    摘要: A low-wear sensor with little structural outlay to detect a combined linear and rotational movement, such as in a print roller (10). In one embodiment, a PLCD (Permanent Magnetic Linear contactless Displacement) sensor includes a magnet (5) which can be rotated about a longitudinally extended coil (2). A ring magnet is particularly suitable for this. The linear position of the ring magnet can be determined independently of its rotational movement (7) by means of the voltage induced in coils (3,4). Detection of the linear position is contactless and thus wear-free.

    摘要: A control arrangement for an electric drive with a control which processes desired values and actual values of the electric drive in relation to a desired-actual control is provided. A determination device determines a derived variable in an iterative manner in accordance with the actual values and the derived variable is fed to an evaluation device. The evaluation device associates the derived variables with position values of the drive and determines, after accumulating several derived variables, characteristic values of a systematic error in the desired values and/or the actual values. In accordance with the determined characteristic values, the evaluation device determines correction values and switches the correction values to the desired values, the actual values or the difference of desired and actual values.

    摘要: Two sensors scan a measuring scale, which can be displaced in relation to the sensors and comprises a plurality of equidistant measuring gradation, and deliver corresponding measuring signals. The measuring signals are periodic during a uniform relative displacement of the measuring scale, essentially sinusoidal and essentially phase-shifted by 90° in relation to one another. They have an essentially identical amplitude and a base frequency that corresponds to the relative displacement of the measuring scale. During a delivery period of measuring signals, the measuring scale carries out a relative displacement through one measuring gradation. Corrected signals are determined from the measuring signals using correction values. A signal of the position of the measuring scale in relation to the sensors is determined in turn using said correction signals. Fourier coefficients are determined in relation to the base frequency for the corrected signals or for at least one supplementary signal that is derived from the corrected signals, said coefficients being used in turn to update the correction values. Said correction values contain two shift correction values at least one amplitude correction value and at least one phase correction value for the measuring signals, or part of said values, in addition to at least one correction value for at least one higher frequency wave of the measuring signals.

    摘要: The invention relates to a magnetic bearing control device and the use of a three-phase converter for controlling a magnetic bearing. According to the invention, a three-phase converter (70) is used for controlling a magnetic bearing (10, 66, 68), all three phase currents (40, 42, 44) of the converter (70) being used for controlling the magnetic bearing (10, 66, 68). A first solenoid of a couple of solenoids (10) of the magnetic bearing (10, 66, 68) is connected to a first (U) and a third (W) phase current output of the converter (70) while a second solenoid of the couple of solenoids (10) is connected to the first (U) and a second (V) phase current output of the converter such that the couple of solenoids (10) can be differently controlled by means of said one converter (70). The converter (70) can also be connected to magnetic bearings that already have a bias winding, which is advantageous for retrofitting such existing magnetic bearings, for example.

    摘要: In a method for operating a three-phase inverter of a converter-fed magnetic bearing, two coils are connected to respective outputs of the three-phase inverter at one end and are connected to each other and to a third output of the three-phase inverter at the other end. A variable control current is injected into the third output. A constant bias current flows between the respective outputs and thus serially through the two coils. The control current is divided among the two respective outputs so as to flow parallel through the two coils. This arrangement significantly reduces the effective current load of the three-phase inverter and significantly increases the slew rate of the control current.
