    摘要: A brushless direct current motor is energized by a power stage. Switches of the power stage are selectively switched by an electronic control device. In order to determine the correct commutation pattern, without using rotor position indicators, the control device is arranged to tap the power fed to the motor. The samples received by the motor, in an ordered sequence, define an analogue function whose parameters can be determined by vector addition. The computations applied to the sample enable the necessary commutating information and signals to be generated in a particularly rapid manner.

    摘要: An optical position measuring instrument including a scale and a scanning unit, wherein the scanning unit and the scale are movable with respect to one another. The scanning unit includes a detector unit, and a reflector unit that has a first and second wave front correctors and a beam direction inverter. The reflector unit is disposed so that beams first pass through the scale and the first wave front corrector, then a back-reflection of partial beams is effected in a direction of the scale, and the partial beams then pass through the scale and the second wave front corrector before the partial beams then arrive at the detector unit, wherein it is ensured that wave front deformations of the partial beams are converted into wave front deformations that compensate for resultant wave front deformations of the partial beams upon a second diffraction at the scale.

    摘要: An optical position-measuring device includes a measuring standard and a scanning unit. The measuring standard includes an incremental graduation and at least one reference marking at a reference position. The reference marking has two reference-marking subfields disposed in mirror symmetry relative to a reference-marking axis of symmetry, each of the subfields including a grating structure having a locally changeable graduation period. The scanning unit includes a divergently emitting light source, one or more gratings, and a reference-signal detector system. The reference-signal detector system has at least four detector arrays formed and positioned such that, from the scanning of the reference marking via the reference-signal detector system, first and second pairs of partial reference signals result, in each case having a signal pattern in phase opposition. The first pair of partial reference signals is offset by an offset amount relative to the second pair of partial reference signals.

    摘要: An optical position-measuring device includes a scanning bar extending in a first or second direction, and a scale extending in the other direction. The scale is offset by a scanning distance from the scanning bar in a third direction perpendicular to the first and second directions. The device has a light source whose light penetrates the scanning bar at an intersection point of the scanning bar and scale to fall on the scale and arrive back at the scanning bar. At a detector, the light is split by diffraction into different partial beams at optically effective structures of the scanning bar and scale and combined again. A periodic signal is obtained in the detector in response to: a shift between the scanning bar and scale in the first direction due to interference of combined partial beams, and a change in the scanning distance between the scanning bar and scale.

The scanning unit further includes a plurality of detector elements arranged downstream of the scanning grating, wherein the detector elements are arranged in the spatial directions in the detector plane, and wherein the detector plane is located in an area in which the bundles of beams coming from the scanning grating are completely spatially separated. The fringe pattern having a periodicity TPS is formed in the scanning plane by an interaction of the bundles of beams emitted by the light source with the measurement grating and the further optional gratings.
