    摘要: The invention relates to a device for measuring the steering rack path of a motor vehicle steering system, which has a steering actuation device and a steering rack actively connected thereto. Said steering rack can be displaced in an essentially linear manner and pivots the wheels into a desired position via additional elements such as a steering tie rod and a steering knuckle arm. One or more field-producing means are provided in the vicinity of the steering rack, the material thereof consists of a plastic-bonded permanent-magnetic material, and has/have a course of the magnetic field line and/or course of the magnetic field intensity according to the Nonius principle. In addition, at least one sensor module is mounted in a fixed manner next to the steering rack, has at least one magnetic field sensor and at least one sensor switching circuit, and transforms the course of the magnetic field line or course of the magnetic field intensity into output signals, which can be processed further and which indicate a linear path change or the position of the steering rack in the direction of its longitudinal axis.

    摘要: The invention relates to a method for operating an electronically commutated synchronous machine, which comprises a stator having at least two, in particular three, phase windings and a rotor having at least one permanent magnet, wherein a control factor is determined periodically for each individual phase winding, and the time periods during which an upper and a lower supply voltage is applied to said phase winding via switches of an actuation circuit which are assigned to the phase winding are determined on the basis of said control factor. In accordance with the invention, the electronically commutated synchronous machine is actuated according to a method for space vector modulation, in which zero vectors are applied to the phase windings at the beginning and/or at the end of a period for a switch-off duration, wherein in each case either all of the switches connected to the upper supply voltage or all of the switches connected to the lower supply voltage are on, and wherein the selection of the zero vector, i.e. whether the conductive connection to the upper or the lower supply voltage is produced, is performed in accordance with the phase winding with the greatest, in magnitude, deviation from the average control factor, which expediently corresponds to the average of the upper supply voltage and the lower supply voltage. In addition, the invention relates to an actuation circuit and the use thereof.

    摘要: The invention relates to a method for the sensorless, electrical measurement of the position of a rotor of a permanently excited synchronous machine which is fed by a converter, by means of measuring signals which are supplied to an evaluation system which determines the electrical position of the rotor according to the angle of the spatial current indicator for an applied stator flux pattern. The evolution of values of the differential spatial current indicator varies in an approximately sinusoidal manner with the double of the value of the electrical rotor position angle sought. The inventive method, which can be used especially for stationary or blocked machines, is characterised in that the evolution of values is formed from two respective successive measurements for an approximately inverse magnetisation, in such a way that the superposition of the applied stator flux and permanently excited rotor flux enables, due to saturation, an evolution of values of the differential spatial current indicator having two different maximum values, from which the electrical rotor position angle sought is directly and clearly differentiated to 360°.
