible. For this purpose a switching unit is disposed between a rotary transducer and an evaluation unit, which is driven in such a manner that first the analog signals necessary for the determination of the absolute angle position are input to the evaluation unit and thereafter the analog signals required for incremental angle measurement are input to the evaluation unit. In order to avoid unacceptable incorrect positioning in case of incorrect switching between the first and second modes of operation, all the analog signals have an approximately equal spacing period.

    摘要: A method for position determination of a rotating drive element with the aid of a measuring system is indicated, which comprises an absolute and an incremental measuring subsystem. Here, following the start of a rotary movement, absolute position measurement values are continuously determined and transmitted to a subordinated evaluation unit until a reference marking at a known absolute position has been reached. A comparison of the measurement values, known from the continuing absolute position measurement, with the known absolute position and, if required, a necessary correction, take place at the reference marking. Thereafter the reference marking is used as the reference position for the incremental measuring subsystem, the continuously absolute position is determined on the part of the measuring system and is transmitted in digital form to the evaluation unit (FIG. 1).

    摘要: A field-modulating angular position measuring device includes a scanning device, a measuring graduation, and evaluation electronics, the scanning device and the measuring graduation being arranged at a scanning distance rotatably relative to each other, and angle-dependent output signals being producible by the scanning device, which may be processed further in the evaluation electronics. The angular position measuring device furthermore has a unit for determining the signal amplitudes of the output signals. The angular position measuring device furthermore includes a temperature sensor, which is able to determine a temperature in the angular position measuring device. The angular position measuring device is configured such that the scanning distance may be determined on the basis of the temperature and the signal amplitudes. Furthermore, a method for operating such an angular position measuring device makes it possible, e.g., to determine a change in length of a shaft.
